Blue Marsh Lake is a 6,100 acre-project having a 1,150-acre lake. Facilities include a day use area with swim beach, bathhouse, food concession, picnic areas, volleyball courts, pavilions available for rental; visitor center; three boat launches; and a stilling basin. Trails include a 30-mile multi-purpose hiking/biking trail and three interpretive trails, one being ADA accessible.
Reservations for Blue Marsh Lake are made through Recreation.gov. In peak season, the most popular campgrounds are typically claimed within minutes of each release — which is why the park reads as "sold out" for most of the year.
Sold out is not final, though. People book far ahead and plans change, so cancellations return to the official calendar throughout the season — with no announcement, at any hour. A cancelled site is bookable by whoever sees it first.
