About this trail
In Green Mountain and Finger Lakes National Forests, Vermont, Castle Brook (USFS trail TER-381) covers 8 mi of National Forest System trail. The figures here are pulled from the official US Forest Service trail data for Green Mountain and Finger Lakes National Forests, covering the trail's mileage, tread, grade band, and the bike and e-bike uses the agency lists as designated. USFS records list its surface as native material. Based on slope, this is a Easy trail (grade band 5-8%); that reflects gentle gradient and is not the same as a technical MTB difficulty rating. Bike use is designated as allowed, typically Jun–Oct. The agency lists no Class 1, 2 or 3 e-bike designation here; absent a local order to the contrary, that means e-bikes are not an allowed use on this trail. The route is mapped as USFS Trail Class 4 on the agency's 1-to-5 development scale, where 1 is the most primitive, minimally maintained tread and 5 is the most developed. Because conditions, closures, and local orders change between data refreshes, confirm the current status with the managing ranger district before you ride.
