At Mount Rainier, bicyclists can enjoy bicycling that is both challenging and scenic. Bicycles are allowed on park roads but they are not permitted on any hiking trails and the park does not have any designated bike trails.
September and early October are generally excellent times for bicyclists to visit Mount Rainier. During these months, there are usually fewer vehicles on the roads and fall colors enhance the scenery. However, many facilities and services are reduced or discontinued after Labor Day due to the probability of snowfall.
Be aware that the park may temporarily close any road to bicycle use. Signs will mark closed roads and bicyclists can check current road status when planning a trip. Availability of bicycling equipment in or near the park is very limited and bicyclists should be prepared to make repairs on their own. For your safety, wear a helmet.
Bicycling Safety & Regulations
Park roads are steep, narrow, winding and have unpaved shoulders. There are several significant elevation gains and losses. Bicyclists are advised to maintain safe speeds on downhill sections. While in the park, bicyclists are required to ride single file. Bicyclists may ride two abreast only on Westside Road and Carbon River Trail (former road), where vehicles are not allowed. However, please be aware of hikers also using those routes and yield to hikers.
Most of the park does NOT have cell coverage.
Please review additional bicycling safety guidelines and regulations for Mount Rainier National Park.
