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 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 gathered during Prohibition. Though a fire eventually ended its party days, the island remained privately owned 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 unique habitat types, including lush riparian forests, dry oak woodlands, and seasonal vernal pools that support frogs, salamanders, and rare plants. You’ll also find one of the last Oregon white oak stands in the region here. In the warmer months, you might spot bald eagles, osprey, cedar waxwings, and wildflowers in full bloom.
It’s also a vital hub for local conservation efforts. Groups like the Milwaukie Parks Foundation, Friends of Elk Rock Island, and regional partners work year-round to restore native ecosystems, remove invasive species, and support fish populations like salmon, steelhead, and lamprey. This island is a thriving, wild sanctuary in the middle of our urban landscape.
Visiting the Island
To visit, head to Spring Park (SE 19th Ave & Sparrow St). From there, a short wooded path leads to the natural land bridge that appears during low river levels (typically late spring through fall). Be sure to check water conditions beforehand—in winter and early spring, Elk Rock really is an island!
There aren’t any built amenities here—and that’s part of the magic. It’s rugged, peaceful, and full of quiet beauty. Wear sturdy shoes, bring water, and leave no trace. Spring Park also has a playground and picnic area, making it a great spot to spend the day with family or friends.
Make It a Day of Adventure
If you’re planning to explore Elk Rock Island, why not pair it with one of Milwaukie’s biggest summertime events? On Friday, August 2nd from 10 AM – 8 PM, The Little Float will take over Milwaukie Bay Park—just a stone’s throw from Elk Rock. Expect music, food trucks, paddle sports, vendor booths, and community fun on and off the water.
It’s the perfect excuse to make a full day of it—start your morning with a hike out to Elk Rock Island, then head over to the park to enjoy the festivities. You can learn more and grab your tickets at www.little-float.com.
How You Can Help
Love this island like we do? Join a volunteer work party! Whether you're pulling ivy, planting native flowers, or learning about local wildlife, it’s a great way to connect with the land and the people who care for it. Keep an eye on events from the City of Milwaukie and the Milwaukie Parks Foundation, and bring a friend—you just need gloves and a love of nature.
Elk Rock Island is part history, part wilderness, and 100% Milwaukie. Whether you’re birdwatching, hiking, volunteering, or celebrating at The Little Float, this hidden gem reminds us what’s possible when a community comes together to protect the places we love.
