Jackson offers some of the best rock climbing in southern Illinois. There are about 60 climbing areas along the sandstone bluffs and freestanding boulders, with multiple routes. Most of the routes here are sport routes, though there are a number of trad routes.
There are primative campsites on both sides of Glen Street Falls Road near the trailhead. You can drive right up and park next to your campsite. If those campsites are full, there are additional campsites further down the road.
Most campsites have fire rings. There are no picnic tables or campfire grills there. There are also no garbage cans. You must pack out all of your garbage. You also need to bring your own drinking water as there is no fresh water there.
There's a single outhouse at the trailhead that is well maintained and pretty clean.
