I'm the host at Split Mountain. In the late spring and summer it's a group campsite that's $40 per night. Reservations are highly recommended. The campground is on the Green River and close to the Quarry. Water, restrooms, and picnic areas are on site. It's close to a couple of trails, including the river trail which is the only trail in the park that allows dogs. It is also close to the boat ramp, where rafters take out after trips on the Yampa or Green. Remember to be courteous to other campers! Tents don't block sound and it's not polite to walk through someone's campsite (even if you're walking to the restroom). Also, one of the wonderful things about this spot and this park is the night sky! Even when there's a new moon I don't need a flashlight if it's a clear night. The stars provide enough light to walk around. Bright head lamps or flashlights can ruin the night vision of those around you, especially if you look at them while wearing the head lamp. I suggest a red or green light - it's easy to make a cover for your lights. By using colored lights, you can see if you need it and you won't zap the night vision away from other guests. This park is off the beaten path, but worth the time!
