Great for a weary traveler
Visited the coal mine campground after driving a 500 mile day, so it was a set-up eat and crash situation. I did make a reservation on line, but that cost more than the $5 per site fee and was not necessary even though it was memorial day weekend. The fee is great because it is primitive, no electricity, no water at all, not just hookups, but the bathrooms were nice and clean with no sinks.
If you are prepared for a primitive camp with your own water and batteries for your electronics it is great. They have fire rings, grills, picnic tables and level places for tents.There are also nice back-in sites for boondocking RVs and the road up to the campground is fine for big rigs.
I ran into two mountain biker's here from Ireland that were riding the Continental Divide trail from The Mexican border in New Mexico to the Canadian border in Montana. They were staying here since the Trail goes through here. Paddy & Conner were very interesting people and I was fortunate to have run into them here.
I enjoyed my stay with a peaceful quite nights sleep and a short hike in the morning before breakfast cooked on the campfire. I would recommend this over a hotel stay if your passing through Grant's New Mexico on I40. You can probably get a site for the night anytime your passing through.
