Boulder Cave trail is a highly used trail leading to the cave. The trail is dirt and becomes rougher as you descend into the canyon at the cave entrance. From the parking area the trail leads uphill for approximately 3/4 of a mile. The hardest part of the hike is walking up the trail from the cave exit.
Recent high water washed a lot of material off the cave trail and left it rough. Don't attempt going through the cave without a flashlight and watch your step.
