TRIP LENGTH: 8.5 miles (from the East End Beach round-trip)
HIGHLIGHTS: Check out Presumpscot Falls, swim in the river, bird-watch in the estuary, ride the tides in and out of the river.
The Presumpscot River flows into Casco Bay about one mile from the East End Beach. With the right timing, you can ride the flood tide upriver and cruise back out with the ebb. Paddling up the Presumpscot allows you to experience three very different environments: The open waters of Casco Bay, the wildlife-rich salt marsh of the Presumpscot River Estuary, and the narrow, densely-wooded river gorge where you'll find roaring Presumpscot Falls.
