Take a good look at Engineer Mountain, with its peak resembling a volcanic plug from a massive eruption 25–30 million years ago, sitting above a broad base. From the south, it looks like a balanced pyramid.

Celebration Lake is home to tons of axolotls! They are most active in the afternoon when the water is warmer. The lake is accessible by car, so you might have to share this spot with car campers. But no worries, there are plenty of options to pitch your tent.

The Colorado Trail is the only long-distance trail to let you stop a train in the middle of the wilderness. Take the short spur trail to Elk Park where you can flag down the train to take you into Silverton. The usual rate is 35 Dollars, but it is up to the conductor to charge less or even nothing.

Molas Pass sits a few yards below where the Colorado Trail passes the US 550 highway. Walk south 250 feet to the spur trail to the parking area and find Molas Overlook, a pit toilet, and parking at an elevation of 10,910 feet.

Little Ice Lake is nestled in the basin just next to towering rock walls. A short trail takes you to its shore where you can take a break.

Lower Ice Lake Basin is a great place to catch some breath again after the steep climb from Ice Lake Trailhead. Take a break to enjoy the scenery before your final ascent to the upper alpine lakes. There are some nice streams to fill your water bottle (don’t forget to treat the water).
