From the Wild Basin parking area, head out west on the trail on the north side of North St. Vrain Creek. The trail passes Copeland Falls after .3 mile and continues another 1.2 mile to an intersection. This first section of trail has little elevation gain on a wide and heavily used trail. At 1.5 mile from the TH, head up left for .3 mile to Calypso Falls and join another trail. This new if taken east will lead back east to meet the Finch Lake trail. Instead, head west to Ouzel Falls in .9 mile and continue left at another trail junction in another .4 mile. Now you'll be heading for Ouzel and Bluebird Lakes. The trail switchbacks up the hillside and gains a broad and open ridge. Follow the trail past the turnoff for Ouzel lake (1.4 mile from the last intersection) and continue another 1.8 mile to Bluebird Lake. Most of the trail after gaining the open ridge gains elevation gradually, but as you approach the last half mile to the lake, you'll have some steeper sections. Copeland Mountain will offer a formidable north flank seen across the valley to the south.
All camping in the RMNP backcountry is regulated and the campsites are designated and sites are limited. Visit the RMNP website for the most current information on backcountry camping. On the Bluebird Lake trail, there is a designated site near Ouzel Lake and then about a half mile before arriving at Bluebird Lake. Camp locations last time we utilized this system could be made as early as the month of March, preceding the summer of your intended visit. Get your application in as early as possible to have any chance of getting your desired campsite. The following link takes you to a pdf map of all the designated backcountry sites.
The Bluebird Lake campsite has a few tent spots located on a shelf above a bluff that overlooks the trail. There are low conifers there. There is a sign marking the turnoff for the campsite. Water can be obtained from the nearby Ouzel Creek and there are nice wildflower meadows to visit. The coordinates below are our best guess as to the campsite location using Google Earth.
