This week I hiked to Odessa Lake in Rocky Mountain National Park, a place I’d never been before. The hike starts at the Bear Lake trailhead, passing Lake Helene, and ending up at Odessa Lake. It is a beautiful but challenging 8 mile RT hike.
The first part of the trail follows Bear Lake and then quickly veers uphill after .2 of a mile. The trail climbs above Bear Lake and then veers sharply to the left. The lake is 3.6 miles from this point. For the next .5 mile, the trail heads steeply uphill through the pine forest. At this point, another trail junction makes a sharp left (toward the summit of Flattop Mountain). Ignore this junction and continue heading straight. The trail continues to climb. Soon, you will pass a clearing where views of the Mummy Range open up to the north. You will come to a large boulder field and avalanche chute that provides more open views.
The trees begin to thin at this point and views of the mountains to the west appear. The trail through this section is quite easy. The grade is only a gentle uphill slope. As views of the mountains open up, the trail makes a hard right turn. At this point (around mile 3.5), a small social trail to the left is visible. Take this trail and after .2 mile, Lake Helene awaits. It is willow choked around the shore but a few spots are accessible. Follow the indistinct social trail to the left and visit some of the open spots along the lake. Lake Helene is quite shallow so the reflections are amazing here.
After rejoining the main trail, continue heading north on the trail if you want to visit Lake Odessa. Here’s the bad news–the trail descends quite steeply about 600-800 feet to reach the lake. This means you will have to climb this steep and rocky slope on the return unless you through-hike to the Fern Lake trailhead and catch the shuttle back to Bear lake (this adds about 1-1.5 miles to the total hike). Odessa Lake is visible in a couple of spots as you descend. The trail passes the lake before backtracking to the shoreline.
Enjoy lunch at the lake! You will need to recharge your batteries before the steep uphill climb back to Lake Helene. This part of the trail took me about 45 minutes. Once you reach this spot, however, it all downhill from here. The entire hike takes about 5-5.5 hours.
