Caving

Visiting Bighorn Cavern
Permits for the cave must be obtained from the National Park Service at the Bighorn Canyon Visitor Center in Lovell, Wyoming. Caving parties must have 3 to 6 people and contain at least one person familiar with the cave. Only two parties are allowed in the cave at any one time. The entrance is protected by a cage which also protects the cavers' ropes that are necessary to negotiate the 70-80 foot cave entrance. So far fourteen miles of passageway are known making it the longest cave in Montana.

Bighorn Cavern contains a decent variety of stalactites, stalagmites, columns, soda straws and bacon, but the really outstanding feature is the variety of crystal formations. White gypsum flowers, aragonite needles, epsomite crystals in fragile curls, and calcite crystals decorate the cave.

Fishing

Bighorn River
The Bighorn River is a tributary of the Yellowstone and flows approximately 461 miles from south to north through Big Horn County, with the Greybull and Shoshone Rivers flowing into it from the west. The upper reaches of the Bighorn, south of the Owl Creek Mountains in Wyoming, are known as the Wind River. The two rivers are sometimes referred to as the Wind/Bighorn. The Wind River officially becomes the Bighorn River at the Wedding of the Waters, on the north side of the Wind River Canyon near the town of Thermopolis. From there, it flows through the Bighorn Basin in North Central Wyoming, passing through Thermopolis and Hot Springs State Park. At the border with Montana, the river turns northeast, and flows past the north end of the Bighorns, through the Crow Indian Reservation, where the Yellowtail Dam forms the reservoir Bighorn Lake. The reservoir and the surrounding gorge are part of the Bighorn Canyon National Recreation Area. It is joined by the Little Bighorn River near the town of Hardin, Montana. Approximately fifty miles further downriver, it joins the Yellowstone.  The river was named in 1805 by fur trader François Larocque for the Bighorn Sheep he saw along its banks as he explored the Yellowstone River.

Greybull River
The Greybull River is a tributary of the Big Horn River and is approximately 90 miles long. Native American tribes named the Greybull River after an albino bison bull that once roamed the area. On a cliff overhanging the river near the town of Greybull Wyoming in a pictograph is pictured a buffalo with an arrow through his body. With this picture goes the story that an old gray bull which ranged up and down the river chased by the Indians was finally killed by driving it over the edge of this bluff into the river below.
 
The Greybull River south of Cody Wyoming runs through some of the most remote backcountry in the Greater Yellowstone Ecosystem. The river rises near Francs Peak in the Absaroka Mountains in the southwest corner of the Big Horn Basin. The Wood River, which drains a part of the Absaroka Mountains to the south, joins it west of Meeteetse, continuing through the southern parts of Park County and Big Horn County before flowing into the Big Horn River near Greybull. Along its 90-mile corridor, water travels from snow-capped peaks in the Absaroka Mountains to sagebrush flats and prairie at its confluence with the Bighorn River.
 
The Greybull River watershed is famed for supporting the best genetically pure populations left of Yellowstone cutthroat trout remaining in the west, a species decimated elsewhere in the West by non-native species and altered water flows. Much of the upper river is considered a blue ribbon trout stream, The River's high-quality aquatic habitat is spurring efforts among many landowners to join with partners to protect and restore this biologically important watershed. If you are chasing Yellowstone Cutthroats. This river's lower half is almost completely private. When you enter National Forest you have over 20 miles of incredible hike-in-fishing, with fish ranging from 10-27 inches this is a crown jewel for Cutthroat in America. Dry fly fishing for Yellowstone Cutthroats is excellent on the Greybull. If you are interested in small stream fishing in a beautiful location this is the place.  Much of the Greybull River after it leaves the Absaroka Mountains is private ranch land but access is possible through permission and guided fishing trips.
 
Whitewater kayaking, rafting, and paddling:  CLASS I-III
 
Venus Creek to Forest Service boundary section
This section of Greybull River in Wyoming is 6 miles long and has been rated as a class I-III section by American Whitewater. Whitewater rafting and kayaking spots in Wyoming are harder than the national norm, so don't forget that quite a few of the sections here are not easy. There are no other sections to paddle along Greybull River other than the Venus Creek to Forest Service boundary section. The wild scenery of the Absaroka Range is great. No matter if you're whitewater rafting or kayaking this is an area with not too many other places for that.
To reach the upper end of the Greybull River, continue west on State Highway 290. The road turns to dirt and into Forest Road 208 at the same place. Continue on this road until you reach the Jack Creek Trailhead. The access to the upper reaches of the Greybull River is by foot or horseback.
