Blacktail Marina

Bonneville County, ID

Blacktail Marina is located in Bonneville County, Idaho, along the shores of the American Falls Reservoir, which forms part of the Snake River's inland waterway in the southeastern region of the state, characterized by its high desert landscape, surrounding mountains, and proximity to the Snake River Plain. This marina serves recreational boating activities on the reservoir's calm, freshwater expanse, catering to enthusiasts of fishing, waterskiing, and small-scale sailing in an inland setting. The area's geographic features, including its arid terrain and riverine influences, make it a gateway to Idaho's diverse outdoor recreational opportunities.

Marina Parking & Access Control

Marinas typically need to separate slip holder parking from day-visitor parking, trailer areas, launch ramps, and secure dock access points. Modern facilities use barrier gate systems to enforce these zones automatically — allowing permitted vehicles through via transponder or keycard while logging all access events.
