Boulder Lake (New Zealand)

Boulder Lake is a small, remote alpine lake located in the Nelson Lakes National Park on the South Island of New Zealand. It's known for its clear, cold waters and the surrounding mountainous terrain, characterized by rugged peaks and dense beech forest.

The lake is typically accessed via tramping tracks, requiring a multi-day hike through challenging terrain. Popular routes include those originating from Lake Rotoiti or St Arnaud. Due to its isolated location, Boulder Lake offers a relatively pristine wilderness experience.

Recreational activities at Boulder Lake include fishing (typically for trout), hiking, and photography. Backcountry camping is permitted, but visitors are expected to adhere to Leave No Trace principles to protect the environment.

The lake's name likely derives from the presence of numerous large boulders around its shoreline. The Department of Conservation (DOC) manages the Nelson Lakes National Park and provides information regarding track conditions, weather forecasts, and permit requirements for camping and other activities.

Boulder Lake plays a role in the local ecosystem, providing habitat for various plant and animal species. Its waters contribute to the broader hydrological system of the region. The lake and its surrounding area hold cultural significance for Māori, the indigenous people of New Zealand, who have a long history of connection with the land.
