McGrath is not connected to Alaska's road system, but local roads are used by ATVs and trucks. Winter trails are marked to Nikolai (50 mi) and Takotna (20 mi). Residents rely on air service and barges to deliver cargo. Air facilities include a state-owned asphalt runway with a crosswind landing strip. The Kuskokwim River is the seaplane base. A boat launch ramp site is available. The river is used for travel when it's frozen during the winter months.
