Access Club Lake trailhead from the Morraine park in RMNP. This is a bit of a tricky hike. It seems easy at first but suddenly gets really steep(uphill) and really rocky. Footing is loose and fairly difficult. The hike is 3.5 miles and climbs up out of the morraine into the forests over about 3 miles: significant elevation gain, then at the last half mile, descends steeply into the Headwaters of the Big Thompson gorge at a local called The Pool. From the Pool you can circle back to your beginning location in about 2.5 miles. Cub Lake is a great perched(& beaver damned) lake & we have seen moose here twice. This hike is harder than many in the park — give yourself lots of time and bring lots of water!!! It is worth it!!!
