We have camped a couple of times in Golden Gate Canyon. This is a Colorado State Park. Both times we camped in Aspen Meadows Campground…..a tent only campground. There are other campgrounds in the park that have hook-ups. The sites are pretty spacious and we have been able to do group camping “of sorts” in this campground. This is a campground where you need reservations. Both times we were planning a church camping trip–so we called in the Spring when reservations opened up to get spots together. Lot’s of fishing is nearby as well. We went to Dude’s Fishing Hole.
Here is the link to the park for more information and also the link to Colorado’s State Parks.
