The Ice Caves at Rifle Mountain Park can be seen during the winter months from December to March. Water that runs off the steep limestone cliffs freezes and thaws to form these beautiful turquoise ice formations. The ice caves can be accessed via Koeper’s trail close to the entrance of the Mountain Park, it’s an easy hike into these natural beauties guaranteed to be an experience you won’t forget. Proper ice footwear is highly recommended. Please pack out your trash and pet waste.
