Washington State Ferries are like really big boats that carry cars and people across the water between different places in Washington. Think of them like big, floating buses that drive over the water instead of on roads.
Just like you have to wait for a bus to come, you have to wait for a ferry to come too. Ferries run on different schedules depending on where they are going and when they start and finish for the day.
Once you get on the ferry, you can either stay in your car (if you brought it) or walk around inside the ferry. There are seats where you can sit and look out at the water or read a book, and there's a place to get snacks or drinks if you're feeling hungry or thirsty.
Ferries are important because they let people who live in different parts of Washington get to where they need to go. For example, if someone lives on one side of the water and works on the other side, they might take a ferry to get to work.
Overall, Washington State Ferries are a cool way to travel and see the beautiful water and scenic views of Washington.
