My daughter and I camped at Dosewallips State Park and woke up to a herd of elk tromping through the woods in the morning. After enjoying some hot cocoa and oatmeal, we took a short hike in Fallsview Canyon before catching the ferry home.
Dosewallips is a nice little campground that works well for family car camping trips. It's was exactly what we were looking for on this particular weekend: Easy drive (right off Hwy 101), semi-private wooded campsite with a flat parking spot, and close to several family-friendly hikes. On a very cold but clear Saturday night in November, most of the sites were available. There is elk poop everywhere, but that’s OK because there are elk everywhere too!
Fallsview Canyon is a good kiddo hike. As a standalone hike, I don’t think it’s worth a trip from the Seattle area, but tacked on to a weekend camping trip it was perfect. The trail was in great condition with only a couple blowdowns that my 5-yr old daughter could easily navigate.
