Hamdeok Beach Guide: Swimming, Seoubong, Parking & Northeast Jeju Travel Tips

Hamdeok Beach is a sand beach on Jeju's northeast coast with the Seoubong hill rising right beside it, and it fits a one or two hour stop or a longer swim day in summer. You can visit the shore at any time of year, but swimming belongs to the official summer season, and night swimming is not part of it.

Three questions decide the visit: whether you want to swim or just see the coast, which month you are coming, and how you are getting there. This page keeps beach access apart from swimming, and it keeps swimming apart from night swimming, because they are three different things.

Quick answer

Is Hamdeok Beach worth a visit?

Yes, if you want a beach with a hill walk next to it and you are staying near Jeju City or driving the northeast coast. The sand, the water color and the Seoubong viewpoint sit within one short stretch.

Hamdeok Beach vs Hamdeok Seoubong Beach: are they the same place?

They are the same beach. Visit Jeju titles the listing Hamdeok Beach (Hamdeok Seoubong Beach), and VisitKorea lists the Korean names 함덕해수욕장 and 함덕 서우봉 해변 together.

The second name exists because Seoubong, a volcanic hill, rises directly beside the sand. Seoubong is a separate place with its own Visit Jeju listing, not a second beach.

The hill's name appears in English as Seoubong, Seowoobong and Seowubong. I use Seoubong, and I use Hamdeok Beach for the beach. Search for 함덕해수욕장 in your map app and check that the pin sits on the shore.

Where it is

Hamdeok sits in Hamdeok-ri, Jocheon-eup, part of Jeju City, on the northeast coast. It is a beach town with shops and lodging behind the sand, not an isolated shore.

Straight-line distances below are my estimates from map coordinates. They are not road distances or travel times.

Beach basics

Access

Visit Jeju lists Hamdeok Beach as open at all times and shows no entrance fee, and VisitKorea lists it as open 24 hours with swimming hours that vary by season. I am not describing an all-year swimming schedule, because the open shore and the supervised swimming area are different things.

Being able to walk on the sand is not the same as an official swimming operation. The sections below keep access, swimming and night swimming apart.

Swimming and the beach season

Jeju's beaches have an official season set by the provincial government each year. For 2026, Jeju Sori, Jeju Ilbo and Newsjeju reported that 12 beaches, Hamdeok among them, opened together on June 24 and ran to September 6, with standard hours of 10:00 to 19:00. Visit Jeju's Hamdeok page gives the same 2026 hours.

That is a dated 2026 note, not a rule for other years. The 2026 season has ended, and I have not seen 2027 dates, so check the Jeju provincial announcement before you plan around swimming.

Outside the announced season I found no official statement about lifeguards or swimming rules here. I am not claiming any supervision then, and I would not treat the water as supervised.

Night swimming

Night swimming is not part of the 2026 operation. Visit Jeju's Hamdeok page says that the official swimming hours in 2026 are 10:00 to 19:00 and that nighttime swimming is not permitted.

The 2026 reports on extended hours name other beaches only: Samyang and Woljeong to 20:00, and Iho Tewoo and Hyeopjae to 21:00, for a period in mid-summer. Hamdeok was not on that list.

The same Visit Jeju page notes that a walking trail with night sea views draws visitors all year. Walking the shore after dark is access, not a swimming operation, and I would not go into the water outside the posted hours.

Lifeguards and safety

Reports on the 2026 season described safety staff at the open beaches, but the staffing figures disagree, so I am not printing any. I am not claiming lifeguards at other times of year.

Follow the flags, lifeguard instructions and posted notices. If the sea looks rough, stay out of it. Do not rely on any page, including this one, to tell you the water is safe.

Water conditions

Visit Jeju describes the water as clear and emerald-colored, and families do swim here. I am not describing the water as shallow or calm, and I am not giving depth, currents, tides or wave height, because those change by day and a guide cannot report them.

Treat any claim that Hamdeok is safe for children with caution, including older articles that call it calm and shallow. Stay within arm's reach of children and follow the lifeguards.

Parking

Parking exists. VisitKorea lists it as available, the Visit Jeju Seoubong listing tells walkers to use the parking near Hamdeok Beach, and the provincial beach dataset (data as of April 2026) lists 210 parking spaces.

I could not confirm whether parking is free or paid, which lots are public or private, or how it changes in summer. The dataset's count does not say whether every space is open year-round, and I am not repeating the prices that blogs and aggregator pages quote.

Lots near the shore can fill in the swimming season, so allow time to find a space. Do not block village lanes, and check the signs for the fee.

Facilities

The provincial dataset lists four restroom buildings, two shower facilities and three drinking fountains at Hamdeok Beach. VisitKorea also lists a snack bar, a restroom and a convenience store.

I could not confirm which of these run only in the swimming season, whether any have fees, or whether they are open outside it. I am not describing changing rooms, lockers or an accessible toilet, because I found no source for them. If you plan to swim, bring a towel and a change of clothes, and keep valuables in a bag or the car.

What to do

The beach

The draw is the sand against the Seoubong hill and the color of the water. The provincial dataset lists a sand area of about 12,000 square meters, which is smaller than Gimnyeong's, and the beach feels busy because of its visitor numbers more than its size.

