Over the years, my family has enjoyed stunning vistas from Washington's ferries.If you want to see a nice view of Washington, try a ferry ride. Amanda Adler When my son was younger, we used rides on Washington's ferries as sightseeing excursions.On a clear day, the ferry between Seattle and Bainbridge Island offers unmatched views of the city's skyline. Its price tag about $10 per adult, kids are free also makes it much more affordable than seeing the city on a land-based tour.On a recent visit to Olympic National Park, we took a ferry to an island with great views and access to outdoor adventures.We took a ferry out of Olympic National Park. Amanda Adler Now that my son is a tween, he loves more active adventures.While planning a recent hiking trip through Washington's Olympic Peninsula, we decided nearby Whidbey Island would be the perfect place to extend our stay and enjoy even more sightseeing and other outdoor activities. To get there from Olympic National Park, we would take a ferry that allowed us to take our rental car with us.The ferry ride from Olympic National Park to Whidbey Island only cost us $21.We drove our car onto the ferry. Amanda Adler To get from the park to Whidbey Island, we took the ferry from Port Townsend to Coupeville.I booked the ferry passage online for my three-person family and our rental car and was pleasantly surprised to see that our one-way trip was only $21.Driving onto the ferry was a smooth, well-organized process that only took a few minutes.Once parked on the ferry, we weren't confined to our car.From the deck, we were able to spot seabirds and seals. Amanda Adler Once our car was all set, we headed up to the ship's deck area. The ferry's great indoor and outdoor sightseeing options allowed us to view birds, seals, and other wildlife. We also enjoyed watching Washington's rugged landscape pass us by. The ship also had a small snack shop, where my son purchased chips and a sports drink.We had a great time once we docked, too. Whidbey Island was fun to explore. Amanda Adler After about 30 minutes, we docked at Whidbey Island, which also proved to be a great spot for sightseeing and wildlife viewing.First, we explored downtown Coupeville's cute boutiques, art galleries, and restaurants. From the town pier, we spotted even more seals swimming close to shore. At one point, we passed a printed guide showcasing whales in the region next to a bell to ring if any were spotted.After eating some fresh seafood, we drove about 30 minutes to Deception Pass State Park.While on the island, we continued to immerse ourselves in nature. Deception Pass State Park was beautiful. Amanda Adler The island's picturesque state park also offered ample wildlife viewing opportunities.At Deception Pass State Park, our one-day parking pass was only $10. My family had lots of time to explore, birdwatch, hike, paddle, and soak up the scenery.Lastly, we did a pricey whale-watching tour that paled in comparison to our affordable ferry ride. We weren't super sold on the whale-watching tour, especially since we'd seen wildlife from our cheap ferry ride. Amanda Adler Wildlife sightings on land or a ferry are never guaranteed, so I'd also booked us a $300 whale-watching tour.Our tour was on the "mainland," so we drove up the bridge on the north end of Whidbey Island to get to the boat. It took us to San Juan Islands, an archipelago known for its orca-watching opportunities.Unfortunately, we only saw one orca during our four-hour excursion.It was beautiful, but the whale's distance from us, combined with the numerous other tour boats in the area all vying for a prime viewing position, made the experience feel crowded and sort of artificial.After this tour, I realized we preferred the more natural and spontaneous feeling of encountering wildlife during our ferry ride. We actually saw more animals from the ferry than we did on the tour. Even if we hadn't, we would've still gotten to enjoy beautiful scenery as we sailed through Washington.Spotting animals in the wild can be unpredictable, so I'd rather take my chances on a laid-back, inexpensive ferry instead of pricey excursions where tourists compete for the best views.
