Lake Como Beach Swimming Site

A unique opportunity in Montana! This swimming area is located on beautiful Lake Como, located between Darby and Hamilton, Montana. It features a sandy beach area, picnic tables, accessible restrooms, dressing facilities, paved parking, water, and garbage service. The beach is popular during the summer months when the lake is full, usually until August.

No Dogs/Glass on Beach. 

Lake Como is an irrigation reservoir.  Water levels fluctuate throughout the year, with the lake typically being at its highest from spring through late-July. Lake Como plays a vital role in irrigation for the Bitterroot Valley. The lake serves as a late-season water source, storing water from Rock Creek and releasing it to the main canal that serves a 72-mile stretch of irrigation to the Valley.

Boating - Non-Motorized Info

Non-motorized boats can be used from the swimming area.  

Motorized boats can access the boat launch area on the south side of the lake. A floating dock is installed from typically late May and is removed by mid-August depending on water levels.  

Lake Como is an irrigation reservoir, so water levels are highest in the spring and early summer, making it ideal for boating during that period.
