Lake Como Beach Swimming Site

$5 per vehicle day pass or $30 seasonal pass, charged Memorial Day through Labor Day; America the Beautiful (Annual, Access, Military, Senior, Golden Age) interagency passes are accepted. Passes available at an electronic fee station near beach overflow parking or through local valley vendors (Darby Ranger Station, 406-821-3913).

Sandy, gently sloping beach is set up for family wading and sand play, but this is an active irrigation reservoir with no lifeguard on duty and no published depth data; water levels and the sand/water line change through the season (fullest May-July, drawn down by August), so adult supervision at the water's edge is warranted.

No significant hike is required. The swimming area is close to parking and access.

40-spot paved lot directly at the swimming site plus an overflow gravel lot to the east; a first-hand visitor source (riversfork.com) says parking is limited and recommends arriving early on summer weekends.

Both motorized and non-motorized boating are popular on Lake Como (bitterroot.info), with a boat launch (two ramps, trailer parking) typically operating mid-May through mid-August alongside the swim season. A regional recreation guide (explorethebitterroot.com) describes Lake Como as offering "peaceful waters for canoeing or sea kayaking," noting motorized boats are also allowed and suggesting early morning/evening for a quieter paddle. Paddleboarding is mentioned as a nearby activity by a local tourism source (riversfork.com), which describes touring the shoreline by SUP and kayak. No no-wake or electric-only restriction was found in any source.

Late May through August, when reservoir water levels are highest (spring through late July is peak fullness); site is open year-round until closed by snow, but beach conditions decline as the reservoir is drawn down through August.

No dogs or glass permitted on the beach; pets must be leashed elsewhere in the recreation area but are not allowed on the beach or in the designated swim area.
