If you’re craving a lush, low-key forest escape that feels worlds away from the city bustle, the Evergreen Trail Loop at Rockport State Park is pure magic—especially in spring.

Getting There from Seattle (via Burlington)

From Seattle, hop on I-5 North and head toward Burlington (about an hour’s drive). Take Exit 230 for SR 20 East (North Cascades Highway) in Burlington. Follow SR 20 East for roughly 37 miles through the fertile Skagit Valley farmlands and past the Mount Vernon area. You’ll pass charming small towns and, on a clear day, catch your breathtaking glimpses of Sauk Mountain rising dramatically to the north. Its snow-dusted peak (often visible well into late July) stands sentinel over the area, a reminder that you’re entering the wilder foothills of the North Cascades. The park entrance is well-signed on the right at 51095 State Route 20 in Rockport. Total drive time: about 1.5–2 hours from Seattle, depending on traffic.

 

A Quick Background on the Geography and Geology

Rockport State Park sits in the lower Skagit River Valley, where the North Cascades meet the coastal lowlands. This 632-acre preserve protects a sliver of ancient forest that escaped the logging boom of the early 20th century. Geologically, the area tells a story of tectonic uplift, volcanic activity from the Cascade Range, and massive Pleistocene glaciation. Glaciers carved the broad U-shaped valley you drive through, leaving behind rich alluvial soils that support the park’s towering conifers. The Skagit River, fed by snowmelt from peaks, flows just south of the park. It’s also traditional territory of the Upper Skagit, Sauk-Suiattle, and Swinomish peoples, who harvested cedar for canoes and cultural uses for millennia.

 

The Trail Experience in Spring

The Evergreen Trail Loop is a 3-mile lollipop-style loop that feels immersive from the first step. In spring, the forest explodes with life: every shade of emerald green carpets the ground in thick mosses and ferns, while trilliums, salmonberry blossoms, bleeding hearts, and yellow wood violets line the path. Skunk cabbage pokes up in wetter spots, adding a splash of chartreuse (and a distinctive scent!).

You’ll meander under 250- to 600-year-old Douglas firs, western red cedars, and western hemlocks—some soaring over 250 feet tall. The trail dips and climbs gently (the only real effort comes near the top of the loop), crossing several lovely streams on charming wooden bridges. One highlight is the bridge over Fern Creek, where you can pause to watch water tumble over small cascades. The sound of flowing water and birdsong fills the air, and the air smells fresh and earthy after rain. Benches are thoughtfully placed for quiet contemplation, and interpretive signs along the connected West Loop share stories of the forest’s life cycle.

In this ancient forest, you’ll also encounter a few fallen trees and branches across or alongside the path—reminders of the dynamic, living nature of old-growth ecosystems where wind, age, and winter storms naturally bring down limbs or whole trees over time. These add to the wild, untamed feel without significantly hindering progress on this well-maintained trail.

It’s usually not crowded, so you’ll likely have long stretches where the only company is the occasional Douglas squirrel or banana slug.

 

Plants and Wildlife in the Area

Rockport State Park’s old-growth forest supports a rich understory and diverse wildlife, especially vibrant in spring. The forest floor bursts with native wildflowers including trilliums, salmonberry, bleeding hearts, yellow wood violets, and red currant. Ferns of all kinds unfurl their fiddleheads, while skunk cabbage thrives in the wetter, swampy sections near streams. Mosses and lichens drape branches and logs in thick emerald layers, and colorful fungi like shelf mushrooms and turkey tail appear on downed wood.

Wildlife viewing is a quiet delight here. Keep an eye (and ear) out for forest birds such as Varied Thrush, Chestnut-backed Chickadee, Winter Wren, Brown Creeper, Golden-crowned Kinglet, Steller’s Jay, and the hammering of woodpeckers. Douglas squirrels chatter from the canopy, and banana slugs glide across the moist trail. Black-tailed deer occasionally browse in the understory, while the nearby Skagit River corridor supports bald eagles (especially in winter) and other raptors. The interconnected ecosystem even benefits from spawning salmon whose nutrients ultimately enrich the towering trees.

Logistics and Practical Tips

• Parking: Ample lot right at the trailhead (Discover Pass required: $10/day or $45/year).
• Restrooms: Clean, accessible facilities are located near the parking area and trail start.
• Best Season: Year-round, but spring is prime for wildflowers, flowing streams, and that vibrant moss glow.
• Dogs and Kids: This is an excellent walk for leashed dogs and families. The gentle grades, bridges, and natural playground elements (logs to balance on, streams to watch) keep little ones and pups happy without being overly strenuous.

Important Note: As of early 2026, parts of the Evergreen and ADA trails are temporarily closed for flood-damage repairs following winter storms. Always check the Washington State Parks website or AllTrails for the latest conditions and updates before heading out.

Whether you’re a seasoned hiker or just need a peaceful reset, the Evergreen Trail Loop at Rockport State Park delivers that deep-forest immersion Washington does best. Pack a picnic, bring your camera for those moss-draped giants (and the occasional fallen giant), and enjoy the simple joy of spring in the North Cascades. Happy hiking! 🌲
