There is only one, and it’s half way up the mountain road between the town and start of the bike park. Technically you could ride the road down to the bifpg gondola that takes you to the start of the BP, and then from the top follow the road down again to the campsite. It’s the one you can see on all the tourist maps – nightlife might be a problem depending on what you are after. A distinct lack of campsites in Andorra generally, bike park is awesome though
