Great Hikes On Orcas Island

Orcas Island, also called the "Emerald Isle,"  is full of shady paths, water view summits, and meandering beach walks. Explore these favorites!

We'd like to acknowledge the Coast Salish peoples as the first stewards of these islands whose traditional lands and waters include the San Juan Islands and surrounding Salish Sea.

Cascade Lake, Moran State Park

Cascade Lake is the center of outdoor fun in Moran State Park. Boat rentals, a swimming area, picnic shelters and three campgrounds to choose from give you plenty of relaxation time after hiking, birdwatching or horseback riding. A great place for kids, Cascade Lake has a 3-mile trail around the lake, a wooden bridge and a quiet lagoon for paddling and swimming. Purchase day passes at the park entrance and enter a world of natural beauty.

Accessibility

Though there is minimal elevation gain overall, the trail is fairly challenging with some steep sections, narrow footholds, and many areas of large rocks and roots in the trail. There are also a couple of turnstile gates that are difficult to navigate with mobility aids. The most accessible portion is at the main day use area, where there are picnic tables beneath mature western red cedar. The firm, natural surface trail leads to a metal bridge over Moran Creek. You could continue for approximately 0.10 mile before there is an incline where you have to step up on roots, followed by a large root mat with roots rising up to six inches, and then a narrow turnstile. 

  • Parking: Paved parking at small lots on either side of Olga Rd, just east of the park office. 
  • Amenities: Accessible restrooms and picnic tables.

Mount Constitution

If you want the challenge of a steep hike and the reward of breathtaking views, grab your hiking boots and a packed lunch and head to Mount Constitution in Moran State Park, the highest point in the San Juan Islands—2,409 feet. It’s not a hike to be rushed, however, as there is a lot to appreciate on the way up. Hike from the cool shade of old-growth forest to sunshine and wildflowers in alpine meadows.

From the summit, you’ll have 360-degree views of the San Juan Islands, Vancouver, and the mainland, bracketed by snow-tipped Mt. Baker and Mt. Rainier. Enjoy an added touch of historical interest in the watchtower, built from hand-cut stone by the Civilian Conservation Corps in 1936.

If you have small children or just fancy something less strenuous, there are a multitude of easier hikes farther down the mountain. Or arrange to be dropped off at the top and have someone pick you up at the bottom for a leisurely downhill hike.

There is a paved road all the way up Mount Constitution, so consider parking partway up for a leisurely and beautiful three-mile stroll around Mountain Lake—you can even jump in for a cooling swim. Beyond Mountain Lake, trails lead out to Cascade Falls and Twin Lakes. With over 38 miles of trails, 5,200-acre Moran State Park offers something for every fitness level.

Accessibility

Mount Constitution, the highest point in the San Juan Islands, offers panoramic views of the islands and the Salish Sea. On a clear day, you can see Mount Baker and the North Cascade Mountains. There are limited views from the parking area. For the best views, you must take a short but very steep gravel path up to the viewpoint, and then cross over an exposed rocky bluff to a level area at the edge, bordered by a low rock wall. A tower with 50 steep stone steps is another popular viewpoint. 

  • Parking: There is a paved parking lot with two accessible parking spots. The road to the summit is very curvy. 
  • Amenities: Accessible restrooms, picnic tables, and water fountain. 
  • Additional features: A visitor center is open seasonally. There are exhibits outside of the visitor center with historical information about the area.

Obstruction Pass State Park

Obstruction Pass is a small gem for those seeking the atmosphere of a wilderness escape. Situated at the far southeastern tip of Orcas, Obstruction Pass offers 80 acres of parkland to explore plus 10 primitive campsites. The main trails run well under a mile through lush vegetation and forest.

The easterly trail leads to a 150-yard beach unique in the islands, covered with marble-sized multicolored pebbles—as well as views of Lopez Island, Blakely Island, and Obstruction Island. The westerly trail ends in a panoramic water view and great picnic site.

Accessibility

Unfortunately, the trails are quite inaccessible. The Sound View trail is very faint and difficult to follow, and the surface can be challenging. The beach trail is very rocky with some steep sections and sharp drop offs. Access to the beach requires going down steep stairs, which may have a high drop from the bottom step onto rocks or driftwood. 

  • Parking: Gravel parking lot with one paved accessible spot. 
  • Amenities: Accessible vault toilet at the trailhead, vault toilet at the campground near the beach. No water.

The distinctively shaped Turtleback Mountain is a much-loved area for hikers—at 1,520 feet, the second-highest summit in the islands. For hikers and nature lovers, that translates into fantastic views and fascinating flora and fauna. The south-end approach, up the turtle’s “head,” is for those willing to tackle a steep ascent. You’ll enjoy wide-open vistas for much of the climb, but this also means more exposure to the sun.

For those less inclined to pant up an exposed climb, choose the north ascent. Here, conifer forest and wetlands replace the grasslands and Garry oaks of the south face.
