The best traffic-free bike rides in Mount Rainier National Park

This guide features three dedicated no-traffic gravel bike trails within or near Mount Rainier National Park, offering unique ways to explore the region's rugged beauty away from vehicular traffic.

The gravel bike trails in this guide are generally rated as difficult due to significant elevation gains and distances. You'll encounter unpaved roads, some with rough conditions and large potholes, but also wide, relatively easy gravel sections. For example, the Klepatchee Park via West Side Road route offers a gentle slope on a wide gravel road, while others like the Lonesome lake – Skookum Falls Viewpoint loop involve substantial climbing.

The best time to gravel bike is typically from late summer (mid-July to August) when the subalpine meadows are in peak wildflower bloom and most roads are clear of snow. However, conditions can vary, and some higher elevation routes may remain snow-covered into early summer. Always check current conditions before heading out, especially regarding potential winter closures or bridge access issues.

While the routes in this guide are rated as difficult, the initial sections of some trails, like the West Side Road, can be suitable for families or novice riders. The first few miles of the West Side Road, which is largely closed to cars beyond the initial section, offer a gentle slope and wide gravel, providing a good introduction to gravel biking in a no-traffic environment. Always assess the full route's difficulty and your family's experience level.

You can experience a variety of natural wonders. For instance, the Klepatchee Park via West Side Road route offers wilderness views, follows Fish Creek, and passes through ghost forests. Other trails might lead you past glacial features, subalpine meadows, and old-growth forests. Keep an eye out for highlights like Little Waterfall or scenic viewpoints such as Faraway Rock Overlook, which are accessible within the wider park area.

Within Mount Rainier National Park, pets are generally not allowed on trails, including gravel trails that were formerly roads. They are permitted only on paved roads, in campgrounds, and in parking lots. Always check the specific regulations for the area you plan to visit, as rules can vary. For detailed information, refer to the official National Park Service guidelines.

Mount Rainier National Park requires an entrance fee per vehicle, which covers access for seven days. Parking is available at various trailheads and visitor centers. For specific gravel biking routes, such as those utilizing the West Side Road, you would typically park near the Nisqually Entrance. Always check the NPS website for the most current information on fees, permits, and road closures, as conditions can change.

Yes, all three routes in this guide are rated as difficult, making them suitable for experienced gravel bikers looking for a challenge. The Lonesome lake – Skookum Falls Viewpoint loop from Palisades Trailhead, for example, covers nearly 70 km with over 1500 meters of elevation gain, providing a significant test of endurance and skill. These routes offer substantial climbs and descents through rugged landscapes.

Given the challenging terrain and potential for remote sections, it's crucial to be self-sufficient. Pack plenty of water, high-energy snacks, a repair kit (including spare tubes, pump, and multi-tool), and appropriate layers of clothing for varying weather conditions. Cell service can be limited, so consider carrying a map and compass or a GPS device. Always be prepared for repairs and unexpected changes in weather.

Public transport options directly to the trailheads within Mount Rainier National Park are very limited. Most visitors access the park and its trails by private vehicle. It's advisable to plan for personal transportation to reach the starting points of these gravel biking routes.

Within Mount Rainier National Park, you can find lodging options like the Paradise Inn or camping at locations such as Mowich Lake & Camp. These facilities offer basic amenities. However, amenities directly along the no-traffic gravel trails themselves are scarce, so it's essential to carry all necessary supplies, including food and water.

The routes in this guide vary in length, offering options for different endurance levels. The shortest route, Klepatchee Park via West Side Road, is approximately 39 km (24 miles) long. The longest, Lonesome lake – Skookum Falls Viewpoint loop, extends to about 69 km (43 miles).
