So, forget the trails. Someone else can review that. I'm here for floating down the river, which is one of the most fun, free summer activities that you'll find in the Portland area.
When you're bored on a summer's day, grab a friend and head to Walmart for tubes and a few beers (in cans, of course). Take two cars. You can drop one car off after the bridge on Allen Ave Extension (a couple miles after the intersection with Washington Ave). Take the other car to the sandy parking lot before Hannaford in West Falmouth that's on the river. This is where I use for the entry point.
The next three hours are absolute perfection. Floating down a mild current, bright sun beaming on your face and complete silence besides nature. The water is warm, somehow, even early in the season. It's a fairly wide river and very deep (yeah I may be the loser who wears a life jacket...I blame that on my parents for not investing in swimming lessons!). There's also rope swings at various points that you can jump off.
After about two hours, you'll see signs warning of dangerous rapids and it will scare the living **** out of you. That's the time to head to shore and walk the trail for a few minutes. The signs aren't joking and I'd love to see a kayaker navigate those serious rapids. Hop back in the water after and keep relaxing until you reach the dock, which leads up the hill to your first car.
I hope too many people don't discover this river because it's been so peaceful the last few summers. But it really is a great group activity and I'd highly recommend it if you want a break from the usual beaches/lakes. read more
