Wonderland Trail

The Wonderland Trail is a 150 km loop trail in Mount Rainier National Park, Washington, in the United States, gaining roughly 6,700 m of elevation over 10 to 14 days. Rated strenuous, it fully circles the 4,392 m volcano, threading through wildflower meadows, old-growth forest and 25 named glaciers for one of North America's finest backcountry circuits.

About the Wonderland Trail

The Wonderland Trail is a 150 km (93-mile) circumnavigation of Mount Rainier, the glaciated stratovolcano that dominates the skyline of western Washington. Unlike a point-to-point route, it begins and ends at the same place, making a complete loop around the mountain and returning every hiker to their starting trailhead. Most parties walk it in 10 to 14 days, though strong ultralight hikers and trail runners occasionally complete it faster.

The trail was built in 1915, originally as a patrol route for park rangers circling the peak. In 1981 it was designated a National Recreation Trail in recognition of its scenic and historic value. Three surviving backcountry shelters — Summerland, Indian Bar and North Mowich — were constructed by the Civilian Conservation Corps between 1934 and 1940 and still stand today.

What makes the Wonderland exceptional is its relentless vertical profile. Rather than contouring the mountain at a constant height, the route repeatedly drops into deep river valleys and climbs back to high alpine passes, accumulating about 6,700 m of total elevation gain over the loop. The highest point is Panhandle Gap at 2,060 m, while the lowest is Ipsut Creek at 710 m — a swing of more than 1,300 m that you will repeat, in various forms, again and again. Roughly 200 to 250 people complete the entire circuit each year, while thousands more sample its finest day sections.

The trail circles a living, glaciated volcano, and the landscape changes character with every valley you cross. In a single day you might descend through silent old-growth forest of Douglas fir and western hemlock, ford a milky glacial river on a primitive log bridge, then climb into open subalpine parkland where marmots whistle and the full bulk of the mountain fills the horizon. The route passes 25 named glaciers, and two suspension bridges carry walkers over the most powerful meltwater torrents. Wildlife is abundant: black bears feed in the berry meadows by late summer, mountain goats work the high crags, and elk graze the lower valleys. This constant variety, packed into a closed 150 km loop, is exactly why the Wonderland is so prized among long-distance hikers.

Route Overview & Stages

The loop is commonly broken into multi-day segments anchored on the 18 designated wilderness camps, which sit 5 to 11 km apart. The table below shows a representative clockwise itinerary starting from Longmire; distances are approximate and stages can be combined or split to match your permitted camps.

Highlights & Points of Interest

• Panhandle Gap (2,060 m) — the highest point on the trail, a stark alpine saddle that holds snow late into summer and offers sweeping views east toward the Cascade volcanoes.
• Indian Henrys Hunting Ground — a famed wildflower meadow with the historic patrol cabin framed against Mount Rainier, widely considered one of the most photographed spots on the loop.
• Spray Park — a high meadow above Mowich Lake carpeted with lupine and paintbrush in season, often regarded as the single most beautiful section of the trail.
• Carbon Glacier — the lowest-elevation glacier in the contiguous United States, crossed via a swaying suspension bridge over the Carbon River.
• Summerland & Indian Bar — twin alpine basins linked by Panhandle Gap, home to two of the surviving CCC shelters and superb sunrise light on the mountain.
• Reflection Lakes — tranquil tarns near Paradise that mirror Rainier on calm mornings, a fitting finale on a clockwise loop.
• Mystic Lake — a serene subalpine lake beneath Old Desolate, with the Willis Wall of Rainier looming above the camp.
• Tahoma Creek suspension bridge — one of two long suspension spans on the route, crossing a glacial torrent below the Tahoma Glacier.

Best Time to Hike the Wonderland Trail

The hiking window is short and weather-dependent. Snow typically lingers on the high passes — especially Panhandle Gap and Spray Park — through early July, and fresh snow can return by late September or early October. That leaves a realistic window from mid-July to late September.

The single best month is August. By then most snow has melted from the passes, river fords are at workable levels, and the subalpine meadows reach peak wildflower bloom. Daytime temperatures at mid-elevation sit comfortably around 18–24°C, while nights at the higher camps can still drop near freezing. Late summer is also typically the driest stretch in the Pacific Northwest, giving the best odds of clear views of the mountain.

As of 2026, hikers should still plan for the region's notorious variability: even in August, multi-day periods of rain and low cloud are common, and snowfields can persist on north-facing slopes after heavy winters. Early July offers solitude and stronger waterfalls but demands snow-travel skills and route-finding on covered tread. By late September the meadows turn gold and crowds thin dramatically, though the first autumn storms become a genuine risk. Always check current conditions with the park before committing to a high-camp itinerary.

River fords deserve special attention when choosing your dates. Glacial streams run highest in the afternoon as the day's melt peaks, so hikers crossing on log bridges and braided channels are wise to tackle the biggest crossings in the cool of the morning. A hot spell or a summer storm can wash out a primitive bridge with little warning, occasionally forcing detours, which is another reason late summer's more stable, drier weather makes August the safest as well as the most scenic window.

