Donghae Sundaeguk

Sokcho Tourist & Fishery Market

Sokcho's town-centre market, laid out as separate alleys for fish, dried seafood and household goods. The market-wide hours are given as 08:00–24:00, but individual stalls set both their own hours and their own closing days — check the one you are aiming for.

Seoraksan National Park

The park does not publish opening hours, it publishes a table of when you may start walking and when each gate stops you. Read that table before anything else: the Sogongwon trails run on sunrise and sunset, and everything beyond Biseondae runs on a clock that starts at 03:00 in summer.

Seorak Cable Car (Gwongeumseong)

The one ticketed thing on the Sokcho side of Seoraksan, and the one whose hours you cannot look up in advance: the operator posts them a day at a time. The fare page is stable, the timetable is not, and the two are on the same website.

Sinheungsa

You walk through it whether or not you meant to — the Ulsanbawi, Biseondae and Geumganggul trails all start past its gate, and the great bronze seated Buddha the park's own trail notes call the Cheongdong Daebul stands on the approach before you reach the temple itself.
