Mackworth Island State Park
An island loop with rocky beaches and bay views the whole way
About this park
Mackworth Island State Park sits on a 100-acre island in Falmouth connected by a short causeway, with a 1.25-mile dirt loop trail that hugs the shoreline of Casco Bay the whole way. Leashed dogs are welcome, and short side paths drop down to small rocky beaches and a children's fairy village in the interior pines.

Mackworth Island State Park reviews
What visitors consistently sayReviewers return to the same three things: the easy 1.25-mile loop, the constant water views, and how well maintained the trail stays. A working pet cemetery in the island's interior gives Mackworth Island a quiet character that regulars remember.
A mix of Falmouth regulars, Portland weekenders, and out-of-state visitors. Sunrise and late-afternoon walks pull a calmer dog crowd; midday in summer skews tourist-heavy.

Before you go
Strict leash rule; rangers enforce. Parking caps the visitor count and the lot turns cars away when full, so arrive before 10am on a summer weekend or come on a weekday. Maine residents enter free; non-residents pay $4 per adult at the gate.
Frequently asked
- Can dogs be off leash on Mackworth Island?
- No. This is a state park, and the leash requirement holds the whole way around the loop. Reviewers describe it as a leashed-dog walk rather than a place to let a dog run.
- Is there an entry fee?
- Reviewers report a fee collected at the gate, with Maine residents admitted free and non-residents paying $4 per adult.
- How long is the loop and how hard is it?
- About 1.25 miles of flat, well-maintained dirt path around the shoreline. Reviewers call it an easy stroll, with benches and picnic tables spaced along the way.
- What is parking like?
- The lot is small and caps the number of visitors on the island. Reviewers report cars being turned away once it fills, so an early arrival or a weekday visit is the reliable way in during summer.
- Can dogs get down to the water?
- Yes. Short side paths branch off the loop to small rocky beaches, giving leashed dogs shoreline access at several points along Casco Bay.