Practical Information

Accommodation

There are no huts or lodges on the trail itself — the Wonderland is a camping-only route. Eighteen designated wilderness camps are spaced 5 to 11 km apart, each with 1 to 8 individual sites plus group sites for larger parties; most have a pit toilet and a nearby water source. You must camp only at your permitted site. The three historic CCC shelters at Summerland, Indian Bar and North Mowich offer basic walled refuge but cannot be reserved. Budget around €5–6 per person per night in wilderness camping fees, plus the permit reservation cost below. Before and after the hike, Longmire and the Paradise Inn area offer in-park lodging from roughly €130–230 per night, and the gateway town of Ashford has motels and cabins from around €90.

Getting There & Back

The nearest major airport is Seattle–Tacoma International (SEA), about 100 km and a 2 to 2.5-hour drive northwest of the Nisqually entrance at Longmire. There is no public transport into the park itself, so most hikers drive or arrange a private shuttle from Seattle or Ashford. Because the route is a loop, you finish where you started, which removes the logistics of a car shuttle — a significant advantage over point-to-point treks. If you instead start at Sunrise (the highest road-accessible point at 1,950 m), note that the Sunrise road usually opens only in early July and closes by October.

Permits & Fees

A wilderness camping permit is mandatory for every overnight on the trail. Demand far exceeds supply, so permits are allocated through an annual lottery on Recreation.gov, typically opening in spring, with about 30% of itineraries held back for walk-up requests at park ranger stations. Expect a reservation processing fee of roughly €20–24 per itinerary. Every vehicle also needs a park entrance pass, around €28 for a 7-day permit. Apply early, build flexibility into your camp choices, and have backup itineraries ready. Full, current rules are published by the park authority: Mount Rainier National Park — Wonderland Trail, with bookings handled via Recreation.gov wilderness permits.

Gear & Packing List

The Wonderland's combination of cold high camps, glacial river crossings and frequent rain makes gear choices matter. You will carry food for multiple days between resupply caches (which can be pre-placed at Longmire, Mowich Lake and the White River ranger station), so a capable pack is essential. For a 10–14 day carry, a roomy ultralight pack such as the Arc Haul Ultra 60L or the durable 3400 Windrider handles full loads well, while lighter hikers running shorter food carries between caches may prefer the trimmer 2400 Windrider. Whatever you choose, prioritise a reliable rain shell, a warm layer for sub-zero nights, and waterproof storage for your sleep system. For guidance on choosing a pack, our roundup of the best ultralight backpacks of 2026 tests seven leading options side by side.

Food planning is critical on a trail this long: with 6,700 m of climbing you will burn far more than on flat terrain. Read how many calories you need hiking a full day before you pack your caches, and aim for energy-dense, lightweight meals to keep pack weight manageable across the loop.

Similar Trails You Might Like

If the Wonderland's mix of alpine passes, river valleys and big daily climbs appeals, you will likely enjoy other classic mountain circuits and connector routes. The dramatic cross-border crossing of the Albanian Alps is a perfect shorter taster of high-mountain hut-to-village hiking — see our guide on how to hike the Theth to Valbona Trail in Albania for a route with similar alpine scale but a far gentler logistical footprint. Like the Wonderland, it rewards early planning, a head for sustained climbing, and a willingness to walk in changeable mountain weather — skills that transfer directly between the world's great circular and connecting treks.

Frequently Asked Questions

When is the best time to hike the Wonderland Trail?
August is the single best month. Snow has usually cleared from the high passes by then, river fords are manageable, and the subalpine meadows reach peak wildflower bloom. Late summer is also the driest period in the Pacific Northwest, giving the best chance of clear views. Snow can linger into early July and return by late September.

How difficult is the Wonderland Trail?
It is rated strenuous. Although the highest point is only 2,060 m at Panhandle Gap, the route relentlessly drops into deep valleys and climbs back to alpine passes, accumulating about 6,700 m of total elevation gain over 150 km. Glacial river fords, multi-day food carries and changeable mountain weather all add to the challenge.

How many kilometres per day will I hike?
Most parties walk the 150 km loop in 10 to 14 days, averaging roughly 11 to 18 km per day. Daily distances are dictated by the fixed wilderness camps, which sit 5 to 11 km apart, and by the heavy elevation gain — a 16 km day with 1,500 m of climbing feels far longer than the distance suggests.

Where do you sleep on the Wonderland Trail?
The trail is camping-only, with no huts or lodges. There are 18 designated wilderness camps spaced 5 to 11 km apart, each with assigned sites, a pit toilet and a water source nearby. Three historic CCC shelters offer basic refuge but cannot be reserved. You must camp only at the site listed on your permit.

Do I need a permit for the Wonderland Trail?
Yes. A wilderness camping permit is mandatory for every overnight. Because demand is high, permits are allocated through an annual lottery on Recreation.gov, with about 30% of itineraries reserved for walk-up requests. Expect a reservation fee of roughly €20–24 plus a park entrance pass of about €28 per vehicle. Apply early and prepare backup itineraries.
