In Korea for work at the moment and have been fortunate to be able to check out Sokcho and Seoraksan National Park. Definitely worth a visit, reminded me of Yosemite with the rock formations and steep climbs up to various peaks. There's easily 2-3 days hiking in the park with multi day options. Accessibility is pretty straight forward, around a three hour bus ride from Seoul and there are local buses to the main park entrance. Will definitely head back for a longer stint in the future.
