Maine is one of the best states in the country for hiking with dogs. Most trails welcome leashed dogs, many preserves allow off-leash hiking under voice control, and the terrain offers everything from flat coastal paths to mountain summits where your pup can cool off in a stream on the way down.
Here are the best trails for hiking with your dog in Maine, along with the leash rules and tips you need to plan a great outing.
Best Coastal Trails for Dogs
Mackworth Island, Falmouth
Distance: 1.5 miles loop | Leash: Required
A flat loop around a small island in Casco Bay with ocean views the entire way. Dogs love the shoreline access at low tide, and the trail is wide and easy on paws. This is one of the most popular dog-walking spots in Greater Portland for good reason.
Wolfe’s Neck Woods State Park, Freeport
Distance: 2.0 miles of trails | Leash: Required (6 ft max)
Shaded forest trails along Casco Bay with rocky beach access at several points. The trails are gentle and well-maintained, and the tall pines keep things cool on hot days. Dogs can wade in the shallow coves at low tide.
Reid State Park, Georgetown
Distance: Beach walking (variable) | Leash: Required
Reid has two long sand beaches separated by rocky headlands. Dogs are allowed on the beach year-round, though they must be leashed. The firm sand at low tide makes for excellent walking, and most dogs go wild for the waves.
Rachel Carson NWR, Wells
Distance: 1.0 mile loop | Leash: Required
A flat, easy loop through salt marsh. Dogs must stay on the trail (no wading in the marsh), but the birding and scenery make it a pleasant walk for both of you.
Best Mountain and Forest Trails for Dogs
Bald Rock Mountain, Lincolnville
Distance: 2.0 miles round trip | Leash: Recommended
A gentle climb to open ledges with wide views of Penobscot Bay. The trail is not steep enough to trouble any reasonably fit dog, and the summit ledges make a great spot to rest and take in the view together. Bring water, as there are no streams on this trail.
Pleasant Mountain, Bridgton
Distance: 3.5 miles round trip (Ledges Trail) | Leash: Recommended
The Ledges Trail climbs through forest to open granite slabs with views of the Lakes Region and the White Mountains. Dogs handle this trail well, though the exposed ledge sections can be hot on paws in direct sun. Start early on summer days.
Mount Agamenticus, York
Distance: Multiple trails (1-4 miles) | Leash: Required on some trails, check signs
Mount Agamenticus has a network of trails through varied terrain, and it is one of the most dog-friendly hiking areas in southern Maine. The summit has wide views and a learning lodge. Several trails pass streams where dogs can drink and cool off. The Big A Trail to the summit is the most popular route.
Bradbury Mountain State Park, Pownal
Distance: 2.0 miles loop | Leash: Required (6 ft max)
An easy climb to a summit with views toward Casco Bay. The trail is short and well-graded, making it a great option for dogs new to hiking or older dogs that cannot handle long distances anymore. The shaded forest keeps things comfortable in summer.
Gulf Hagas, Brownville
Distance: 8.0 miles loop | Leash: Recommended
For experienced hiking dogs, Gulf Hagas is the “Grand Canyon of Maine” with waterfalls, deep gorges, and swimming holes. The trail is rugged and rooty in places, so this is best for dogs that are comfortable on rough terrain. The swimming holes along the Pleasant River are the highlight for water-loving dogs.
Tumbledown Mountain, Weld
Distance: 5.5 miles loop | Leash: Not required
Tumbledown’s alpine pond at the summit is one of the best dog swimming spots in Maine’s mountains. The Brook Trail is the easiest route up and follows a stream the whole way. The summit pond is clean and clear, and dogs who love water will not want to leave.
Dogs in Acadia National Park
Acadia allows dogs on most trails, but there are important restrictions:
- Dogs must be leashed at all times (6 ft max)
- Dogs are prohibited on ladder/rung trails (Precipice, Beehive, Jordan Cliffs)
- Dogs are prohibited on Sand Beach from June 15 through September 15
- Carriage roads are excellent for dogs and cover 45 miles of crushed stone paths
The carriage roads around Jordan Pond and Eagle Lake are the best options for hiking with your dog in Acadia. They are wide, shaded, and relatively flat.
Tips for Hiking with Dogs in Maine
Ticks are a serious concern. Maine has one of the highest Lyme disease rates in the country, and dogs are just as vulnerable as humans. Use a veterinarian-recommended tick preventive year-round, and check your dog thoroughly after every hike. Pay close attention to ears, armpits, and between toes.
Bring enough water. Dogs overheat faster than people, especially breeds with thick coats. Carry at least 8 oz of water per mile for your dog, and bring a collapsible bowl. Many Maine trails pass streams and ponds, but do not count on it.
Watch for porcupines. Porcupines are common in Maine forests, and a curious dog can end up with a face full of quills. Keep your dog close on narrow trails and be especially cautious at dawn and dusk.
Hot granite hurts paws. Maine’s exposed granite summit slabs can get extremely hot in direct sun. If the rock is too hot for your palm, it is too hot for your dog’s paws. Hike early or late on sunny days.
Pack out waste. Bring bags and carry out your dog’s waste. Leaving it on the trail, even off to the side, is not acceptable. Many trailheads have waste stations, but do not rely on them.
Know your dog’s limits. A 10-mile mountain hike is not appropriate for every dog. Start with shorter, easier trails and work up to longer distances. Watch for signs of fatigue, limping, or excessive panting, and be willing to turn around early.
