Snow accumulation varies tremendously across Rocky Mountain National Park. The West Side of the park receives moisture-bearing storms first, and has the deepest accumulation of the fluffy white stuff. Often there is sufficient snow cover by late November to cover rocks, logs, and other obstacles, making trails and slopes safe for skiing and snow shoeing. There are no ski lifts in the park, so skiers generally use cross-country equipment that allows them to ascend as well as descend in mountainous terrain.

The East Side of the park, the lee side of the mountains, is relatively dry and snow cover is patchy, especially early in the winter. Strong winds blow what snow falls into drifts, covering some areas but exposing others. Snow coverage is often intermittent below 9500 feet. Above that elevation, steep slopes and variable snow coverage result in challenging ski conditions.

Although the East Side does not really offer beginning cross-country skiing, it does have a selection of trails suitable for the beginning snow-shoer. Free ranger-led walks (link to ranger-led activities) can help you get started. If you don't have your own "shoes", several local stores offer equipment rentals.
