Loved it! We branched off to the Rawah Trail and then then Twin Crater Lakes. We went at the end of June and there was still a lot of snow up by Crater lakes. On West Branch Trail you have to cross the river. I really wish I would have had my Tevas!!
Jeff A. on Rawah Trail
the first several miles are pretty steep then it levels out à bit with many miles of stunning alpine lakes stand and summiting opportunities perfect for camping and hiking and the are tons of brookies in the crystal clear streams. there are large trout in the pond and lakes
I backpacked a ~20 mile loop that connects the West Branch Trail to the Rawah Trailhead. Highly recommended for the route's excellent scenery, 10+ lakes along the trail, and a good summit about halfway through. This hike can be looped in either direction, and completed in 1-2 nights, or as a long day hike. Begin at the Tunnel Campground at Roosevelt National Forrest just outside of Fort Collins down Poudre Canyon.
I attached a link to the trail route.
