Handam Coastal Trail

Gwakji Gwamul Beach

The designated season is the whole planning problem: outside it the shore is open but unstaffed, and inside it Gwakji is one of the beaches that closes at 19:00 with no evening extension. It is also the far end of the Handam Coastal Trail, so it is rarely worth driving to on its own.

Hyeopjae Beach

A beach in Hallim-eup on Jeju's west side, on Jeju Olle Trail Course 14. At low tide a long stretch of pale sand with crushed shell in it is exposed, the slope is gentle and the water shallow, and it runs into Geumneung Beach next door, which is why the two are usually called the twin beaches. Biyangdo sits offshore. The publisher lists the site as open at all times, but the bathing season — when it is staffed and supervised — covers only part of the summer, and that distinction is what decides when to come.

Hallim Park

A private theme park immediately south of Hyeopjae Beach. The publisher describes nine themed sections across a hundred thousand pyeong; besides the palm avenue and the gardens, lava tubes including Hyeopjaegul and Ssangyonggul lie inside it. What is worth noticing on this record is that the operator states its times only as when ticketing opens and when it closes, and publishes no closing time for the park at all.

Saebyeol Oreum

Choose the east trail unless you want the climb: the west one is the steeper of the two. It is open all year with no forest-fire closure period, which is not true of every Jeju trail, and the Jeju Fire Festival held here no longer sets the hillside alight — see the article.
