About
Ackley Lake State Park is a Montana FWP state park with 26 rustic, first-come-first-served campsites (no electricity, water or dump services).
Fees
Montana FWP's statewide camping rate: $4-$34 per night, depending on season and available amenities. Plus Montana's day-use entrance fee (in addition to the nightly camping rate): Montana residents who pay the $9 state parks fee with vehicle registration owe no daily entrance fee; nonresidents pay $8/vehicle or $4/walk-in per day (or $50/year for a Nonresident Entrance Pass, $35 for a 7-day pass). A 50% camping-fee discount applies statewide to Montana-resident seniors (62+), veterans and people with disabilities.
