Volunteer Park Conservatory
Located in Seattle's 48.3-acre Volunteer Park, the beautiful, historic conservatory, completed in 1912, is one of the few remaining original Victorian glass houses in the country. Its five display houses are home to tropical plants, palms, ferns, cacti, and other seasonal plants. There is usually a $6 admission fee for adults, but admission is free on first Thursdays. Admission is always free for kids 5 and younger.
