Short on effort, big on payoff. This gorge-floor stroll threads between sheer Black Hand sandstone walls that rise nearly 200 feet, with ferns, hemlock, and constant trickles painting the rock. It’s an out-and-back totaling about 1.1 miles (round‑trip), ending at a delicate waterfall and pool. Expect cool, dim light even at midday—sunlight struggles to hit the valley floor—so it’s a refreshing choice in warm weather.
The route is generally easy with minimal elevation (~75 feet total). Much of the first half-mile is paved or on wide boardwalks with railings. Past that, a short natural segment (dirt, sand, rock) leads to the falls; low spots can hold standing water after rain, and there’s a slump-block obstacle near the turnaround. If you prefer to keep things fully accessible, the paved/boardwalk portion alone still delivers classic gorge scenery.
This is a study in sandstone and shade: narrow canyon walls, moss-draped recesses, and lush understory. Highlights along the way include the Grotto, Slump Rock (a massive fallen block tucked into the gorge), and the waterfall at the headwall. Keep an eye out for cross‑bedded sandstone, honeycomb weathering, and the gorge’s tight pinch points that concentrate the cool, damp microclimate.
The first stretch is the most wheelchair- and stroller‑friendly; beyond the boardwalk, footing turns uneven to the falls. You’ll find a paved parking lot with designated van‑accessible spaces and flush restrooms near the trailhead. No drinking water is available on site.
Year‑round good. March–November is especially scenic, with spring flow and fall color adding flair. Summer stays surprisingly comfortable thanks to constant shade and spray. Winter can be spectacular with icicles—just plan for potentially icy surfaces. Aim for early morning or late afternoon for softer light filtering into the gorge.
This is a state nature preserve with stricter rules: no pets, and stay on designated trails to protect sensitive plants and soils. The preserve is open from half an hour before sunrise to half an hour after sunset. The hollow takes its name from W. J. Conkle, who carved his inscription here in 1797; today, the same cliffs and headwall remain the showpieces.
Park at the main Conkle’s Hollow lot on Big Pine Road (paved, with designated van‑accessible spaces) next to the flush restrooms.
Boardwalk and rocks stay damp and slick; expect standing water or mud after rain, icy patches in winter, and a slump‑block obstacle near the end. Stay on designated trails and note that pets are not permitted.
