Calais Ridge Fire Tower Circuit
Three fire towers across Washington County ridges
Calais Ridge Fire Tower Circuit links three Depression-era fire towers across 24 miles of Washington County’s most rugged terrain, offering commanding views of Passamaquoddy Bay and the Canadian Maritimes. The route follows abandoned CCC roads built in the 1930s, climbing Devil’s Head Mountain (elevation 1,424 feet) where the restored steel tower provides 360-degree views spanning from Mount Katahdin to Grand Manan Island. Rocky ledges and steep grades challenge drivers between Baring Hill and Red Beach Mountain towers.
This is a difficult trail demanding experienced 4WD operation and rock sliders for the granite ledges on Devil’s Head approach. Mud season (April-May) makes sections impassable. Best run July through early October when blueberries ripen along the ridgelines. No permits required but notify border patrol if camping near the Canadian boundary. Primitive sites exist near each tower, though water must be packed in. The payoff is some of Maine’s most spectacular border country vistas and genuine fire tower history.

Frequently asked questions
Can a stock Jeep Wrangler or 4Runner run this trail, or do I need a built rig?
A stock Wrangler Rubicon can get through, but rock sliders are the hard minimum — Maine's ledge rock will peel rocker panels off an unprotected rig fast. Lift and all-terrain tires are strongly advised; a bone-stock daily-driver 4WD is going to have a bad time on the technical sections.
When does the trail become impassable, and can you run it in spring?
Best window is July through October. Spring is a hard no — Maine's frost-heave cycles leave the rock sections unstable and the access roads are typically closed or gated by the Bureau of Parks and Lands through mud season. First heavy snow in late October or November shuts it down for the winter.
Do I need a permit to run this trail or camp along it?
No permit is required to drive the trail, but dispersed camping is managed by Maine Bureau of Parks and Lands — follow Maine's Leave No Trace guidelines and don't camp within 200 feet of water. No fees at the time of writing, but check with the Bureau before you go since land-use rules in Washington County backcountry can change.
What's the hardest section and what actually makes it technical?
The exposed granite ledge climbs connecting the ridge between the second and third fire towers are where rigs get stuck — off-camber shelf rock with no room to correct if a tire slides. Ground clearance matters less than tire placement and slow throttle control; it's not a power problem, it's a precision problem.
How far is the nearest gas station from the trailhead, and is there water on the trail?
Calais has fuel and is your last reliable stop — top off before you leave town, there's nothing out on the circuit. Don't count on finding clean drinking water on trail; carry everything you need for two days, as surface sources in Washington County backcountry should be filtered before use.
