Arrowhead State Park, State park on Lake Eufaula in Oklahoma, US

Arrowhead State Park, now the Arrowhead Area at Lake Eufaula State Park, covers 2,200 acres on a peninsula of Lake Eufaula in Pittsburg County, Oklahoma. It holds 100 tent sites, 91 RV sites, a marina with a restaurant, picnic shelters, playgrounds, a miniature golf course, and a swimming area. The 18-hole, par-72 golf course has bent grass greens, Bermuda grass tees and fairways, sand bunkers, and few water hazards.

The site was transformed when Lake Eufaula was created in 1964 through the construction of Eufaula Dam, turning the region into a recreational destination for southeastern Oklahoma. This development enabled the area to become a public park for outdoor activities.

The park's name comes from the arrowhead-shaped peninsula formed by a bend of Lake Eufaula. The former Arrowhead Lodge, opened in 1965, stands within the grounds; after state operation ended it passed to the federal government in 1983 and to the Choctaw Nation in 1985, which ran a gaming hotel there. Since 2000 the building has housed the privately run Narconon Arrowhead drug treatment centre, a sale that drew local controversy over security and the operators' Church of Scientology ties.

The park provides RV sites, tent camping areas, boat launch facilities, and a pro shop for golf players seeking supplies and advice. Visitors should check seasonal conditions before arriving, as weather and water levels can affect activities like fishing and boating.

Arrowhead Lodge, opened in 1965 as one of two state lodges on Lake Eufaula, was sold to the federal government in 1983 after financial losses, then to the Choctaw Nation in 1985. Since 2000 the building has housed Narconon Arrowhead, a private drug treatment centre run by ABLE, which drew local controversy over its Church of Scientology ties.
