Tips for Adventure Travel in South Korea
1. Go seasonal. Many activities are season-specific so plan surfing in summer, ice climbing in winter, hiking and paragliding in spring/fall.
2. Book in advance. Paragliding, caving and surfing tours fill up quickly, especially on weekends, so pre-book online where possible.
3. Use public transport + taxis. Many adventure spots are remote, so take a train or bus nearby, then grab a local cab.
4. Learn some Korean phrases. Especially in offbeat locations, English might be limited, so basic Korean goes a long way.
5. Pack layers and grip shoes. Korea’s climate swings fast and many hikes or climbs require solid footwear.
