30 March, 2004. Caballo Lake State Park offers great views and remote, lakeside primitive campsites as well as sites with electricity. We decided on a primitive lakeside site and it was quite enjoyable. In fact, we found that New Mexico State Parks are among the nicest we've encountered. They have showers, modern plumbing and are well maintained. Prices average $8 for primitive, $10 for developed and $14 for electric sites.
