About Our Site - Keyhole State Park

 

Keyhole State Park offers swimming, hiking, boating, water skiing, bird-watching and fishing. Some of the state’s largest fish have been caught at Keyhole. You can also reserve one of our 3 group shelters to host weddings, family get togethers and company picnics. Keyhole State Park is located on the western edge of the Black Hills, between Sundance and Moorcroft, and is easily accessed off I-90 at exit 165. Travel north 6 miles and the entrance to Park Headquarters will be on your left. Keyhole State Park has 10 campgrounds, all of which are reservation only.

Wyoming State Parks to Host Public Forum Updating the Public About Proposed Projects at Keyhole State Park

MOORCROFT, Wyo. – April 3, 2026 - The Wyoming Department of State Parks and Cultural Resources will host a public forum to update the public and gather feedback on a proposed visitor center in the Coulter Bay Area at Keyhole State Park.


The proposed Coulter Bay Visitor Center aims to enhance recreation and education opportunities at Keyhole State Park by providing improved visitor services, interpretive exhibits, and a community gathering space for local small groups, and to be a launch point for recreation at Keyhole State Park.  


“We don’t anticipate a new Visitor Center placing strain on existing routes and resources, but we do see it having a very positive impact on existing visitor services in that area of Keyhole State Park,” said Misty Moore, district manager for Wyoming State Parks. “We hear what our users and neighbors are saying there, and want to reach consensus on the best options.”


This forum follows up on a January meeting at the Pine Haven Community Center, where preliminary concepts and planning information were presented. Wyoming State Parks has revised its vision for Coulter Bay in response to public feedback. The event will again invite conversation to guide next steps in the project development process and give park users and residents an opportunity to learn more about how the new facility will support visitor experiences and natural resource education at Keyhole.


The public meeting will be held:


Date: Apr. 14, 2026

Time: 11:30 a.m. and 5:00 p.m.

Location: Pine Haven Community Center, 3 Industrial Park, Pine Haven, WY 82721


“We are looking forward to presenting a revised concept for the Coulter Bay Visitor Center at Keyhole State Park,” said Carly-Ann Carruthers, planning manager for the Wyoming Department of State Parks and Cultural Resources. “We value the input of our visitors and partners, including the Bureau of Reclamation, as we craft plans for enriching experiences at the park.”


Those unable to attend in person can review the presentation materials and submit feedback via an online public comment form at Bit.ly/PublicCommentKSP following the meeting.
