Griffy Lake is a 109-acre body of water surrounded by 1,200 acres of nature preserve just minutes from downtown Bloomington and Indiana University's campus. The lake maintains a quiet, natural character due to motor restrictions - only electric trolling motors are permitted alongside non-motorized craft.

Paddlers access the lake via a boat ramp at the Griffy Lake Boathouse, where canoes, kayaks, and stand-up paddleboards are available for rent at $10 per hour. The facility includes an accessible kayak and canoe launch near the boathouse. Private watercraft require either a daily ($10) or annual ($100) launch permit, available for purchase at the boathouse. Shoreline launching is prohibited.

The boathouse operates seasonally: daily from 8am-8pm May through August, 9am-6pm in September, weekends only in April and October, and closed November through March. The facility provides paddles and life jackets with rentals and includes restrooms. A maximum of 22 watercraft are allowed on the lake at any time.

The lake's natural setting offers opportunities to observe local wildlife while paddling. With an average depth of 10 feet, the water supports populations of largemouth bass, bluegill, redear sunfish, and channel catfish. Eight hiking trails surround the lake, creating an engaging backdrop for paddlers.

Originally constructed in 1924 to address water shortages, Griffy Lake now serves as a backup water supply for Bloomington. The surrounding nature preserve contains rare plant species and mature upland forest, leading to protective regulations. Swimming is strictly prohibited. The lake typically freezes in winter, though ice conditions can be hazardous.

Special paddling programs include guided sunset and night paddles during peak season. For a unique experience, the park offers evening programs through the boathouse during summer months.
