Volunteer Park (1247 15th Ave. E., Seattle) on Capitol Hill gives you the best of both worlds. You’ll get gorgeous fall colors from the mature trees in the park, and if it starts to rain, you can always duck into the Volunteer Park Conservatory ($4 adults, kids under 12 free; free First Thursdays and Saturdays) to continue your shoot. Noguchi’s Black Sun also makes a graphic, sculptural backdrop.
