My visit: September, 2006. I was a bit surprised that there aren’t more public campgrounds within this national park, but Gulpha Gorge Campground is the only one.
43 campsites located on Business 70 (Exit 2 from 70E). No showers here, but drinking water, dump station, and restrooms are in the area. Sites cannot be reserved in advance; self registration on first-come, first-served basis. There is a nice large picnic area here, also. Site Map from NPS for info and rates on sites with and without hookups.
Gulpha Gorge Trail – This is a really pretty trail at the end of the campground that will take you to various lookouts along the way and can get you to Dead Chief trail and the Grand Promenade when it ends up in the downtown historic district by Bathhouse Row.
This is the 3-1/2 mile road to the Hot Springs Mountain Tower. It’s a one-way road, but no vehicles over 30 feet long are allowed due to sharp switchbacks. The tower is 216′ tall, affording spectacular views of the surrounding Ouachita Mountains, Hot Springs, and the surrounding Diamond Lakes area. To get here, turn off Central Avenue in downtown onto Fountain Street and follow the signs to the Tower.
