Plan this routeHow hard is Forehead Bypass and Long Trail Loop?
Forehead Bypass and Long Trail Loop climbs 870 ft across 1.6 miles, averaging 544 ft of gain per mile — steep enough to be a workout in the classic New England style. It runs as a loop, so the return leg covers new ground rather than retracing the climb.
RidgeSync estimates moving time from the trail-snapped geometry and the real elevation profile rather than a flat miles-per-hour figure, which is why the estimate below is usually slower than a generic hiking calculator on steep New England tread.
Trailhead, parking and water
The start point is a trail junction rather than a formal lot, so check parking before you commit: roadside pull-offs are frequently posted, and town roads near trailheads are often unplowed or seasonally closed.
No mapped water sources sit within 0.75 mi of this route, so carry what you need for the full distance — generally two liters for a half day, and more in summer heat.
What you'll see
The route tops out at The Forehead at 3,901 ft. Summits vary more than elevation suggests — some are open ledge with a full ridge view, others are wooded with a fire tower doing the work — so check what the top actually offers before counting on a view.
The route follows the Long Trail for its main stretch.
When to go
The high point sits at 3,901 ft, which puts the upper section above treeline. Stay on rock and marked tread near the summit: the arctic-alpine plants up here survive in a few acres statewide and don't recover from being walked on.
Green Mountain Club and Vermont Forests, Parks & Recreation ask hikers to stay off trails above 2,500 ft during mud season, roughly mid-April through Memorial Day. This route tops out at 3,901 ft, so it falls squarely under that request — a request rather than a closure, and widely respected. The tread is genuinely fragile when saturated, and this is the easiest way to damage a trail.
Late September through mid-October is the best window here: firm trail, no bugs, and the clearest air of the year. The dependable season runs late June through mid-October. Winter turns the steeper pitches into a traction problem — microspikes are the minimum, and north-facing sections hold ice well into spring.
Regulations and Leave No Trace
- Vermont asks hikers to stay off trails above 2,500 ft during mud season (roughly mid-April to Memorial Day) — this is a request, not a closure, and it is widely respected
- Dispersed camping on state land is generally legal below 2,500 ft, at least 200 ft from water and trails; the Green Mountain National Forest has its own rules and some areas are posted
- Campfires are prohibited at many Long Trail and Appalachian Trail sites — carry a stove and check the site before planning around a fire
- Dogs are allowed on most Vermont trails but must be under control; some summits with fragile alpine vegetation ask that dogs stay leashed
- Pack out everything, including food scraps and toilet paper — Vermont soil is thin and slow to break anything down
