These public gardens are regularly open to visitors, some all year long and others on a seasonal basis. Most of these gardens are open dawn to dusk and have free admission. About one-third have a modest entrance fee.

*An arboretum or botanical garden is a place where plants are grown (trees, shrubs, vines, herbs, perennials, etc.), often for scientific or educational purposes, as well as for display and enjoyment by visitors. Most gardens have a focus in the types of plants they grow. Examples include: native plants, natural forests, cultivated or wild gardens, woodland gardens, wetlands, and English or Asian gardens, to name a few. Others may offer several different types of these and other gardens within their landscape.
About Garden Tours
Many of the gardens in the following lists encourage free self-guided tours by providing signs, maps, and guides which you can download from their website or pickup when you arrive.
Some of these Puget Sound gardens also offer docent-led guided tours. (A docent is someone trained to be a guide. Most, if not all docents at these gardens are volunteers who simply love gardens and want to share knowledge with others.)
Some of the guided tours are also free, but donations are gladly accepted. All gardens appreciate donations to help defray costs.
Following the list of gardens in Seattle, Tacoma, and other cities throughout the Puget Sound region, you’ll find an event calendar of upcoming docent-led garden tours.
