Camping World’s Guide to RVing Mount Rainier National Park

This wild and untamed place is a vast, spectacular playground for outdoor enthusiasts and nature lovers alike. Adventurous travelers will find the national park holds an undeniable allure that is hard to ignore. The mountain is calling, and you must go.

Despite its remote and wild nature, Mount Rainier National Park is actually very accessible by RV. Located just an hour outside Seattle, this wilderness setting is perfect for day trips or extended camping excursions.

Inside the park, visitors will find endless opportunities for adventure, including the chance to explore lush rainforests, hike through alpine meadows, and camp in the shadow of the titular mountain—which happens to be an active volcano.

The park has something to offer anyone who enjoys the outdoors and beautiful space. With more than 150 trails to wander and 147 miles of road to drive, there are many ways to take in this pristine wilderness.

RVers will also find three fantastic campgrounds inside the park boundaries, each with sites for motorhomes and travel trailers. All of this makes it a great destination for camping, exploring, and relaxing.

At the heart of it all is the mountain itself. Those with the time and inclination can make the arduous trek to Rainier’s iconic summit. But be warned, this is no easy undertaking, requiring stamina, determination, and a true spirit of adventure.

When to Visit Mount Rainier National Park

The park is open year-round and offers wildly different experiences depending on when you go. Here’s what you need to know:

Mount Rainier National Park in the Spring

Early spring can be cold and wet, but as the season continues, the park warms up nicely. Average high temperatures range from the low 40s in March to the upper 50s in May. Overnight lows range from the mid-20s to mid-40s during that same time period.

Snow storms can still be quite common at altitude, leading to road closures at times. Be sure to check online or at a ranger station for the current conditions. Crowds tend to be low during this time of year but grow in numbers closer to the start of summer.

Summer is a popular time to visit the park, which is busiest from mid-July through mid-August. That’s when Rainier’s famous wildflowers bloom, bringing a dizzying array of colors with them. The weather is usually fantastic, with dry conditions and warm—but rarely hot—temperatures. Expect daytime highs in the low 70s and overnight lows in the 50s, with cooler conditions at higher altitudes.

Autumn is an amazing time to visit Mountain Rainier National Park, which is awash in the season’s colors starting in late September. Autumn does bring cooler temperatures—expect low 50s during the day and upper 30s at night—and October can be rainy. During peak leaf season, the park’s trails and roads can be quite busy but taper off as fall wanes.

Mount Rainier National Park in the Winter

The national park gets plenty of snow during the winter, with some areas receiving several hundred inches of accumulation. As a result, many of the roads and trails are closed for the season. But the park is still very much open, and there is plenty to do, provided you dress for the weather and don’t mind the challenges that winter brings. Average daytime temperatures tend to hover around 35ºF, while overnight lows drop into the low 20s.

Where to Stay

There are four campgrounds in Mount Rainier, three of which can accommodate RVs. None of the sites have hookups of any kind, so dry camping is the only option. The campgrounds do have water and flush toilets but keep in mind they are only open for a limited time each year, usually running from late May through late September. The park charges a site fee of $20 at each location.

The park’s campgrounds include the following:

Cougar Rock: Located in the southwest region of the park, this campground sits at an elevation of 3,180 feet and features 179 individual campsites. This campground can accommodate motorhomes 35 feet in length and trailers up to 27 feet.

Tips for Your RV Camping Stay

Mt. Freemont Lookout in Mt. Rainier National Park, Washington If you plan on visiting Mount Rainer during the busy summer season, book your campsites early. The park can get very busy in July, August, and early September, making it challenging to find an open site. Reservations for the Cougar Rock and Ohanapecosh campgrounds can be made on recreation.gov, but White River is always first-come, first-served only. Camping or overnight parking is prohibited everywhere other than designated campgrounds. All vehicles must be parked within the designated campsite parking area, not beyond the barriers or on vegetation. Camping is limited to 14 consecutive days in any developed campground within the park and no more than 28 days total in any designated campground within the calendar year. Keep campfires small at all times, and do not leave them unattended. Buy firewood locally to prevent bringing invasive species into the park. Dogs, cats, and other pets must be caged, on a leash (no longer than 6 feet), or otherwise under physical restraint at all times.

How to Get Around

Because it is located in west-central Washington state, access to Mountain Rainier National Park is very good. The park sits a relatively short distance from several major metropolitan areas, including Seattle, Tacoma, Yakima, and Portland.

Visitors to Mount Rainier will find five entrances to the park. The southwest entrance is open year-round and can be accessed via SR 706. The northwest entrance at Carbon River via SR 165 is only open to cars up to the entrance point.

From that point on, only pedestrians and bicycles are allowed. Three entrances on the east are open seasonally from about May to September via SR 123. Once in the park, vehicles can travel SR 706 year-round from the southwest entrance to Longmire Visitor Center, where the road is closed from late September until spring.

