Hiking in the Purgatory Falls: trails, map and practical info

Description

Purgatory Falls is one of those places in New Hampshire's Monadnock Region that punches well above its weight. At just 1.6 kilometers with 91 meters of elevation gain, this short trail leads to a genuinely impressive waterfall destination — the kind of spot that feels like a real discovery even though the hike itself is accessible enough for most fitness levels.

The Trail

The path to Purgatory Falls winds through dense New Hampshire forest that quickly feels removed from the surrounding countryside. The trail starts out mellow, following what was once an old woods road before narrowing into a more traditional footpath as you get closer to the water. Underfoot, you'll find a mix of packed dirt, roots, and increasingly rocky terrain as the falls approach. The forest canopy overhead is a blend of hardwoods and conifers, with ferns and moss covering the ground on either side of the trail.

The terrain is rated easy, and that holds true for most of the route. The 91 meters of elevation gain are spread out enough that the climb never feels demanding. That said, the sections closest to the falls get noticeably rockier, and the granite can be genuinely slippery when wet — so footwear with decent grip matters more here than the difficulty rating might suggest. Plan for about 45 minutes on the trail, though most people end up spending extra time at the falls themselves.

Upper and Lower Falls

Purgatory Falls is actually two waterfalls, and that's a big part of what makes this destination worth the trip. The Lower Falls come into view first as the trail opens up near the stream. Water moves over a series of granite ledges and drops into clear pools below. The area around the Lower Falls is relatively open, with flat rocks that work well as a natural rest stop. It's a comfortable, approachable spot — good for families or anyone who wants to take their time before pushing on.

The Upper Falls require a bit more effort, with a steeper and less formal path climbing alongside the stream from the lower area. The payoff is a more dramatic cascade where the water drops over taller ledges into a tighter, more enclosed gorge. The Upper Falls feel wilder and more secluded, with moss-covered boulders and a noticeable spray that keeps the air cool even on warm days. The contrast between the two falls — one open and social, the other intimate and rugged — gives the hike a satisfying arc that a single waterfall destination can't quite match.

The granite geology throughout both areas is worth paying attention to. Centuries of flowing water have carved smooth chutes and polished the rock into shapes that reward a closer look. The deep, still pools set against the white rushing water make for strong photography at both locations, in any season.

Wildlife and Forest

The forest around Purgatory Falls supports a solid variety of wildlife for such a compact trail. Common forest birds like chickadees, nuthatches, and woodpeckers are regulars along the wooded sections, while the stream corridor attracts species that prefer water nearby, including the occasional kingfisher or heron. Red squirrels and chipmunks are reliably present, and the mix of mature trees and younger growth creates layered habitat that benefits a range of species.

Near the falls, the combination of open light, flowing water, and diverse plant life draws butterflies and dragonflies during warmer months. The understory includes mountain laurel, which blooms in late spring, along with the ferns and moisture-loving plants that thrive close to the stream. The forest itself reflects New Hampshire's natural history — a mix of old specimens and younger trees that have grown in over time, creating the kind of varied woodland that rewards slow, attentive walking.

Seasons

Spring brings the highest water volume to Purgatory Falls, as snowmelt pushes the stream to its peak flow. The falls are at their most dramatic during this window, and the forest floor comes alive with early wildflowers and returning birds. Trail conditions can be muddy through the shoulder season, so waterproof footwear is a practical choice in April and May.

Summer settles into comfortable hiking weather, though water levels drop as the season progresses. The pools near both falls are at their most inviting during warm stretches, and the forest canopy keeps the trail shaded for most of the route. Fall transforms the surrounding hardwoods into the color display New Hampshire is known for, and the combination of foliage and moving water makes this one of the better short hikes in the Monadnock Region for autumn photography.

Winter is possible for hikers with the right gear — microspikes or snowshoes depending on conditions — and the ice formations that build up around the falls in cold snaps are genuinely striking. The trail becomes more technical in winter, so experience with cold-weather hiking and appropriate footwear are both important before heading out between December and March.

What to Bring

Sturdy hiking shoes with good grip are the most important item on the packing list, particularly for the rocky terrain near both waterfall areas. There are no facilities along the trail, so carry enough water for the full outing and bring snacks or lunch to enjoy at the falls. A map or downloaded GPS track is worth having, especially if you plan to explore beyond the main waterfall areas — the forest feels more remote than the short distance from the trailhead might imply.

The falls and surrounding ecosystem are sensitive to heavy foot traffic, so staying on the marked trail and keeping off the natural rock formations around the pools helps preserve the experience for everyone who follows.
