Squam Swamp - Squam Swamp Interpretive Trail is a 1.7 mile out and back trail located near Nantucket, Massachusetts and is rated as moderate. The trail is primarily used for hiking and is accessible year-round.
Not very impressed. Most of the maps for Montauk and Nantucket only show a marker for possibly the trail head but doesn't provide the actual trail.
It's not near Nantucket, it's on Nantucket. Near Nantucket would be in the Atlantic Ocean. It's a "lollipop trail"- that is there's a loop that starts a little ways out from the trailhead. There's a connector trail off the loop that goes to Squam Farm and more trails. I would rate it as EASY since there's almost no elevation variation. There should be interpretive brochures at the trailhead box. If not, check with the Nantucket Conservation Foundation.
