Summit Lake Park

Summit Lake Park is a protected alpine area in the Rocky Mountains at nearly 4000 meters with arctic plant species and rocky landscapes. The roughly 160-acre expanse consists mainly of alpine tundra with rare geological formations.

The area became protected in 1924 as part of the Denver Mountain Parks system and gained National Natural Landmark status in 1965. This recognition secured long-term preservation of this high alpine region.

The park maintains a collection of arctic plants found only in this location and the Arctic Circle, representing a vital preservation of natural heritage.

The Mount Blue Sky Road access route is partly unpaved at higher elevations and can be challenging in poor weather. Visitors should bring warm clothing and expect sudden weather shifts, as the altitude changes conditions rapidly.

The area hosts permafrost on its eastern side, counting among the rare locations in continental North America with this geological feature. This frozen soil layer remains frozen year-round and shapes the ecosystem in subtle ways.
