First, locate your campground
Gain Campground lies at 108 Yaksu-ri, Bukha-myeon, Jangseong, near the Baegyangsa area of Naejangsan. Seorakdong Campground is at 25 Cheongbong-ro, Sokcho, near Seoraksan. These sites are far apart: they are alternative stays, not a same-day walking route.
Check-in depends on your accommodation
At both sites, the official guide gives 14:00 check-in and next-day 12:00 checkout for drive-in pitches, versus 15:00 check-in and next-day 11:00 checkout for four-person caravans. These are overnight accommodation rules, not opening hours for the surrounding national park.
What changes on November 15?
The posted standard rates at both sites are KRW 20,000 on weekdays or KRW 30,000 on weekends/peak dates for drive-in camping, and KRW 75,000 or KRW 100,000 respectively for a four-person caravan. The guide defines peak periods as July 1–August 31 and October 1–November 15 each year. The actual payable amount and vacancy require an individual reservation check.
Your vehicle can decide your pitch
Some low-emission pitches at Gain are restricted to electric/hydrogen vehicles or guests arriving by public transport, bicycle or on foot. Seorakdong separates ordinary A/B drive-in pitches from C camper-vehicle-only pitches: a standard car and tent cannot use C. Its caravans do not include bedding, towels or toiletries. Check separate notices for temporary vehicle-policy exceptions.
Before departure
Do not equate a published site guide with a confirmed booking or guaranteed winter operation. Recheck your dates, pitch type, seasonal closure notices and any updated policies on the official reservation system.
