Visiting Carlsbad Caverns. Need RV Park. Where to U stay?

If you can do without services there is a really neat free boondock spot on BLM land se corner of nm 720 and Black River crossing. Place a spotter at the top of the west bound hill while you back in off 720. Believe me, its worth it.
The pond there is good bass fishing, Edit-- you must back in,off 720 there is no room to turn around. Look at google maps nm 720 and black river crossing.
