We initially went to the left but were intimidated by the narrow road and didn't want to get in a pickle. We ended up camping to the right in the field because the road got a little rough further in…although we walked in later and it wouldn't be too difficult to access the nicer sites further in.
We were near the road, but it was still pretty quiet. It nice having access to Los Alamos and the hikes around that area.
It is right off of the main road but was pretty quiet the two nights we stayed there. There are some sites among the pines soon after pulling into the campground (on the right) and then there are more both further in and to the left upon entering if you're vehicle is 4x4 and has some good clearance…it wasn't so brave.
From the site it was only a quick drive to both hot springs and stream side hikes.
