A National Natural Landmark, Mammoth Spring is one of the world’s largest springs with nine million gallons of water flowing hourly. The park also features an 1886 Frisco train depot and museum. Adding to the things to do here are a playground, picnic area, baseball field, walking trail, Arkansas Welcome Center, and gift shop.
First, stop and cross the bridge of the display pond and feed the fish, who know how to beg. Explore our Aquatic Education Center/Aquarium and see several native fish in a new light. Walk through our pollinator garden and witness the incredible service that these animals provide. Take a stroll around our grounds, with unique pond and raceway rearing systems where we raise our aquatic species.
Some people call Grand Gulf State Park the “Little Grand Canyon.” Some just call it “breathtaking.” The park is one of the natural wonders of the Ozarks, presenting the most spectacular collapsed cave system in the Ozarks. The "Grand Gulf" stretches for about three-quarters of a mile between 130-foot-high walls. Visitors can view the gulf from trails on top or from the floor where they can walk under the natural bridge, which spans 250 feet with a 75-foot-high opening.
Spring River is a popular destination for trout and walleye fishing. The river flows from Mammoth Spring to Hardy and offers excellent floating and fly-fishing opportunities. The upper Spring River has a large riffle area that can be accessed from Lasseter Access Area, where you may catch rainbows, browns, cutthroats, or brooks. The three-mile stretch from Mammoth Spring to Dam 3 (an old hydropower structure) is ideal for wading or fishing from the bank, except for the deep section near the dam, which provides good boat fishing. Make sure to get your fishing license before casting your rod!
