Rattlesnake Gulch Trailhead.
Rattlesnake Gulch Trailhead provides access to the Fowler Trail and Rattlesnake Gulch Trail in Eldorado Canyon State Park, Colorado. The infrequently-visited Eldorado Mountain is most commonly approached from this trailhead as well.
From Boulder, take Hwy 93 south approximately 3 miles to Hwy 170. From Denver, one can take Hwy 93 north to Hwy 170. Take Hwy 170 east to the town of Eldorado Springs. Continue through Eldorado Springs to the entrance of Eldorado Canyon State Park. Pay your fee, then continue on Hwy 170 for 0.5 miles until you see the Rattlesnake Gulch Trailhead parking area on the left side of the road.
Camping is not allowed at the trailhead, nor is drinking water available. There are no toilets.
