The Prospector is most often used as a connector trail to Church Rocks, but does run from Grapevine all the way to the Red Cliffs Recreation Area
There are three access points for the Prospector: 1. the Grapevine 2. Cottonwood Trailhead 3. the Red Cliffs Recreation Area.
1. The Grapevine is accessed just off of I-15 exit 13, the Washington Parkway Exit. Once of the exit turn toward the red rocks. The road will turn and head toward St. George at this bend you will see a dirt road. This is Grapevine. To access the Prospector from here, simply follow the Grapevine to the signs.
2. The Cottonwood trailhead is the most common access point for the Prospector and is the traditional starting point for the Prospector to Church Rocks ride. To get to this trailhead, head North on I-15 and take the Hurricane Exit 16. This will put you on Highway 9. At the first traffic light, turn left onto Old Highway 91/6300 West. Follow this through the industrial area watching on the left for Winkel Distributing. Winkel distributes beer so watch for beer trucks. Pull into their parking lot and on your right you will see a dirt road that goes under I-15. Follow this dirt road to the other side of the freeway and you will be at the trail head.
The Red Cliffs Recreation Area trail head is the far side of the trail and one of the least used as a starting point. Head North on I-15 and take the Hurricane Exit 16. Follow Highway 9 to the light on 5300 W which coincides with the turn off for Quail Creek Reservoir. Follow 5300 West around the lake, it will T with Old Highway 91, go right. There is a sign for the Red Cliffs Recreation Area directing you under the freeway directly across from Harrisburg. Follow this in. You can park at the High Grade trailhead or continue a bit farther and park at the old building. The trail head is just across the road.
Riding the trail...
Seeing that Prospector is mostly a connector, riding it depends on what you are trying to do. Most commonly it is used to access Church Rocks from the Cottonwood Trailhead. In this case, head up the trail and at the T go left and follow the signs.
