Big Rock Falls on the Mill Prong route
Big Rock Falls is a wooded cascade on Mill Prong in Shenandoah National Park. Plan a waterfall hike rather than assuming the pool will be deep, clear or suitable for swimming when you arrive. Mossy rock, forest and the nearby Rapidan Camp route are the main reasons to explore this area.
Start at Milam Gap
Use Milam Gap parking at Skyline Drive mile 52.8. Cross the road, briefly follow the Appalachian Trail, then turn left onto blue-blazed Mill Prong Trail. At the second stream crossing, stay right onto the yellow-blazed Mill Prong Horse Trail toward Rapidan Camp. Follow current trailposts and carry a park map.
Falls visit or full Rapidan Camp hike?
NPS rates the full Rapidan Camp out-and-back as moderate: four miles round trip with 870 feet of elevation gain. Those figures describe the camp outing, not a measured waterfall-only trip. Stream crossings may become difficult after rain. Turn around if crossing conditions are beyond your ability, and allow time for the uphill return.
Swimming expectations
NPS permits swimming in park streams generally, but warns that many are rocky, shallow and cold even in summer. This does not certify a particular pool as safe or establish its water quality. Never climb on or around waterfalls. Avoid jumping, diving and fast-moving water; changing flow can make a previous visit or photograph a poor guide to present conditions.
Practical planning
A park entrance fee applies. Bring drinking water and footwear with traction; do not depend on unconfirmed amenities at the trailhead or falls. Check park alerts before driving Skyline Drive. Rapidan Camp adds a history stop, but allow for the full hike if continuing there.

Getting There
Start at Milam Gap parking, Skyline Drive mile 52.8. Cross Skyline Drive and briefly follow the Appalachian Trail to the trailpost. Turn left onto blue-blazed Mill Prong Trail. At the second stream crossing, stay right onto the yellow-blazed Mill Prong Horse Trail toward Rapidan Camp. Follow current trailposts and the NPS map. Stream crossings can be difficult after rain; turn around if unsafe. The four-mile round-trip distance published by NPS is for the full Rapidan Camp hike, not a waterfall-only measurement.
Quick Navigation
Access Notes
Access is via the Milam Gap trailhead, not a drive-up waterfall. Follow current park alerts and trail signs. Stream crossings can become difficult after rain.
