This trip will blow your mind. A long loop backpacking trip that circumnavigates the interior of Rocky Mountain National Park (images). It includes off-trail travel, some class-3 climbing up the back of Longs Peak and a chance for a very unique and remote trip in with a very popular National Park. This is a high adventure, difficult trip for strong backpackers.
You will need to get your backcountry camping permit from the Rocky Mountain National Park Backcountry Office. The permit application is found of page 7 of the national park’s brochure. You’ll need the following campsites in this order: (92) Renegade, (84) South Meadow, (68) Lake Verna, (48) Hunters Creek, (38) Boulder Brook. As with all national parks, they limit the group size to 6. You may have to get creative if sites are unavailable or your group is larger.
Starting from Bear Lake Trailhead you head up and over Flattop Mountain to Renegade Campsite.The trip totals 43.4 miles during which you’ll circumnavigate the park in a counterclockwise fashion. A short stretch along the road at the north side of Grand Lake will quickly put you back in the woods. You can also resupply here if you need to. Take note of the off-trail sections on the topo maps that are denoted by the dashed lines.
