Colossal Cave Mountain Park: Camping and Picnic Areas – Vail AZ


The Civilian Conservation Corps (CCC) carried out major work at Colossal Cave and the surrounding park north of Vail AZ (now a suburb of Tucson, but far to the east in the 1930s). They improved access to the cave itself, built a large visitors’/administration center, laid out a campground and picnic area, opened roads and trails and built a water supply system.  The Arizona State Park Service oversaw the work.

CCC workers constructed La Selvilla campground and El Bosquecito picnic area below the hillside, as well as a pump house to take water up the hill to the cave and visitors’ center.   La Selvilla campground has very minimal improvements and a poorly maintained road, but El Bosquecito picnic area is quite nice and features concrete tables, stone stoves and a stone water fountain (now a faucet).

The former well and stone pump house are at El Bosquecito picnic area.

(Note:  It appears that the original CCC camp SP-10 was sited at the current location of the El Bosquicito picnic area, but we cannot confirm that).
