Highland Mary Lakes are subalpine and tend to remain frozen through early summer. The lakes are in a valley largely devoid of trees, so you will have a clear view of the lakes and wildflowers. This is a popular hiking area and connects to both the Colorado Trail and Continental Divide Trail. You can fish in the lakes but camping is not permitted.

The trail is a nontechnical singletrack which climbs steadily all the way up to the CDT. The trail is beautiful and very remote — it is not uncommon to see bear, elk and moose. Definitely bring bear spray in your belt or pack and running with bells is not a bad idea. Just as you start to break out of treeline at the top you will be presented with a fork; both directions lead to similar spots on the CDT, but the right fork takes you to Williams Lake and the left trail takes you to a couple smaller lakes.

Spotted Lake is a little smaller than Archuleta Lake a little further north. It is a great water source and has plenty of fish. Camping options are better at Archuleta Lake though.

At a little over 11,600 feet, Crater Lake sits right on the edge of treeline. The Twilight Group (a trio of 13ers) makes the backdrop with the Needle Mountains in a line to the east. The trail traveling to the lake is popular, but not as many people who start towards the lake end up getting there because of the hilly trail. The good news is that it's all downhill on the way back.
