Lye Brook Falls via Lye Brook Trail climbs 857 ft across 4.5 miles, averaging 190 ft of gain per mile — a gentle grade. It's an out-and-back: 2.2 miles each way, and you get a second look at the same terrain on the descent.
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 route starts from a mapped parking area. Trailhead lots here are small — often a dozen cars or fewer — and the popular ones fill by 9am on summer weekends and through foliage season. An early start is a parking strategy as much as a weather one.
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
Lye Brook Falls is the destination. Waterfalls run hardest on spring snowmelt and after summer thunderstorms; by late season a cascade that looked spectacular in photos can be a trickle.
The route follows the Lye Brook Trail for its main stretch.
When to go
Topping out at 1,595 ft, this one stays below the 2,500 ft mud-season line, so it dries out earlier and is a reasonable choice in late spring when the high ground is still off-limits.
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
