Visitor Comments, Memories and Reviews
June 4 Mosquito nightmare by Mozzies
Beautiful park, well maintained. Mosquitoes are so bad, we left early. Even got eaten through our clothing! Never again! Shame as the park is beautiful with large lots.
May 14 Dont forget your bug spray!!
We tent camped in one of the primitive sites. The campsites are spacious. Campground is clean. Pit toilets were suprisingly clean. However, the park makes you buy shower tokens..only to find out the shower was broken. Plus..the mosquitoes were horrible. Seriously..pack your Deet! If you camp before June..bring extra blankets! Super cold at night.
August 22 We will come back by E. Brink
With only a 3-4 hour drive from the Seattle Area this makes for a great destination to find some warm sunny boating weather. This was our first time to the reservoir and we enjoyed our time swimming and boating. Unfortunately we were notified of toxic algae after our first day of swimming. We were advised not to swim or boat in the water and to take showers after any water activity. We continued to swim and play in the water however we did not let our dogs join us so one person had to stay at camp and play dog sitter. The bees were really bad this year so I highly recommend carrying wasp traps in your camping gear.
July 15 Mosquito Haven by stonetrails
The miniature, winged, blood-sucking, vulgarities are abundant and thirsting for your soul. I needed a transfusion after my visit.
June 17 Great!
I have gone for year they keep improving the park and it is a great place to swim and fish.
