Lonesome Lake, nestled in the White Mountains of New Hampshire, offers swimmers a pristine alpine experience surrounded by dramatic peaks and evergreen forests. This glacially-formed lake sits at approximately 2,700 feet elevation, creating a remote mountain atmosphere that feels worlds away from civilization. The crystalline waters reflect towering cliff faces and dense woodland, making it one of New Hampshire's most visually stunning swimming destinations. The lake's relatively small size maintains its peaceful character, with minimal development and a focus on natural preservation. The surrounding trails offer spectacular views for hikers and nature enthusiasts. What makes Lonesome Lake special is its combination of accessible swimming with genuine wilderness character-you get alpine beauty without excessive crowds. Practical tips: Arrive early during peak season to secure parking and enjoy the lake's serenity before afternoon crowds arrive. Bring extra layers as mountain temperatures can change rapidly, even in summer months.
About This Lake
Swimming Conditions

The lake reaches depths of approximately 85 feet in its deepest sections, with a gradual drop-off from the shallow northern shore.

Always swim with a buddy, be aware of sudden depth changes, and respect weather conditions that can develop quickly in alpine environments.
