Concord River is a 6.5 mile trail located near Concord, MA. The trail is primarily used for canoeing and is accessible from April until October.
A fantastic place to Kayak. If you own your own kayaks, there is a boat ramp on Lowell Road, just a half mile north-west of Concord center. There are also places that will rent kayaks to you and they will, of course, get you in the water as well.
If you've never kayaked before, try one of the rental places. If you enjoy it, and there's a good chance that you will, and think you might want to Kayak regularly, it might be worth investing in kayaks of your own if you have the means (can afford kayaks and roof racks, and can put kayaks on car or SUV and take them off as needed).
Took kayaks out on the river last Sunday. Used the Carlisle ramp. Really easy to get to, plenty of parking....wasn't too busy. Pushed the kayaks in and went downstream (though there is barely a noticeable current). Went about four miles and almost made it to the historical North Bridge, but had to turn back because of mean thunderclouds we saw heading our way. Water temp was awesome! Slightly cooler than bath water temp. Saw geese, cranes, lots of dragonflies, and them furry swimming beavers (not sure if they are true beavers, but that's what I call them. Lol). Did not come across any "beach" for swimming. Close to the shores of course it was very muddy, and lots of Mosquitos. River is wide, so no need to get near them. On the water we also saw other boats, powered and unpowered, and a jet ski. Max speed posted was 10mph. Everyone was courteous and slowed their powered boats to a crawl when around kayaks.
