North Dakota Parks and Recreation Department (reservendparks.com) publishes the same three campsite rate bands verbatim on every park's own page (a real, confirmed statewide schedule, not a per-park guess): Primitive campsites $15/night; Modern/Standard campsites $25-30/night; Premium campsites (electricity, water & sewer) $30-35/night - group-site variants at the same band, charged per unit. A non-refundable reservation fee applies per its own /faq page: $5.80 online or in-person, $9.00 by phone. A separate statewide vehicle entrance permit is required for all vehicles entering a state park: $7/day; $35/year (single vehicle); $61.25/year (family, 2 vehicles same household); $28/year (ND-resident senior 65+); free lifetime annual pass (disabled veterans/POWs with 50%+ disability); $28/year (other ND veterans with a service-connected disability). Campsites may be booked 95 days in advance; check-in 4:00 pm, check-out 3:00 pm; stays limited to 14 nights in any 30-day period. Pets are welcome but must stay on a leash. Most parks have off-leash areas or dog parks for your four-legged friends. (This exact sentence is published live on this park's own reservation-FAQ page.)
