More Getaways.
More to Come Back To.
The best getaways have a way of becoming traditions. A favorite spot to park the RV. A familiar face at a community BBQ. An afternoon outside that turns into a memory your family talks about for years.
At O’Sullivan Sportsman Resort, membership starts with that feeling of belonging. Join a community of RV travelers and outdoor enthusiasts who make time for adventure, relaxation, and good company.
Set in Washington’s Columbia Basin, surrounded by lakes, sand dunes, and rocky canyons, O’Sullivan offers a setting worth returning to—whether your ideal day is full of activity or wonderfully unhurried.
Adventure When You Want It.
Peace When You Need It.
Some days call for getting out and exploring. Others call for slowing down. Make room for both.
Make Time for Adventure
Let the Columbia Basin inspire your next outing, from time on the water to exploring the region’s distinctive desert landscape.
Follow Your Favorite Pastimes
Build your getaway around fishing, outdoor recreation, and the activities you love—or leave the schedule open and see where the day takes you.
Enjoy Being Together
