Dogs are welcome at Two Lights State Park on Maine's legendary rocky coast. Named after twin lighthouses constructed in 1828 down the road from the park, Two Lights State Park spans 41-acres of rocky headlands, including outcrops and grassy areas where you can have a picnic with a view. There are a number of pet-friendly trails that weave around the park, showing you and Fido the best of Maine's coastal beauty. Dogs are welcome on a leash under six feet, as long as owners clean up any mess after them. Two Lights State Park is open every day of the week from 9am until sunset.
