Top Things to Do
Paradise Wildflower Spectacle & Skyline Trail
Immerse yourself in the vibrant tapestry of subalpine wildflowers that explode across the meadows of Paradise each summer. For the quintessential experience, embark on the iconic Skyline Trail loop, especially at dawn or dusk, to witness the alpenglow paint the mountain and avoid the midday crowds. Keep an eye out for marmots and deer grazing peacefully among the blooms.
Sunrise Point's Panoramic Grandeur & Burroughs Mountain
Ascend to Sunrise, the highest point reachable by car in the park, for unparalleled 360-degree views of Mount Rainier, the Cascades, and even Mount Adams and Baker on a clear day. For a truly invigorating experience, hike a portion of the Burroughs Mountain Trail, offering increasingly dramatic, up-close perspectives of Rainier's glaciers and rugged slopes. Arrive early to secure parking and witness the mountain emerge from the morning mist.
Serene Mowich Lake & Tolmie Peak Lookout
Escape the main crowds by venturing to the park's quieter northwest corner, where the pristine, deep-blue waters of Mowich Lake offer a tranquil retreat. From here, embark on the moderately challenging hike to Tolmie Peak Lookout, a historic fire tower that rewards you with one of the most breathtaking, unobstructed views of Mount Rainier reflecting in Eunice Lake below. The gravel road access means fewer visitors, making it a true hidden gem.
Ohanapecosh's Ancient Forest & Hot Springs History
Step back in time amidst the towering, ancient cedars and Douglas firs of the Ohanapecosh area, a lush, old-growth forest on the park's southeast side. Wander the easy Silver Falls Loop, feeling the cool, damp air and listening to the gurgling river. This area also holds the fascinating history of the park's original hot springs resort, offering a glimpse into early tourism and a quieter side of the park.

Essential Travel Tips
Mount Rainier is implementing a timed entry reservation system for peak season (late May to early September) for the Paradise and Sunrise corridors in 2024. Don't get caught off guard! Book your reservation well in advance on Recreation.gov, or plan to enter before 7 AM or after 3 PM to bypass the reservation requirement. This will save you a lot of frustration and ensure you get into the park.
Even if it's sunny and warm at the base, weather at higher elevations like Paradise or Sunrise can change in minutes. Always pack layers – a moisture-wicking base, an insulating mid-layer (fleece or puffy), and a waterproof/windproof outer shell. Don't forget a hat, gloves, and sunscreen, even on cloudy days; the UV index is high.
Food options inside the park are extremely limited and pricey, especially at Paradise Inn or Sunrise Day Lodge. Save a ton of money and time by packing your own picnic lunch, snacks, and plenty of water. There are fantastic spots to enjoy a packed meal with incredible views, like along the Nisqually River or at Reflection Lake.
You're in bear country, so know the basics: carry bear spray (and know how to use it), make noise on trails, and never leave food unattended. Also, while there are plenty of streams, always filter or treat any water you collect from natural sources to avoid giardia or other nasties. Better safe than sorry!
Gas stations are non-existent inside the park and can be sparse and expensive in nearby gateway towns. Fill up your tank completely before you enter, especially if you plan on driving between different park areas. Consider purchasing an America the Beautiful Pass if you plan to visit other national parks within a year; it's often more cost-effective than paying the per-vehicle entrance fee.
Mount Rainier's delicate alpine meadows are easily damaged. Always stay on marked trails, even if it means walking through a puddle. Never feed wildlife – it's harmful to them and can make them aggressive. Pack out everything you pack in, including all trash and food scraps, to preserve the park's pristine beauty for everyone.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Frequently Asked Questions
When is the absolute *best* time to see the wildflowers at Mount Rainier, and how do I avoid the biggest crowds?
The peak wildflower bloom in Paradise and Sunrise is usually late July through mid-August, transforming the meadows into a vibrant tapestry. To beat the crowds, aim for weekdays, especially Tuesday through Thursday, and arrive before 9 AM or after 3 PM. The park's immense popularity means parking lots fill up incredibly fast, so an early start is truly key to snagging a spot and enjoying the trails in relative solitude.
What's the deal with getting around Mount Rainier, especially if I don't want to drive everywhere? Are there shuttles?
While a personal vehicle offers the most flexibility for exploring Mount Rainier's vastness, options are limited if you prefer not to drive constantly. The park does not have an internal shuttle system connecting all major areas like Paradise, Sunrise, and Ohanapecosh. However, during peak summer, a free hiker shuttle operates between Paradise and Reflection Lake/Narada Falls, which can be useful for point-to-point hikes. Otherwise, plan on driving between the main visitor areas, as they are quite spread out.
Everyone talks about Paradise and Sunrise, but are there any less-crowded spots that still offer incredible views or experiences?
Absolutely! For a completely different vibe, head to the Carbon River area on the park's northwest side. It's the only rainforest within the park and offers a unique, lush experience with a flat, easy trail perfect for biking or hiking to the Ipsut Creek campground. Another gem is the Grove of the Patriarchs trail near Ohanapecosh, featuring ancient, massive trees on an island accessed by a suspension bridge – it's magical and often less crowded than the main hubs.
How quickly can the weather change on Mount Rainier, and what should I always pack, even for a 'sunny' day?
Mount Rainier's weather is notoriously fickle and can shift dramatically within hours, even in the height of summer. Always pack layers: a waterproof and windproof jacket, a warm fleece or down layer, and a hat and gloves, regardless of the forecast. Even if it starts sunny, clouds can roll in, temperatures can drop significantly, and rain or even snow can appear unexpectedly at higher elevations, so be prepared for anything.
Are there any specific etiquette rules or 'unwritten laws' I should know when hiking or visiting the park?
Beyond the standard Leave No Trace principles, remember that Mount Rainier is a fragile ecosystem. Always stay on marked trails to protect the delicate alpine meadows and never feed wildlife – it habituates them to humans and can be harmful to their health. Also, yield to uphill hikers, and if you're listening to music, please use headphones; the natural soundscape is part of the park's magic for everyone.
I've heard about timed entry or reservations for some national parks. Is that a thing for Mount Rainier, and what do I need to know?
Yes, Mount Rainier implemented a timed entry reservation system for peak summer 2024 for the Paradise and Sunrise corridors. You'll need a reservation for vehicle entry during specific hours (typically 7 AM - 3 PM) from late May/early June through early September. Check the official NPS website well in advance for the exact dates and to secure your reservation, as they are released in batches and go quickly. Without one, you'll need to enter before or after the reservation window.
