We had such a great weekend camping in the Memory Maker! Danielle has thought of everything when it comes to making life easy while you are “roughing it”. We felt cozy and comfortable sleeping as a family of 5. It was easy to pull behind our Tahoe as well. Great experience all around, we already have our next trip booked!

Danielle is a great host! The trailer was wonderfully laid out and perfect for a family of four. It was very clean and everything worked perfectly! Our family had a great time and would definitely rent from Danielle again!

How to get to Jarrell Cove State Park

Jarrell Cove State Park sits on the north end of Harstine Island, reached by the Harstine Island Bridge from Pickering Road off State Route 3. From Olympia, the drive is roughly 25 miles and about 45 minutes; from Tacoma, expect 40 to 50 miles and around an hour; from Seattle, plan on about 80 miles and 90 minutes. RV drivers should note the island's narrow, winding, tree-lined roads and some tight turns near the park entrance, which can be challenging for larger rigs. The nearest major airport for fly-and-rent trips is Seattle-Tacoma International Airport (SEA), about 70 miles northeast.
