Plan this routeHow hard is Castle Hill via Cobb Hill Road?
Castle Hill via Cobb Hill Road climbs 387 ft across 1.9 miles, averaging 204 ft of gain per mile — a gentle grade. It's an out-and-back: 1 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 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 Castle Hill at 924 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 Cobb Hill Road for its main stretch.
When to go
Topping out at 924 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
