I absolutely adore this park! camping and hiking in the summer, tubing in the winter, mushrooming in the spring. There is no time of year that is bad for this park.
My husband and I love this State Park. It was definitely a good, long drive to get to, but was so worth it (about 5 or so hours from Walla Walla). The campsite was close to showers and water, and not too close to others. Both tent and RV camping is allowed. The hiking trail was long and absolutely amazing, and we ended up near a fire cabin used during the winter and summer. There was a night where coyotes came very close to the campground, and the rangers took care to ensure they didn't get too close. Everyone we came into contact with was friendly and helpful. We saw so much wildlife since it's located far away from cities and people. So worth it!
