    Route Description for Rattlesnake Lake Trail

    The shore of Rattlesnake Lake is an ideal spot for family fun, and walking the Rattlesnake Lake Trail gives you a nice chance to stretch your legs and enjoy a wide view of the lake. You can take this walk if you’re just here to hang out on the lakeshore, or you can use it as a warm-up or cooldown for the popular nearby Rattlesnake Ledge Trail, which climbs to a ledge overlooking the lake and the nearby mountains. Enjoy this walk with little ones or just take it by yourself for a nice little break in nature.

    The trail begins near the Cedar River Watershed Education Center. Walk towards the lake and take the path on the lakeshore, heading to your right. Walk along this pathway, perhaps heading right to the water’s edge at welcoming spots. There’s a pretty photo spot around ¾ of the way down the path, a few steps before the boat launch. You might be able to spot boaters on the lake, maybe casting their lines or just enjoying the water.

    The path ends shortly after the boat launch, so you can loop back and retrace your steps along the shore again. Why not plan a picnic lunch or grab a book to keep enjoying the area? If you’re headed to Rattlesnake Ledge next, go to the end of the trail, pass the restrooms and parking lot, and pick up the trail at the marked trailhead.

    Hiking Route Highlights

    Rattlesnake Lake

    Back in the early 1900s, the town of Moncton stood around the northern shore of Rattlesnake Lake. This town was destroyed by flooding in 1915, and nothing remains of the town. While that somewhat dark history exists, today the area is enjoyed by adventurers all year round. The lake is a popular fishing spot and the hike to the overlooking ledge is enjoyed by many throughout the year. The shore is also used for slacklining and picnicking.
