What to Expect

Starting from the Sunrise parking area, you'll follow a well-maintained path along Sourdough Ridge as it winds through carpets of lupine and paintbrush in late summer. The trail rolls gently upward with a few short switchbacks — nothing brutal, but enough to get your heart rate up. The ridge walk itself is the main event: you're fully exposed above treeline with drop-dead views in every direction. Mount Rainier dominates the southern skyline so completely it almost looks fake, while Baker and Glacier Peak float on the northern horizon like distant sentinels. The final push to Dege Peak's summit rewards you with a full 360-degree panorama that ranks among the best view-to-effort ratios in the entire park. This is the trail you bring visiting friends on when you want to blow their minds without destroying their knees.

Safety Advisory

The entire ridge is exposed with no tree cover — lightning storms roll in fast during summer afternoons. If you hear thunder or see building cumulonimbus clouds, descend immediately.

Snow can linger on sections of the trail well into July. Early-season hikers should check the Sunrise road status with the park before driving up, as the road itself often doesn't open until late June or early July.

Pro Tips

Trail Tip

Arrive at Sunrise before 9 AM on summer weekends — the parking lot fills completely and rangers will turn you away at the gate. Weekdays are dramatically less crowded.

Trail Tip

The Sunrise area sits near 6,400 feet, so even on warm Seattle days expect temperatures 20-30 degrees cooler up top. Layer up and bring a wind shell for the exposed ridgeline.

Trail Tip

For the best photography, hike in the last two hours before sunset when Rainier glows amber and the Cascades stack up in purple silhouette layers. Most day-trippers are gone by then, so you'll practically have the ridge to yourself.
