Beautiful lake that you can swim, float, paddle board, snorkel, or fish in. Lots of picnic areas, pavilions, and a kitchen you can reserve. Hiking and biking trails. Playground. Spacious bathrooms with showers. Camping areas. Requires a Discover Pass. $10 for a day pass or $30 for a year (good at any WA state park). Dog-friendly! My 4 yr old had a blast in the water. Water was a comfortable temperature and felt amazing on 80° day. I lived near here for the last 5 years and can't believe this was my first time there. We are definitely going back with our dogs and planning a camping trip also. Large lake, so lots of places to enjoy peace and quiet as well.