However, in the summer season, SR 706 continues through the southern section of the park, becoming Stevens Canyon Road. Once reaching the southwest entrance, vehicles can travel the entire eastern region on SR 123 and SR 410.

All roads are a bit narrow and winding but offer awe-inspiring views and pull-offs to enjoy the scenery or take a break. Traffic jams are possible during the busiest times of the year, especially on the weekends, so be prepared to be patient. The narrow roads can also be challenging for larger motorhomes and travel trailers, so allow plenty of time for your drive. With nearly 150 miles of road to wander, there is plenty to see.

When visiting the park in the winter, always check the current road conditions and closures. Heavy snow closes many of the roads for several months, and others can be shut down based on current conditions.

Cyclists are welcome to bike the roads within Mount Rainier National Park, but they cannot ride on trails. Existing roads are narrow and winding without paved shoulders, so ride carefully. September and October are usually the best times to ride, as car traffic in the park decreases, but the weather remains warm, and the autumn colors are spectacular.

Mountaineering

Mount Rainier is one of the premiere climbing destinations in the world, drawing thousands of alpinists annually. It is a challenging ascent with over 9,000 feet of vertical gain to reach the summit at 14,410 feet.

While not for the faint of heart, the climb is accessible for visitors who are in good physical condition and have experience in mountaineering. Permits are required for such an undertaking, which typically takes two to three days to complete.

Climbing Mount Rainier is not for the inexperienced or unprepared. Anyone wishing to summit the peak should do so with a professional guide, many of which can be hired in the area. For more information, check out the National Park Service guidelines on the park’s website.

Snowshoeing

Additionally, ranger-guided snowshoe tours are offered from December through March on weekends and holidays. Participants are led through park areas to see how plants and animals adapt to winter conditions. The tours are first-come, first-serve,d with a limit of 25 guests per tour.

What to Bring and How to Prepare

Mount Rainier National Park isn’t far from several major metropolitan areas but is a wild and remote place. Here are a few additional tips to help you enjoy your time there:

Be sure to stop in one of the visitor centers to find out which roads are open and how busy the park is, and learn more about the place. This is especially important from late fall into early spring when road closures are common. If you want to climb the mountain, contact a local guide service to ensure you are safe and well-prepared for such an endeavor. Some of the top guiding companies include RMI Expeditions, Alpine Ascents, and International Mountain Guides. Cellphone service is available in some sections of the park but very limited in others. Be prepared to be out of contact with the outside world during portions of your trip. Consider adding a cell booster to your RV if necessary, or alternatively, use two-way radios to communicate with your party. There are two restaurants, two snack parks, a cafe, and a general store located in the park. Those locations are perfect for grabbing lunch or picking up drinks and snacks for the road. You’ll also find plenty of options in the neighboring communities when coming and going. Bring extra layers, even in the summer. The weather can be somewhat unpredictable sometimes, and it is always nice to have a fleece pullover or a rain jacket at your disposal just in case the conditions change. Mount Rainier National Park has a large and diverse wildlife population, some of which can be dangerous to visitors. Be sure to maintain a safe distance from black bears and mountain lions at all times. Do not knowingly approach these animals; if you come across one unexpectedly, slowly but swiftly back away. Winter is an amazing time to visit the national park, but it can be unforgiving for the unprepared. Bring plenty of warm clothes, boots, and other equipment to keep you safe in the Mount Rainier wilderness. Also, let others know where you are going and when you expect to be back.

Brief History of Mount Rainier National Park

While there is evidence that nomadic tribes moved through the Mount Rainier region as far back as 8000 BC, there were no permanent settlements in the area until the 1800s. Instead, those ancient travelers came to the area to hunt, fish, and explore without establishing villages. Archaeologists have found plenty of artifacts left behind by those hunters, including a shelter used on a seasonal basis around 1000 BC.

In 1854, the Nisqually, Puyallup, Muckleshoot, Yakama, and Taidnapam peoples entered into treaties with the US government that allowed them to settle in the shadow of the mountain. Those five Native American tribes already lived in the area but still hadn’t established permanent settlements. They would remain on those lands for several decades that followed.

In 1893, the federal government created the Pacific Forest Reserve to protect the lands on and around the volcanic mountain. Just six years later, President William McKinley would sign a bill that officially created Mount Rainier National Park. The goal was to preserve the land for generations to come and protect the peak from urbanization. This was done as much for the natural wonder of the place but also to keep communities well away from a potential volcanic eruption.

Today, Mount Rainier National Park sees more than 1.5 million visitors annually. Roughly 10,000 of those visitors come to climb to the summit of the tallest peak in the Cascade Range.
