Summer 2026 · 20 Jul – 9 Aug · Ko-START · Data infrastructure for international residents in Korea Seoul summers are hot and humid. The coast is far, and water parks run ₩40,000–50,000 with booking pages mostly in Korean. But a free beach opens right in the middle of Gwanghwamun Square. It's called Seoul Summer Beach, run by the Seoul city government and the Seoul Tourism Organization. Entry is free and it's a 2-minute walk from the subway. One catch: "it's free, just show up" can get you turned away — here's what to know first.

What's there — 3 zones

Water Wave Zone — for swimming. A large pool, an 8m-high water slide, and water buckets.
Play Wave Zone — for sand play. The centerpiece is "Sand Azit," a 12m-diameter dome sandbox. About 20 tons of sand from five beaches across Korea (Yangyang, Ganghwa, Daecheon, Busan, Gunsan) create a small beach in the city.
Play Market Zone — food & market. Food trucks and a small-business flea market. 🔴 Why you can't just show up — each zone has a different entry rule This is the key point. The sand playground (Sand Azit) uses advance reservations with a capacity per session. The official notice also mentions on-site intake, but its rules say extra entry depends on remaining places or no-shows.