Jeju Sori reported 703,064 visitors in the 2025 season, which made it the most visited beach on the island. The dataset gives Gimnyeong 36,026 and Woljeongri 33,650 for the same season, so expect more people here, especially in July and August.

The Seoubong walk

Seoubong is a hill beside the beach, and the Visit Jeju listing describes it as open at all times with free entry. It is part of Jeju Olle Route 19, which links Hamdeok to Gimnyeong.

From the hill you look back over Hamdeok Beach and, in clear weather, toward Hallasan and the oreum to the east. Visit Jeju says canola flowers cover the slope in spring and the grass turns green in summer. I am not giving a bloom date, because it moves with the year.

Korea Tourism Organization — Photo Korea

I did not walk Seoubong for this guide, so I am not giving a distance, a time, an elevation or a step count. Visit Jeju's older text calls the north slope very steep, so treat it as a real walk and wear shoes with grip.

The loop trail has no separate lighting, and Visit Jeju advises returning before sunset. Visit Jeju also notes that some oreum have restricted access or no parking, so confirm with the Jeju Tourist Information Center if you are unsure.

Swimming with a dog

In 2025 Hamdeok became the first Jeju beach designated to allow dog swimming. During the 2026 season a designated area in front of the Seoubong entrance ran as Ham Dog Beach.

That is a dated 2026 note. Check whether the zone runs again, and follow the posted rules on leashes and waste. I did not verify dog rules for the rest of the beach, so ask before bringing a dog onto the main sand.

Snorkeling

I found no official source that describes snorkeling at Hamdeok, so I am not covering it, and I am not naming any snorkeling operator. Do not assume the beach suits snorkeling because other Jeju beaches do.

Kayaks, SUP, surfing and boats

I found no current official source for kayaks, stand-up paddleboards, surfing or boat tours here, so the status of each is unclear and I am not recommending an operator. Old blog posts may describe rentals that no longer run.

If you want a water activity, ask the operator directly about conditions on the day. Wind and waves decide whether it runs.

How long to stay and when to go

These are my planning estimates, not official figures.

Seasons

Wind, waves and weather

The northeast coast is exposed, so the wind can feel strong even on a clear day. I am not giving a wind speed, wave height or tide time at which to skip the beach, because I could not source reliable thresholds.

Check the forecast and any sea warnings on the day. Visibility also decides whether the Hallasan view from Seoubong is worth the climb.

Families and accessibility

Hamdeok is popular with families, and Visit Jeju promotes it for family summer travel. That is not a safety claim, so keep children within arm's reach in the water and follow lifeguard guidance.

The Visit Jeju accessibility field reads "Difficult." I am not claiming step-free access to the sand, the facilities or the hill, so if you need level access, ask the local beach office before you go.

Getting there

By car

A rental car is the simplest way to reach Hamdeok and to link it with other stops on the northeast coast. The Jeju car rental guide covers the basics for visitors.

I am not giving a drive time, because it depends on the day, the traffic and where you start.

From Jeju City

Jeju City is to the west, about 14 km from the city hall in a straight line. By road it is a drive along the northern coast, and I did not time it.

From Jeju Airport

The airport is about 17 km west in a straight line. VisitKorea lists the distance as 20 km, which is a listed figure and not a drive time.

By bus or taxi

Bus routes to this coast change often, and I did not verify any current route number or timetable. Visit Jeju's public transport page, an older page dated 2022, points to the province's free real-time bus app, which has an English option.

Plan a return option in case the bus does not suit your schedule. A taxi is possible, but I do not give fares, since they depend on distance and traffic.

Nearby stops

Hamdeok and Gimnyeong

Gimnyeong is about 8 to 9 km east in a straight line, a white sand beach with dark lava rock and far fewer visitors in the 2025 season. The Gimnyeong guide covers it, and a day can hold Hamdeok in the morning and Gimnyeong after.

Both are swimming beaches only in the official season, and their facilities are set beach by beach.

Hamdeok and Woljeongri

Woljeongri is about 12 km east, with a cafe road and a sea wall behind the beach. The Woljeongri guide covers it, and it pairs with Hamdeok as a longer coastal drive.

I am not saying Woljeongri is cleaner, safer or better for swimming than Hamdeok, because I could not source that. Use it if you want cafes more than a hill walk.

Hamdeok in a Northeast Jeju plan

Treat Hamdeok as the west end of this coast. Pair it with one of Gimnyeong or Woljeongri, and add Manjanggul only if you check its hours first, because the cave has a closed day.

I would not make Udo, Seongsan, Seopjikoji, Woljeongri, Gimnyeong and Hamdeok one day. Udo needs a ferry with a fixed return, and the others each take real time. The East Jeju itinerary shows a realistic day, and the beach roundup helps with the choice.

Hamdeok compared with Gimnyeong and Woljeongri

This comparison uses the provincial beach dataset (data as of April 2026) and the 2025 season totals. It is not a ranking.

The counts are what the dataset lists. They do not say which facilities are seasonal, free or open outside the swimming season.

