This is a great retreat from the city but close enough that it's easily accessible from Taipei. The site is probably only big enough to fit 5 or so tents, so I'd imagine that it fills up quickly in the summer. The site is open year-round. If you show up during off-season, the owner probably won't be there when you arrive... but don't worry, he'll show up to collect the fee.The cost is actually $200 ($100 per person plus $100 per tent). The facilities are kept very nicely, including three toilets, a hot water shower, and two cold water showers.Do NOT follow directions from Google Maps. Driving directions will drop you off in the middle of the highway while bus/walking directions will take you to a soy bean plantation. But the good thing is that everyone in the area knows where this camp is, so ask anyone and you'll find it easily... although it took me several tries to find someone who speaks Mandarin because this seems to be a Taiwanese-speaking community.Directions by public transit: Take the 923 bus from either Xindian Station or Xindian DIstrict Office to 坪林國中 (takes about 30 minutes). Walk in the direction the bus is facing to the first intersection and turn right. Walk for about 15-20 minutes until you see a bicycle path marked with a very large "自行車專用道" sign. If you miss it, you'll end up on an on-ramp to a highway (but a guard will yell at you to tell you to turn around). Walk along the bike path for another 15-20 minutes, which will take you right to the campsite.
