Twin Lakes, as its name suggests, is a park comprised of a set of connected lakes to the southeast of Mammoth Mountain. Eruptions of Mammoth Mountain caused the formation of lava cliffs on one side of the lakes. The other side has a campground and ski lodge.

These bizarre rock formations are formed in and around Mono Lake from the salty, alkaline water of Mono Lake in connection with underground springs.

Lake Mary is the crown jewel of the Mammoth Lakes region, and a busy year-round destination. In the summer, you can ride here via the aptly named Lake Mary Road, or via the paved Lake Basin Bikepath. The road and path are not maintained during winter, but the lake is still accessible via snowshoe and cross-country ski trails

Convict Lake is a glacial lake and is surrounded by majestic mountains. The picturesque lake, however, has a very sad history. It gets its name from an incident that happened in 1871, when 29 convicts escaped from Carson City Jail and found a place to hide near the lake. After killing a mail carrier who had found them by chance at Convict Lake, they were followed by military officers and there was a bloody shoot-out. The surviving prisoners were found soon after and lynched.

Horseshoe Lake sits at the end of Lake Mary Road and the Lakes Basin Bike Path. You can stop here for a swim or leave your bike and hike around the lake. One thing of note is that this area has an unusually high concentration of CO2 due to underground gas reservoirs, the U.S.G.S. has been monitoring the CO2 levels since the late 1980s.
