Northern Loop Trail

Overview

If you want the Wonderland Trail’s scenery without its crowds (or mileage), this is your move. The Northern Loop is a strenuous, multi‑day backcountry circuit through Mount Rainier’s wild north side—wide meadows, old‑growth, roaring rivers, and constant glacier views. Expect about 32.6 miles total for the commonly hiked loop (including the Wonderland segment that closes the circuit), with roughly 8,500–10,000 feet of cumulative gain. Most backpack it in 3–4 days; strong parties sometimes squeeze it into two.

Route & Mileage Notes

Mileage varies with your connectors. Starting at Sunrise, you’ll access the loop near Frozen Lake, then drop toward the Carbon River country before rejoining the Wonderland Trail to return. Some references list a longer figure (around 40 miles) depending on approach and connectors; most hiker logs land near low‑30s for the classic Sunrise loop. Plan your itinerary around designated camps along the circuit.

Highlights You’ll Actually Notice

• Grand Park’s broad, flower‑rich meadows and big‑sky views.
• Berkeley Park and Elysian Fields—lush, open country that feels far from the road.
• The Yellowstone Cliffs and colorful volcanic exposures.
• Mystic Lake and constant looks at Rainier’s glaciers—especially the Carbon Glacier, the lowest‑elevation glacier in the Lower 48.
• The airy suspension/log bridge crossings over the Carbon River that make your stomach flutter in the best way.

Difficulty & Trail Character

This is a committing trip: long days, big ups and downs, and remote terrain. Surfaces range from smooth forest duff to rocky alpine tread and glacial moraine. You’ll yo‑yo between ridges and river valleys, so don’t underestimate cumulative elevation. It’s quieter than the Wonderland, which is a pro for solitude—and a reminder to be self‑sufficient.

Camping, Permits, and Regulations

Overnight trips require a wilderness/backcountry permit, and you must use designated camps (examples along the loop include Yellowstone Cliffs, Berkeley Park, Mystic, Granite Creek, Fire Creek, Lake James, Dick Creek, Carbon River, and Ipsut Creek). No pets on park trails. Treat and carry water; streams are common, but some stretches—Grand Park in late season—can be dry.

Best Time to Hike

July through September is the sweet spot: snow has mostly melted, meadows are prime, and river levels are more manageable. Early season can leave steep snowfields on high passes; late September brings cold nights and the chance of early storms. Start early in the day for cooler temps, stable afternoon light, and easier parking at Sunrise.

Getting There & Starting Options

• Sunrise start: Park at the Sunrise Visitor Center and hike to the five‑way junction at Frozen Lake to access the loop. This direction gives you a gentler, net‑downhill start before the bigger climbs.
• Carbon River start: Walk the Carbon River Road about 5 miles to Ipsut Campground, then follow the Wonderland Trail toward the Northern Loop junction. This option front‑loads a stout climb and depends on current bridge conditions.

Tips That Matter

• Check current trail and bridge status before you go—Carbon River log/suspension bridges are prone to washouts and may change year to year.
• Carry extra water capacity for Grand Park in late season.
• If you want even more scenery, consider the Spray Park/Ipsut Pass variant (adds significant mileage) when conditions allow.
• Leave No Trace is critical in fragile alpine meadows—stay on durable tread and skip the social shortcuts.
