Stayed in site 12 which was wedged between handicapped spot next to toilets and next RV over. Very small area although other campsites did not all appear so small. 

Nice dog-friendly hike on wajiji trail which begins from campground, crosses road and is out and back of~3.2 mi in total. Otherwise, dogs not allowed on trails in park.

As noted here, the road can be rough, and we accessed Chaco off Hwy 550 (we were told that accessing Chaco from other direction can be even more dicey if roads are wet). Road was washboard and beware of steel protrusions on sides of road which can be sharp. We made it fine in camper van but went slow.
