🏝️ A Wild Island in the Columbia River — Portland’s Secret Campground Accessible Only by Boat — Government Island State Recreation Area in the Columbia River near Portland, Oregon, boat-access island, primitive camping, sandy beaches, wildlife wetlands, bird watching, kayaking — Multnomah County, OR
Portland has a million-acre metro area. Government Island is the 1,784-acre piece of it you can’t reach by car. Sitting in the Columbia River between Portland and the airport, this boat-access island offers primitive camping on sandy beaches, cottonwood forests, and wetlands that support herons, eagles, and osprey — all within sight of the city skyline.
You need a boat to get here, and that’s the whole point. The island filters visitors by commitment. No bridges. No roads. No developed facilities. Just beaches, forest, and the Columbia River flowing past on both sides. Camp on the sand, paddle the channels, and watch planes land at PDX while you sit on the wildest piece of land in metro Portland.
What to Do
| Activity | Details |
|---|---|
| Primitive Camping | Camp on the island’s sandy beaches — bring everything you need and take everything you leave. No facilities, no water, no trash cans. The camping is free and first-come. The experience is sleeping on a river island within sight of a major city — civilization on the horizon, wildness underneath you |
| Kayaking | Paddle the channels between Government Island and the smaller surrounding islands — the sheltered backwaters are calmer than the main Columbia. Watch for blue herons in the shallows, osprey hunting above, and beaver lodges along the banks. Launch from nearby mainland ramps |
| Wildlife | The island’s wetlands and cottonwood forests support great blue herons, bald eagles, osprey, red-tailed hawks, deer, and beaver. The island is important habitat precisely because it’s undeveloped — the wildlife thrives where the people can’t easily reach |
| Sandy Beaches | Long sandy beaches on the island’s south side — sunbathe, swim (with caution — the Columbia has currents), and watch the river traffic. The beaches face the Oregon side and catch afternoon sun. In summer, the sand warms and the water reaches swimmable temperatures |
| Fishing | The Columbia River around the island holds salmon, steelhead, sturgeon, and walleye — seasonal runs bring different species throughout the year. Fish from the island’s shore or from a boat anchored in the channels. Oregon or Washington fishing license required depending on which side you fish |
The Island
| Feature | Details |
|---|---|
| Location | In the Columbia River between Portland International Airport and the city of Portland — the island is visible from I-84 and I-205. The juxtaposition is surreal — a wild, forested island sitting between an interstate highway and an international airport |
| Access | By boat only. Launch from Chinook Landing Marine Park, Lewis and Clark State Recreation Site, or other Columbia River access points. The crossing is short but requires awareness of commercial river traffic and currents. Motorboats, kayaks, and canoes all work |
| History | Named because the U.S. government used the island for military purposes. Lewis and Clark passed this spot in 1805. The island has been a recreation area since 1964, preserved as undeveloped open space in an increasingly urban corridor |
| Undeveloped | No facilities. No water. No restrooms. No trails. No rangers. The island is managed as primitive recreation — meaning you’re responsible for everything. Pack it in, pack it out. Leave no trace. The island stays wild because visitors treat it that way |

Frequently Asked Questions
Do I need a reservation?
No — camping is first-come, first-served and free. There are no designated sites. Camp on the beaches. Popular spots fill on summer weekends — arrive Friday to claim a spot. Weekdays are nearly empty.
Is the Columbia River safe for swimming?
Swim with caution. The Columbia has currents, boat traffic, and cold water early in the season. The south-facing beaches have calmer water in protected areas. Never swim in the main channel. Watch children carefully. The river is powerful.
Make it a road trip: Pair a visit with Blue Lake State Park (a short drive away) or Willamette Stone State Heritage Site (a short drive away).
