Getting There & Parking

Navigating to Fort Casey State Park is part of the adventure, as Whidbey Island is accessible by bridge or ferry. For most visitors coming from the Seattle area, the most common route involves taking the Mukilteo-Clinton ferry. This scenic 20-minute ride across Puget Sound drops you on the south end of Whidbey Island, from which it's about a 30-minute drive north to the park. Alternatively, if you're coming from the Olympic Peninsula, the Port Townsend-Coupeville ferry provides direct access to the central part of Whidbey Island, placing you just a short drive from Fort Casey. We always recommend checking the Washington State Ferries website for current schedules and making reservations, especially during peak season, as wait times can be significant.

Once you arrive at Fort Casey State Park, you'll find ample parking available. There are several designated parking areas throughout the park, including lots near the main gun batteries, the lighthouse, and the campground. A Discover Pass is required for vehicle access to Washington State Parks. As of our last check, a one-day Discover Pass costs $10, while an annual pass is $30. You can purchase these passes online, at most park entrances, or at local retailers. We recommend purchasing an annual pass if you plan on visiting multiple state parks during your trip to Washington. Parking is generally well-organized, but during busy summer weekends, the most popular lots can fill up, so arriving earlier in the day is always a good strategy to secure a spot close to the main attractions. Our team finds that arriving before 10 AM or after 3 PM usually provides the best parking experience at Fort Casey State Park.

Top Things to Do

When you visit Fort Casey State Park, you'll quickly discover that there's a wealth of activities to fill your day, blending history, nature, and recreation. Our team has highlighted the top things to do at Fort Casey State Park to help you prioritize your visit:

• Explore the Historic Fortifications: The primary draw for many is the chance to wander through the massive concrete batteries built to protect Admiralty Inlet. Battery Worth and Battery Moore are particularly impressive, with their enormous disappearing guns (though the original guns are no longer present, replicas provide a sense of scale). We encourage visitors to climb the stairs, explore the underground rooms, and imagine the soldiers who once manned these defenses. This is one of the essential things to do at Fort Casey State Park.
• Visit Admiralty Head Lighthouse: This iconic lighthouse, originally built in 1903, offers stunning views and a glimpse into maritime history. While the lighthouse itself is not always open for interior tours, the grounds are accessible, and it’s a fantastic spot for photography, especially at sunset. Check with park staff for current opening hours for interior access.
• Beachcombing and Tidepooling: The park’s shoreline along Admiralty Inlet is perfect for a leisurely stroll. At low tide, the rocky beaches reveal fascinating tide pools teeming with marine life. Keep an eye out for sea stars, anemones, and hermit crabs. It’s a peaceful activity and a great way to connect with the natural environment.
• Birdwatching: Fort Casey is a designated Important Bird Area (IBA), making it a haven for birdwatchers. The diverse habitats attract a wide array of species, including various seabirds, raptors, and migratory birds. Bring your binoculars and look for eagles, ospreys, and numerous shorebirds.
• Picnicking: With its stunning views, Fort Casey State Park offers numerous scenic spots for a picnic. There are picnic tables available near the batteries and along the bluff, providing perfect vantage points to watch ships pass through the inlet and enjoy the Olympic Mountain backdrop.
• Kayaking and Paddleboarding: For those with their own equipment, launching a kayak or paddleboard from the park’s beach offers a unique perspective of the coastline and the fort from the water. The waters of Admiralty Inlet can be challenging, so this activity is best for experienced paddlers on calm days.
• Kite Flying: The open bluffs and consistent breezes at Fort Casey make it an ideal location for flying kites. It’s a popular activity for families and adds a vibrant splash of color to the skies above the historic fort.

Best Time to Visit

Our team has found that the best time to visit Fort Casey State Park largely depends on your priorities, but generally, the late spring through early fall offers the most pleasant weather and a full range of activities. From May to September, Whidbey Island experiences warmer temperatures, less rainfall, and longer daylight hours, making it ideal for exploring the fortifications, hiking, and enjoying the beaches. However, this is also peak tourist season, meaning larger crowds and potentially more competition for parking and ferry reservations.

For those seeking a quieter experience, we recommend visiting in the shoulder seasons of April or October. The weather can be a bit more unpredictable, with cooler temperatures and a higher chance of rain, but the park is significantly less crowded. You’ll still enjoy beautiful views, and the crisp air can make for invigorating walks. Winter visits (November to March) offer a stark, dramatic beauty, with stormy skies and powerful waves, but many facilities may have reduced hours, and some trails could be muddy. Birdwatching, particularly for wintering seabirds, can be excellent during these months. Ultimately, while summer offers the most reliable conditions, Fort Casey State Park holds a unique charm in every season, and we encourage you to choose the time that best suits your travel style.

Fort Casey State Park Hiking Trails

While Fort Casey State Park is renowned for its historical fortifications, it also offers several delightful opportunities for hiking, allowing visitors to immerse themselves in the natural beauty of Whidbey Island. Our team has explored these paths and can confirm that the Fort Casey State Park hiking trails provide a fantastic way to experience the park's diverse landscapes, from coastal bluffs to forested areas.

The primary Fort Casey State Park hiking trails are generally easy to moderate, making them accessible for most fitness levels. The most popular route is the network of trails that loop around the gun batteries and connect to the beach. This allows you to combine historical exploration with scenic coastal views. You can walk along the bluff overlooking Admiralty Inlet, offering expansive vistas of the water, passing ships, and the Olympic Mountains in the distance. These trails are well-maintained and provide excellent vantage points for photography and birdwatching.

Additionally, trails extend into the forested areas surrounding the main fort, offering a different kind of experience amidst the trees. While not extensive, these paths provide a peaceful escape and a chance to observe local flora and fauna. The total mileage of interconnected trails within the park is modest, typically ranging from 2 to 4 miles depending on how much you loop and explore. However, for those looking for a longer trek, the park connects to the larger Ebey's Landing National Historical Reserve, which offers the iconic Ebey's Landing Bluff Trail – a more strenuous 5.6-mile loop that combines beach walking with a dramatic bluff climb. While not strictly within Fort Casey, it's a very popular extension for hikers in the immediate vicinity. We recommend wearing comfortable walking shoes, bringing water, and checking weather conditions before heading out on any of the Fort Casey State Park hiking trails.

The park's accessibility, coupled with the charm of Whidbey Island, solidifies its position as a top-tier Washington State Park.
