The website listed for this campground is correct Ponderosa campground Antonito, CO.
This is a very relaxing place to stay and it seems like most of the people there have been there many times before. The drive in is easy on Route 17 and does not require a vehicle with high ground clearance. They do allow campfires, they have clean bathrooms and a shower house. I stayed in a backpacking tent after driving all day arriving on a Friday at about 4:00 PM. The campground is set-up for small campers and has some cabins for rent too. The bathrooms with showers are clean and comfortable. The sites have fire rings with grates and picnic tables. The owner manager is great, providing quality fishing advice, conversation and even a free cup of coffee in the morning. Hiking on the CDT is near the campground and fishing is right in the campground. The steam train is right up the pass and I happened to be there the night before opening day catching a photo when I drove over the pass to Chama New Mexico. The Cumbres and Toltec Train traveling between Antonito, Colorado and Chama, New Mexico. This is a very nice drive and Chama is a cool place to visit, it is a trail town on the CDT.
I will visit this campground again for sure.
This campsite is only accessible via boat. There are two fire pits. The land is flat compared to other sites at the Reservoir. Most of the ground is covered with sand. The mosquitoes were not too terrible even though we were right by the water. There are no bathroom facilities just nature. It is a nice quiet cove with amazing views. The stars and the moon light up the sky. I highly recommend staying there if you have boat access. It is secluded and private.
