Lake Constantine - 7.9 Miles Round-Trip

Lake Constantine is located 3.95 miles from Tigiwon Road in the Holy Cross Wilderness. It occupies an open basin near treeline ringed by damp meadows, tree-topped knolls and rocky outcrops. The lake is especially popular among backpackers for its accommodating terrain, excellent fishing and proximity to the Tuhare Lakes, Fall Creek Pass and Seven Sisters Lakes:

The trail begins on a moderate grade in a heavy spruce-fir forest. It dips at 1.3 miles (10,840’) across a steep, open slope with great views of Fall Creek and distant peaks in the Gore Range.

Walk through a stream that bisects the trail at 1.52 miles and resume steady travel past interesting rock features to the Notch Mountain Trail split (2.34 miles : 11,225’).

The Fall Creek Trail continues SW on mild-moderate undulations to the base of a talus slide and meadow (3.5 miles : 11,240’). It steepens away into the upper valley, where the landscape opens to rolling alpine meadows on the NE corner of Lake Constantine (3.95 miles : 11,371’).

This large, shapely lake is easy and fun to explore. Social trails circle the area and lead to more private areas and ready-to-use campsites. Damp meadows on the east side are rife with flowers, notably elephants head, queens crown, clover and marsh marigold.

The main trail continues up the north side to the inlet area and Tuhare Lakes Trail split (4.55 miles : 11,510'). This attractive space in the upper valley is crossed by streams and lush meadows, and definitely worth exploring if not aiming for the lakes or Fall Creek Pass.

"I went on a three day trip to Lake Constantine in mid-July with four kids aged 11, 14, 14 and 15. Very nice trip but definitely a busy area. Try to arrive before the weekend to get one of the better spots. We saw a beaver, marmots and lots of wild flowers. There were two snowshoe hares that hung around our campsite. They were bold enough to come in and explore our stuff. They found our flip-flops quite interesting and tried to carry them off to nibble in the bush. A day trip to Turhare Lakes made a nice, if strenuous day trip with fantastic scenery on the way. The mosquitoes were very dense at the lake and made much of the stay difficult. Make sure you bring pretty of DEET. The road to the trail head has been graded in the difficult spots. It now simply has some washboards, a few rocks and potholes. If you navigate carefully and go slowly you should be able to make it with most any car."
