We love camping here. It's a beautiful park and you won't get bored. There are walking paths, bike trails, hiking trails. The lodge is great, with gifts, a restaurant, and a beautiful overlook. They have an overflow lot in case you're unable to get a reserved spot.
We stayed here to try out our new camper without going too far from home. It's not the most beautiful campground, but it's nice enough. Some of the sites have full hook up and others don't. There is not way I'm aware of to make online reservations, but you can call or stop in. There is a disc golf course and mountain bike trails in the Burns Park as well as a golf course and several other activities. The staff was nice and the facilities were clean.
Gulpha Gorge is a great campground. There are lots of good hiking trails in the Hot Springs National Park. While they do have nice restroom facilities, they do not have showers. The campsites are first come (not reservable). The sites could be a little better spaced apart, but it is still a nice campground. There are mountain biking trails and a disc golf course just up the road at Cedar Glades Park, which is nice.
Lake Ouachita is a great place to camp. Many of the campsites have views of the lake and are spacious. They all have a fire ring, grill and picnic table. They also have family bathrooms that have a private shower/sink area. They have a few hiking trails as well.
