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.

Reminder: Online Survey for Proposed Projects at Keyhole State Park Closes Feb. 15


MOORCROFT, Wyo. – Feb. 3, 2026 – The Wyoming Department of State Parks and Cultural Resources reminds the public that the online survey related to the proposed projects at Keyhole State Park will close at midnight on Sunday, Feb. 15, 2026.


The survey follows a public forum held in January and provides an opportunity for park users, local residents, and stakeholders to review project information and share feedback if they were unable to attend the meeting in person.

“Public input is an important part of our planning process,” said Carly-Ann Carruthers, planning manager for the Wyoming Department of State Parks and Cultural Resources. “We encourage anyone who has not yet shared their thoughts to take a few minutes to complete the survey before it closes.”

Presentation materials from the public forum and the online survey are available at Bit.ly/WYPublicForum. All comments must be submitted by 11:59 p.m. on Sunday, Feb. 15, 2026.


The proposed Coulter Bay Visitor Center is intended to enhance recreation and educational opportunities at Keyhole State Park by providing improved visitor services, interpretive exhibits, and a community gathering space, while serving as a launch point for park recreation.

“It’s important that this facility reflects the expectations and needs of the people who use and care about Keyhole State Park,” said Misty Moore, district manager for Wyoming State Parks. “We appreciate everyone who has taken the time to provide feedback.”
