RMNP Thunder Lake Boulder Grand Pass

A 6.8 mile hike to beautiful Thunder Lake. From there continue on to the Lake of Many Winds and the Continental Divide at Boulder Grand Pass. A full day strenuous hike of 17+ miles round trip.

Start at the Wild Basin Trailhead in Rocky Mountain National Park. Take the trail past Calypso Cascades and Ouzel falls. Take the short spur to admire Ouzel Falls. Back on the trail you will come to a junction where the trail splits – left to Bluebird Lake, and Right to Thunder Lake. Eventually the trail opens up to a big meadow. The trail circles around the lake on the right. From here you are climbing much steeper now, up to the continental divide. At the base of Boulder Grand Pass is Lake of many winds. Climb the scree field up and take in the amazing view.
