Quarry Lookout via Brownsville Trail climbs 229 ft across 3.7 miles, averaging 62 ft of gain per mile — a gentle grade. It's an out-and-back: 1.9 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.

The route follows the Brownsville Trail for its main stretch.
When to go
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 3,046 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
