Mackworth Island State Park
An island loop with rocky beaches and bay views the whole way
About this park
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.
Amenities
What visitors say
Synthesized from 510 Google reviewsReviewers consistently rave about the easy 1.25-mile loop, the constant water views, and the ranger-maintained shoreline access. A working pet cemetery on the island gives the visit 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.
Best for
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.
