Discovering Elk Rock Island: Milwaukie's Hidden Natural Treasure
Tucked just off the shores of downtown Milwaukie lies one of our city’s most magical and meaningful places—Elk Rock Island. If you’ve never been, you're in for a treat. And if you have, you probably already know just how special this spot is to our community, our history, and our ecosystem.
A Little Island with a Big Story
Elk Rock Island isn’t just another park—it’s actually a volcanic island made of 40-million-year-old basalt, some of the oldest exposed rock in the entire Portland metro. That’s right, you’re basically walking on ancient lava flows when you visit. It feels like stepping into a different world… one where the Willamette River winds peacefully around you, and the city fades into the background.
But the island’s history is just as rich as its geology. Back in the early 1900s, it was part of Milwaukie’s social scene—home to a speakeasy-style dance hall (yes, on an island!) where locals would gather to cut a rug during Prohibition. Though a fire eventually ended its party days, the island stayed in private hands until it was gifted to Portland, and later transferred to the City of Milwaukie in 2016. Since then, it’s been lovingly cared for by local volunteers and environmental stewards.
What Makes It So Special?
Elk Rock Island is more than a great place for a walk or a paddle. It’s home to seven different habitat types, from lush riparian forests to dry oak woodlands and even seasonal vernal pools that support frogs, salamanders, and rare plants. You’ll find one of the last Oregon white oak stands in the region here—and if you visit in spring or summer, there’s a good chance you’ll spot bald eagles, osprey, cedar waxwings, and all kinds of wildflowers.
This place plays a huge role in local conservation efforts too. Groups like the Milwaukie Parks Foundation, Friends of Elk Rock Island, and regional partners have worked hard to remove invasive species, replant natives, and restore the riverbanks to support fish like salmon, steelhead, and lamprey. It’s a wild place in the middle of our city—an urban sanctuary that supports everything from tiny insects to giant birds of prey.
Visiting the Island
You can reach Elk Rock Island by heading to Spring Park (SE 19th Ave & Sparrow St). From there, it’s a short walk down a wooded path to the land bridge that appears during lower river levels (typically late spring through fall). Just be sure to check water conditions—at certain times of year, the island is truly an island!
There aren’t any fancy amenities on the island—and that’s part of the charm. It’s rugged, peaceful, and full of surprises. Bring your water bottle, wear good shoes, and leave no trace. There’s a playground and picnic area at Spring Park if you’re coming with family or just want to chill after your hike.
How You Can Help
If you love this place like we do, consider getting involved! There are regular volunteer work parties throughout the year where you can help pull ivy, plant native flowers, or just learn more about what makes the island tick. Keep an eye on events hosted by the City or the Milwaukie Parks Foundation, and bring a friend—you don’t need experience, just a pair of gloves and a love of nature.
Elk Rock Island is part history, part wilderness, and 100% Milwaukie. Whether you're birdwatching, hiking, volunteering, or just soaking in the views, this little island is a reminder of how powerful it is when a community comes together to protect the wild places we all love.
See you on the trail!
