Get ready to have more time for outdoor fun at Wolf Creek Park with two exciting updates.

Good news, campers! We’re extending the season. Starting this year, Wolf Creek Park will stay open through Dec. 20, giving you more time to camp, explore, and make memories. Even better, your annual pass gets an extended season, too! The new annual operating schedule is Jan. 4-Dec. 20.

And there’s more! The boat ramp has officially reopened. After plenty of work clearing sediment, this park feature is ready for visitors to enjoy as conditions allow. Check out the incredible transformation in the before and after pictures.

With the extended season, there’s still time to squeeze in more outdoor adventures this year. Pack your gear, plan your visit and come enjoy the extra season at Wolf Creek Park!
