Welcome to Wyoming State Parks, Historic Sites, & Trails

Finding your perfect vacation spot has never been easier!

Mountain bikes, boats and fishing poles are really just toys for grown-ups; so go be a kid again. After all, we've got plenty of trails for getting mud on those tires, including those in Guernsey, Buffalo Bill and Curt Gowdy State Parks.

If making a splash is more your style, we've got space for water sports and fishing at our many reservoirs . Once you're done playing, soak those bones in the therapeutic mineral water at Hot Springs State Park.

"I have the distinction of being one of a handful of people who has been to every Wyoming State Park and Historic site. Maybe the only one who has done it during one month! These are among the best kept secrets in the United States." -- Alan O'Hashi (Facebook Review)

Wyoming Department of Health Issues New Harmful Cyanobacterial Bloom (HCB) Recreational Use Advisories



Wyoming Department of Health Issues New Harmful Cyanobacterial Bloom (HCB) Recreational Use Advisories

The Wyoming Department of Health (WDH) has issued a harmful cyanobacterial bloom (HCB) recreational use Bloom Advisory for Brooks Lake, Flaming Gorge Reservoir, Glendo Reservoir, Rainbow Lake, Sloan Lake, Upper Brooks Lake, and Upper Jade Lake based on data provided by the Wyoming Department of Environmental Quality (DEQ). The WDH is working directly with resource management agencies to ensure that signs are posted at all waterbodies with advisories. Additional details regarding advisory status, including changes to the type of advisory, and other HCB resources can be found at WyoHCBs.org

The WDH issues recreational use advisories when cyanobacterial cell densities or cyanotoxin concentrations pose a risk to people engaging in swimming or similar water contact activities in areas where cyanobacterial blooms occur. HCBs may also pose a health risk to animals. Bloom Advisories are issued when a HCB is present and toxins may be present. Toxin Advisories are issued when cyanotoxins exceed recreational thresholds. Waterbodies under an advisory are not closed since HCBs may only be present in certain areas and conditions can change frequently. Advisories will remain in place until blooms have fully dissipated and cyanotoxin concentrations are below recreational use thresholds identified in Wyoming's HCB Action Plan.

If you encounter a potential HCB, the Wyoming Department of Health and the Wyoming Livestock Board recommend the following:

  • Avoid contact with water in the vicinity of the bloom, especially in areas where cyanobacteria are dense and form scums.
  • Do not ingest water from the bloom. Boiling, filtration and/or other treatments will not remove toxins.
  • Rinse fish with clean water and eat only the fillet portion.
  • Avoid water spray from the bloom.
  • Do not allow pets or livestock to drink water near the bloom, eat bloom material, or lick fur after contact.
  • If people, pets, or livestock come into contact with a bloom, rinse off with clean water as soon as possible and contact a doctor or veterinarian.

Buffalo Bill State Park celebrates Great Dam Day August 20


Come celebrate the 28th Anniversary of the Buffalo Bill Dam Visitor Center during Great Dam Day, August 20, from 8 a.m. to 5 p.m.

Buffalo Bill Dam Visitor Center along with Buffalo Bill State Park host this year’s event at the Visitor Center located six miles west of Cody on HWY 14/16/20.

In addition to the events planned, there will be different interpretive learning stations located below the visitor center on the old road to Yellowstone below the dam.

Through cooperation with the Bureau of Reclamation, the old dam road is open next to the visitor center one time during the year, allowing the public to walk or ride bicycle to take in the views from 9 a.m. until 3 p.m. Rides back to the center will be available. 

Fat Racks BBQ will have food available for purchase at the visitor center lot. Also, the Bureau of Land Management will have activities for kids to participate in.

Buffalo Bill Dam was completed in 1910 and is on the National Register of Historic Places. Buffalo Bill Dam was the tallest dam in the world upon completion. Construction began in 1904 and work was dangerous, difficult and tedious.

The completed water storage supplies four irrigation districts encompassing over 93,000 acres of farmland.

Youth and adults alike will find the views and history fascinating. Staff and volunteers will be on-site to answer questions and provide assistance.

The event is open and free to the public. For any questions, please contact the Buffalo Bill Dam Visitor Center General Manager Leslie Slater Wilson, at (307) 527-6076.
