About a 900ft vertical gain on the way up to this beautiful alpine lake, but it's not a super long hike. We stopped a lot, and got back within 3 hours. Most people were faster than we were! It's busy on weekends, but you will still have space to yourself. At the lake everyone has to take turns going out on the dock. You can bring a small picnic and hang out there, but there is no fishing, no boating, and the plants around the lake are fragile, so you have to use the walkway. Just before you get to the lake, there's a huge meadow that is probably a resting place for Elk in the fall. Going back is much easier, most of your vertical gain is done! Enter the area by the Arapaho Bay entrance to Lake Granby. Pass over the dam. You have to park on the side of the road. There is no trail sign. Recommend GPS. Beautiful views of Lake Granby as well. read more
