About Whetstone Falls
Whetstone Falls is a quiet, scenic cascade tucked into Maine’s forested landscape, popular with hikers who want a peaceful outing away from busier trailheads. The falls themselves make a rewarding destination — a compact, photogenic drop set among mossy rocks and northern hardwoods that offers a restful place to linger and listen to the water. The most common approach is a 2.4-mile out-and-back trail with roughly 350 feet of elevation gain, rated moderate, that winds through forest to the waterfall viewpoint. There isn’t developed camping immediately adjacent to the site; the nearest developed camping and hut options are at Katahdin Woods and Waters National Monument, about 32.1 km (roughly 20 miles) from the trailhead, so plan overnight logistics accordingly.
The Setting
Whetstone Falls sits at 371 feet along the East Branch Penobscot River, in the coastal lowlands of Maine.
Trail & Hike Details
Trail Description
Route: 2.4-mile out-and-back; Elevation gain: ~350 ft; Difficulty: Moderate. The trail follows a forested footpath and leads steadily toward the falls over rolling grades — expect short climbs but no extended steep sections. Underfoot the tread can be muddy or uneven in places, so sturdy footwear is recommended; the pace is suitable for hikers with moderate fitness looking for a relatively brief day hike.
What to Expect
Dogs are welcome.
Accessibility
The trail is not wheelchair accessible. Uneven terrain and elevation changes require steady footing.

How we calculate this
This is a transparent outlook, not a precise forecast. We take the waterfall's current flow strength (how it ranks against its historical normal for today, from the nearest USGS stream gauge), carry that ranking forward along the gauge's seasonal curve, and nudge it for forecast rain. Confidence is highest for the next day or two and falls further out. Always check official conditions and your own judgment before visiting — high flows can be dangerous.

Weather Forecast
The Terrain, Seen by LiDAR
Aircraft-mounted lasers measured this ground to within inches. Trees and buildings are digitally stripped away, leaving the bare shape of the land the water has carved.
The bare-earth surface loses about 69 feet through the falls, but gradually, the profile of a cascade rather than a plunge. The ground at the falls is roughly 359 feet above sea level.
The ground changes about 50 feet in the 500 feet above the falls and 13 feet in the 500 feet below. Facing west, the falls glow in afternoon and evening light.
