Arapaho National Recreation Area

30,690 acres



On the west side of Rocky Mountain National Park are the first of many dams across the Colorado River forming several lakes around Granby, Colorado.  Arapaho National Recreation Area contains five reservoirs, the largest of which is Lake Granby (but not including Grand Lake and Shadow Mountain Lake).  Also nearby, Monarch Lake is the starting point for multiple trails into the Indian Peaks Wilderness.  Despite its proximity to the Denver metropolitan area, this untamed country is home to a variety of wildlife including moose, martens, and mountain lions, as well as the river otter and ouzel (or dipper) we saw during our January visit.

Must-Do Activity

The largest reservoir in Arapaho National Recreation Area is Lake Granby, an area popular with snowmobilers and ice fisherman in the winter.  Summer is also a good time to visit when the lakes are unfrozen and available for boating, swimming, and other water sports.  That’s when backpackers on the Continental Divide National Scenic Trail prefer to come through here.

Best Trail

Snowshoers looking for some quiet can drive to the eastern end of Lake Granby and hike a mile to Monarch Lake on a road that is closed during the winter months.  Throughout the year, Monarch Lake is the starting point for multiple trails that climb into the high elevations of the Indian Peaks Wilderness, plus the Continental Divide National Scenic Trail.

Peak Season



During the summer, day-use fees apply at portions of Arapaho National Recreation Area, like Monarch Lake and boat launches.

Road Conditions

The road back to Monarch Lake and many others are closed seasonally due to heavy snow accumulations.


Campgrounds on the lakes fill up in the summer and even the dirt roads around the west entrance to Rocky Mountain National Park can be jam-packed with dispersed campers.

  1. I never thought to visit Monarch Lake in the winter… now I’m going to have to check it out. It looks so pretty all covered in snow. I love this area! So many great hikes.
