The Pacific Northwest has countless spots where you can look around and say “Wow, I love it here!” Seriously, every view is different and beautiful. It’s also a place where kids can run wild and play on the beach (almost year round). Fort Casey on Whidbey Island is such a place. From forest trails to bunkers overlooking beaches, a day at Fort Casey is fantastic fun.
Locale of Fort Casey State Park
There are two ways to get to Fort Casey State Park: driving west from Interstate 5 or taking the Port Townsend ferry. If you’re coming from Seattle or Vancouver, you’ll be coming from I-5. If you’re already having a fantastic trip on the Olympic Peninsula and want to jaunt to the east sound, you can do that too!
Our last trip to Fort Casey was after spending a fun summer weekend in Anacortes. After spending a few days sailing and playing in some awesome parks, we left Anacortes a bit early to be able to spend some time exploring Fort Casey with the kids. It was a great addition to an already fun weekend and a great activity to wear the kids out before our ferry ride back to our side of the Puget Sound.
Tip: if you’re traveling via the Port Townsend ferry and it’s the weekend, check to see how the ferry traffic is. The boats on this route are small and they do offer reservations if you’re worried about missing the boat.
What to do at Fort Casey
Like we said, there’s tons to do at Fort Casey State Park. When I was in 5th Grade, this is where we did our overnight camp. We got to stay in the military bunk houses and learn about survival in the woods, as well as just have fun and be kids. Such a cool experience as a kid!
Bunkers
The bunkers at Fort Casey are pretty cool. From concrete lookouts with sweeping views (and scary staircases) to mazes deep within the hills that you should only go into if you’re exceptionally brave and totally not scared of the dark. We enjoy doing the more shallow bunkers and checking out the cannons, but our oldest, Oliver, loves doing the scary ones. He’s a brave little soul.
Note: DO NOT MAKE CHILDREN GO INTO THE BUNKERS. When I was little I was forced to go into the bunkers and it was terrifying; a bit scarring actually. Don’t make your kids do it if they don’t want to. This is totally a “No means ‘no’” situation.
Tip: if you’re interested, there are bunker tours available. Check with the State Park website for details.
Beaches
There are also designated fire areas at Fort Casey. Washington has varying laws about when and where you can have beach fires, so it’s nice that it’s clear here. There are limited beach fire ares though, so don’t bank your entire trip on getting to do one. We didn’t do a beach fire on our last trip, but we’ve done them before.
And then swimming… My goodness the water is beautiful, but dang! It’s cold 95% of the time. You totally can swim if you’re into that though. Beware of the drop off though, as the beach, depending on the area, drops off quickly and the tide is strong in Admiralty inlet.
Tip: when you’re in the Puget Sound area, or any coastal area for that matter, keep a few beach toys and a blanket in your car. You’ll be glad you have them then you randomly find a perfect beach.

Things to know about Fort Casey
Growing up, we went to Fort Casey a lot. True, when I was a kid I hated it because it meant being forced to go into dark bunkers and get the bejeebers scared out of me, but as an adult I can fully appreciate all aspects of the Park. Our kids enjoy the full experience and will, I’m sure, always love popping in and out of the bunker mazes.
If you’re in Seattle and you’re looking for an unusual day trip, head north to Whidbey Island and check out Fort Casey State Park. You’ll have a great time and get plenty of fresh sea air… and maybe even some exercise!



I love a stop that offers such diversity of activities combined with education. Will have to check this out next time we pass thru!!
Wow! I love the driftwood on the beach! I want to go here! Perfect picnic beach 🙂
It’s nice to see beach pictures that don’t involve crowds of people lying in the sand!
Wow! I was in this neck of the woods last summer and totally missed all this. Thanks for giving me a reason to go back.
