Planning Jeju snorkeling with kids? Choose designated beaches like Gimnyeong or Hyeopjae, where lifeguards are on duty. Haengwon Beach, known as Konan Beach, is famous for its water color and snorkeling, but the official tourism page doesn’t list operating hours, lifeguards or controlled zones like designated beaches do. With kids, the day’s waves and safety staff matter more than pretty photos.
2026 Jeju Beach Season at a Glance
As of 2026, Jeju’s 12 designated beaches were open from June 24 to September 6, with swimming hours from 10 a.m. to 7 p.m.
From July 15 to August 15, Samyang and Woljeong stayed open until 8 p.m., and Iho Tewoo and Hyeopjae until 9 p.m. Parasols were 20,000 won and platforms 30,000 won. Jeju announces the season and hours each year, so check before you go.
How the Three Beaches Differ
Gimnyeong Beach fits an east Jeju itinerary and is a solid first Jeju snorkeling spot for families. White sand and the Gimnyeong geotrail add a nature lesson to water play. The tourist information number is 064-728-3988.
For beginners, Hyeopjae Beach is the easiest Jeju snorkeling choice, known for shallow water and a gentle slope, making it family-friendly. It has public parking, restrooms and facilities, plus sunsets with Biyangdo Island. Pets are restricted in swimming zones in peak season.
Konan Beach is officially Haengwon Beach, at 575 Haengwon-ri, Gujwa-eup, Jeju City. Visit Jeju lists it as a Jeju snorkeling spot, but it doesn’t offer the same safety information as designated beaches, so don’t assume there are lifeguards or safety lines.
Which Beach Suits Whom?
Younger kids or kids nervous in water do best at a designated beach with shallow sections like Hyeopjae. If you’re staying in the east or want to add geology and village walks, Gimnyeong is a good fit.
Even experienced families should only take a short look at Haengwon on calm, clear days. Kids should wear life jackets and stay within arm’s reach. In June 2026, Korea’s Ministry of the Interior and Safety again urged using designated zones and wearing life jackets.
Suggested Day Routes
East route: arrive at Gimnyeong at 9:30 a.m., swim in the designated zone from 10, rinse and have lunch at noon, walk part of the Gimnyeong geotrail in the afternoon, stop at a Woljeong-ri cafe, and view Haengwon Beach only when the waves are calm.
West route: Hyeopjae Beach in the morning, lunch in Hallim, an indoor attraction or hotel rest in the afternoon, back to Hyeopjae after 6 p.m. for the sunset toward Biyangdo.
Doing Gimnyeong and Hyeopjae in one day means crossing Jeju City, so you’ll drive more than you swim. Pick east or west based on where you stay and keep Jeju snorkeling to one beach a day.
Parking and Public Transport
Hyeopjae has a public parking lot on the official map. Gimnyeong also has parking nearby, but it fills up from the morning in peak season, so arrive before opening.
Don’t approach Haengwon expecting a big tourist parking lot. Don’t block roads or residents; if parking is hard, move on.
Buses work, but transferring with wet gear and kids’ bags is tough. A round trip to one designated beach near your stay is more realistic.
Hours, Booking and Costs
Entry to designated beaches is free. As of 2026, parasols were 20,000 won and platforms 30,000 won; check gear rental and shower fees on site.
No entry booking is needed, but arrange a rental car, beach-side lodging and snorkel gear rental 2–4 weeks ahead. If you use a rental shop, check insurance, kids’ life jacket sizes and refund terms for bad weather.
Food and Cafes
Gimnyeong, Woljeong and Haengwon are close, so it’s easy to link east-coast cafes. Hyeopjae has many restaurants and cafes in Hallim. Kids tire fast after swimming, so choose one place with easy parking and restrooms rather than several famous spots.
Pros and Cons
The upside of Gimnyeong and Hyeopjae is a safety system during set periods and hours, plus easier access to showers and restrooms.
The downside is long waits for parking and showers in peak season. Haengwon is photogenic, but it lacks the official safety information and facilities families need for Jeju snorkeling.
