There are a series of BLM campgrounds along the Rio Grande River just outside of Taos. Easy access road- fully paved through a beautiful canyon.
Pilar is the first campground you come to on Route 570. It's across the road from the river, but there's a trail that leads to the shore. Also a great hiking trail that starts out of this campground and goes 9 mile, I believe, connecting all the campgrounds along this road.
This area is popular for rafting on the river and there's several companies running trips in the area.
RV sites (electric and water) are $15--or half off with senior pass. Tent sites are $7. All sites have picnic table and fire ring. Some sites have shade shelters.
Bathrooms with running water--no shower. But there are paid showers just up the road at Rio Bravo
Campground has 9 RV campsites with electricity and water; 3 tent campsites; and 2 picnic sites. This campground is open year round.
