Between the Connecticut River and the Green Mountains, the Appalachian Trail passes through high, rugged country with woods and overgrown farmlands. From “Maine Junction” (near U.S. 4) south, the A.T. follows about one hundred miles of the famed “Long Trail” along the rugged crest of the Green Mountains.
The Trail approaches treeline at Killington and Stratton mountains, and parts feature strenuous ascents. But, in general, Vermont hiking crosses varied terrain, at lower to mid-range elevations with a fair amount of elevation gain and loss. It passes through forests of paper birch and white pine, wooded mountains, and farm valleys. Some overnight sites charge a fee.
Avoid Vermont trails in “mud season,” mid-April through Memorial Day. Hiking there in wet, sloppy conditions leads to serious Trail erosion.

When to go June through September. Avoid Vermont trails in “mud season,” mid-April through Memorial Day.
Vermont was a visually stunning state in many places. Also, the mountains there began to pose quite a challenge. Thru-hikers nickname the state “Vermud” because there are many places along it’s length where the trail turns into a giant mud pit. However, because I was there in September, the mud was mostly dried up
