WTA is a nonprofit that needs you

We’re just as excited as you to get the summer hiking season started. We're psyched our website and work for trails help you get outside.

But we're a nonprofit run on donations from regular people. If everyone who visited this website this holiday weekend donated $9/month, it would fully fund our work for the next 2 years. Of course, time spent outdoors is priceless, but every donation large or small helps us support those experiences for everyone.

Please take 2 minutes to chip in $9.

Thank you and happy hiking!

Begin this loop hike at Mountain Lake. Begin near the group camp and head up the trail toward Little Summit and Summit Lake. The trail doesn't waste much time, and you'll soon begin climbing. At the trail junction at just after a mile, you can continue forward or, if you'd like to add a short side trip, head up to Little Summit before coming back and resuming your trip. 

Continue up and soon begin to get some views. At the junction with a trail that comes from Cold Springs, continue straight. Pass by the outlet of Summit Lake and then continue along the ridge before reaching the top of Mount Constitution. You can also drive to this location, so you'll probably have company. Take your time taking in all the views and be sure to climb up the tower. When you're ready, continue your trip from the parking lot by finding the trail to Twin Lakes. 

Descend quickly. When you reach a junction on your left, you can take a detour to Twin Lakes or continue on the main trail. When you reach the north end of Mountain Lake, keep to your right and follow the trail back to where you started.
