Getting there

Wiley Falls sits about 5.8 miles north of Jarrettsville in Harford County. Navigate to the coordinates 39.68300, -76.51887, which mark the waterfall itself; the trailhead or parking area may be some distance away.

Open directions in Google Maps or Apple Maps, or view the map on the Wiley Falls listing. Navigation apps sometimes route onto seasonal forest roads, so check road status if you are heading into the mountains.

Nearly all of Maryland's well-known falls are on public land: state parks such as Swallow Falls and Cunningham Falls, and the C&O Canal National Historical Park at Great Falls, which charges an entrance fee on the Maryland side. Popular parks fill quickly on summer weekends and holidays, and some state parks close their gates once parking is full, so arriving early helps. The Potomac at Great Falls is one of the most dangerous stretches of river in the region, with powerful currents and hidden hazards; wading and climbing on riverside rocks have led to many drownings. In Garrett County, ledges are wet and slippery, and water is cold well into spring. Some Piedmont falls lie close to private property.

What to bring

This checklist is tailored to Wiley Falls based on what visitors report and the conditions typical of Maryland. For the complete list, see our waterfall hike packing guide.

• Offline map and coordinates. Save 39.68300, -76.51887 and download offline maps; cell service is often weak near waterfalls.
• Shoes with real grip. Rock near falling water stays wet and slick even in dry weather.
• Water and a snack. More than you think you need, even for a short walk.
• A light rain layer. Spray from the falls and quick-moving showers can soak you.
• Headlamp. In case your visit runs later than planned; check sunset time in the conditions panel above.

How to prepare

Timing

Spring is generally the strongest season for Maryland's falls, when winter snowmelt in Garrett County and frequent spring rains raise every stream. The Great Falls of the Potomac reflects rainfall over a vast upstream basin, so it can roar after storms in any season and runs especially high in late winter and spring. Summer brings lower flows and hot, humid weather, although Garrett County stays noticeably cooler. October is a fine month across the state, with fall color usually arriving first on the Allegheny Plateau and later in the Piedmont. Winter can coat Swallow Falls and Muddy Creek Falls in ice, but snow and freezing spray make paths treacherous.

Safety

Stay behind railings and off wet rock, never climb on the falls, and keep children within arm's reach near the water. Check the weather panel above for flood or storm alerts before you set out; water levels can rise fast after upstream rain. Our waterfall safety guide covers the most common hazards.

Respect the place

Pack out everything you bring, stay on established paths to limit erosion, and leave rocks and plants where they are. See Leave No Trace at waterfalls.

History of the area

According to the U.S. Geological Survey's naming record: Named for Matthew Wiley (1751-1840), the first of five generations of the Wiley family to own and operate the grain mills in the area

The federal gazetteer describes it this way: 100 ft high, approximately 860 ft. long; located along Falling Rocks Branch, 1.1 mi NE of Ivory Mill

Wiley Falls was entered in the Geographic Names Information System on May 12, 2011, and it appears on the USGS Norrisville 7.5-minute topographic map.

The U.S. Board on Geographic Names made a formal decision on its name on May 12, 2011.

Its neighbors on the map tell the story of the surrounding land: Falling Rocks Branch (stream, 0.2 mi), Jackson Branch (stream, 1.1 mi), Island Branch (stream, 1.7 mi), and Church Lane Spring (spring, 2.0 mi).

Potomac Fall Line and the Piedmont. The Great Falls of the Potomac is the state's signature cascade, a wide series of rapids and drops where the river crosses hard Piedmont bedrock and enters the narrow Mather Gorge. On the Maryland side it is part of the C&O Canal National Historical Park, with boardwalks to viewpoints and rugged riverside trails nearby; Stubblefield Falls and Yellow Falls are smaller named features in Montgomery County. In northeastern Maryland, Cecil and Harford counties hold modest falls on Piedmont streams. Gilpins Falls, near North East in Cecil County, sits beside a historic covered bridge, and other small cascades lie in wooded stream valleys near Jarrettsville and Rising Sun.