Common mistakes

1. Treating Hamdeok and Hamdeok Seoubong as two beaches. They are one beach with two names.
2. Treating Seoubong as the beach. It is a hill beside it, with its own listing.
3. Assuming you can swim year-round. Swimming is an official summer-season activity.
4. Using last year's season dates. They change each year.
5. Treating beach access as swimming supervision. Being able to walk on the sand is not the same as a staffed swimming area.
6. Assuming night access means night swimming. In 2026 the official hours ended at 19:00 and night swimming was not permitted.
7. Assuming the water is shallow or calm. Conditions change with tide, wind and waves.
8. Using an old parking price. I did not confirm a fee, and old figures online may be wrong.
9. Assuming every listed facility runs all year. Seasonal operation is not confirmed.
10. Booking a water activity from an old blog. Operators and seasons change.
11. Climbing Seoubong near dark. The loop trail has no separate lighting.
12. Treating Hamdeok, Gimnyeong and Woljeongri as one beach. They are separate beaches with separate facilities.
13. Packing Udo, Seongsan, Seopjikoji, Woljeongri, Gimnyeong and Hamdeok into one day. It is rushed.

FAQ

Is Hamdeok Beach the same as Hamdeok Seoubong Beach?

Yes. Visit Jeju titles the listing Hamdeok Beach (Hamdeok Seoubong Beach), so one beach carries both names.

Is Seoubong the same as Hamdeok Beach?

No. Seoubong is the hill beside the beach, with its own Visit Jeju listing and a walking route.

Can you swim at Hamdeok Beach?

In the official summer season, yes. In 2026 that ran June 24 to September 6, and other years need a check. Outside the season I found no official statement about supervision.

When is the Hamdeok beach season?

I can only date it for 2026, when the province ran it from June 24 to September 6. Dates for other years are announced separately, so check the current announcement.

What are the swimming hours?

In 2026 the official hours were 10:00 to 19:00, according to Visit Jeju and the season reports. Hours for other years need a fresh check.

Is night swimming allowed at Hamdeok?

Not in 2026. Visit Jeju says nighttime swimming is not permitted, and the reports on extended hours did not list Hamdeok.

Can I walk on the beach at night?

Visit Jeju lists the beach as open at all times and mentions a trail with night sea views. That is access, not a swimming operation, and the water is not supervised after the posted hours.

Are there lifeguards at Hamdeok Beach?

Reports on the 2026 season described safety staff at the open beaches, but the figures disagree. I am not claiming lifeguards at other times.

Is the water at Hamdeok shallow or safe for kids?

I am not making that claim. Conditions change with tide, wind and waves, so stay close to children and follow lifeguard and flag guidance.

Is Hamdeok Beach free to enter?

I found no entrance fee on the Visit Jeju listing. Parking, rentals and any private services are separate, and I could not confirm their costs.

Is there parking at Hamdeok Beach?

Yes. The provincial dataset lists 210 spaces and VisitKorea lists parking as available. I could not confirm a fee, so check the signs on arrival.

Are there toilets and showers?

The provincial dataset lists four restroom buildings, two shower facilities and three drinking fountains. I could not confirm which run outside the swimming season.

Are there lockers, changing rooms or an accessible toilet?

I found no source for any of them, so I am not claiming them.

Can I bring a dog to Hamdeok Beach?

A designated Ham Dog Beach area in front of the Seoubong entrance ran in the 2026 season. Check whether it runs again, and follow the posted rules.

Can I snorkel, kayak or surf at Hamdeok?

I found no current official source for any of them, so I am not covering them or recommending an operator.

How long should I spend at Hamdeok?

About 1 to 2 hours for the beach, and longer with the Seoubong walk or a swim. These are my estimates.

Is the Seoubong walk hard?

Visit Jeju's older text calls the north slope very steep. I did not walk it, so I am not giving a distance, time or elevation, and I would wear shoes with grip.

When do the canola flowers bloom at Seoubong?

Visit Jeju says canola covers the slope in spring. I am not giving a date, because blooms move with the year.

How far is Hamdeok from Gimnyeong and Woljeongri?

About 8 to 9 km and about 12 km east in a straight line, which are my estimates from map coordinates. They are not drive times.

How do I get to Hamdeok from Jeju City or the airport?

By car along the northern coast, which I did not time. Bus routes change, so check Visit Jeju or a navigation app on the day.

Is Hamdeok Beach wheelchair accessible?

I am not claiming it is. The Visit Jeju accessibility field reads "Difficult," so ask the local beach office before you go.

Is Hamdeok better than Gimnyeong or Woljeongri?

It depends on what you want, and I am not ranking them. Hamdeok has the hill walk and the biggest crowds, while the other two are quieter by the 2025 counts.

Is Hamdeok worth it outside summer?

For a short coastal look and the Seoubong walk, yes. It is a cold and windy coast in winter, so do not plan a beach day.

The bottom line

Treat Hamdeok as a beach and hill stop that becomes a swimming beach only in the official season, and only in daylight. Check that year's dates, read the parking signs on arrival, and finish the Seoubong walk before dark.
