We drove around looking for a place to boondock near Sisters for what felt like forever, but all the remote sites we planned on were taken. When we arrived at the Black Pine dispersed area, it was surprisingly empty for how busy the rest of the area was. 

The sites were huge with enormous fire rings and would be ideal for groups. We just had one small van, but there was one other large party with multiple vehicles and a large camper van, and they fit comfortably in one site. 

The actual sites are not very forested or private, but it still felt secluded since only two of probably 10 sites were taken. Definitely recommend this area, especially for groups!
