How to Access The Trail 

Note to equestrians: Currently the trail south of Colossal Cave Mountain Park to Interstate 10 is not accessible to horses. Gates need to be installed, a horse route under I-10 adopted, gated and signed, and a safety issue north of Three Bridges needs to be resolved. Check here for updates. 

Sahuarita Road

The trail can easily be accessed at four points. From the south, the trail crosses the Sonoita Highway (Hwy 83) at Sahuarita Road. The northbound trail is directly east of the highway at Sahuarita Road and southbound trail is approximately 100 feet west of the cattle guard on Sahuarita Road. 

Three Bridges

The next access point is at Three Bridges. Northbound trail is on the north side of the road bridge, just west of the trestle and within a few feet of the north edge of the Cienega Creek embankment. 

The southbound trail follows an old right of way road that ends near the south end of the road bridge. Follow the right of way south until you come to the trail on your left before you get to the top of the hill (almost directly across from the Cienega Creek Trail parking lot). 

Colossal Cave Mountain Park

A link trail near the Cowboy Parking Lot is the southernmost access point inside the park. The parking lot is at the beginning of the one-way loop road at La Posta Quemada Ranch (near the group picnic area). The trail begins at an aluminum gate just west of the parking lot. 

The trail also can be accessed at the La Selvilla picnic area at the north end of the park. It can be found west of the restrooms and parking area  

Pistol Hill Road

The trail crosses Pistol Hill Road approximately 1.5 miles northeast of Old Spanish Trail. From Old Spanish Trail drive downhill on Pistol Hill, a well-maintained dirt road, to a cattle guard. There is room for parking above and below the cattle guard. The northbound trail begins at a gate in the fence north of the cattle guard. It goes to Rincon Creek, approximately 3.5 miles. 

The southbound trail is approximately 200 feet west (uphill) of the cattle guard, heading southwest about 50 feet in from Pistol Hill Road. Both of these trails have carsonite signposts, but the southbound signpost is not visible from the road.
