Keyhole Reservoir in northeastern Wyoming offers diverse paddling opportunities across its 9,300 acres and 53 miles of shoreline. The lake is located in Keyhole State Park, about 17 miles northeast of Moorcroft and easily accessed off I-90 at exit 165.

Paddlers can launch from five boat ramps around the lake, four of which have attached docks. The Keyhole Marina provides rentals for kayaks, canoes, and paddleboards during its seasonal operation from May 1 to September 30. Swimming is permitted anywhere on the lake except near boat ramps and the marina, with a designated beach area south of the marina.

The reservoir supports a variety of fish species including walleye, bass, northern pike, crappie, and catfish. Fishing is allowed year-round with a valid license, though it's prohibited from boat docks. Ice fishing is popular in winter when the lake freezes over.

Wildlife viewing opportunities abound, with over 225 bird species in the area. Paddlers may spot white pelicans, ospreys, and bald eagles depending on the season. Mule deer, white-tailed deer, and antelope are commonly seen along the shoreline.

Ten campgrounds with 286 sites surround the lake, providing convenient overnight options for multi-day paddling trips. Amenities include picnic areas, a trailer dump station, and hiking trails. The Keyhole Marina offers additional services like a snack bar, general store, and campsites with hookups.

While specific paddling routes aren't outlined, the lake's numerous inlets and coves provide ample exploration opportunities. The eastern inlet offers a more secluded paddling experience and shelter on windy days. Paddlers should be aware that the water can be quite shallow in some areas.
