Take the light rail to Capitol Hill and enjoy a fountain, texture pool and reflecting pool, promenade paths, landscaping, a shelterhouse, a plaza, a children's play area, a wading pool, a lighted sports field, and a number of oversize chess boards!
The classic tourist spot! Take the light rail to Westlake, do some impulse shopping, and then take the monorail from there. While you're around, check out the Pacific Science Center, the Museum of Pop Culture, and of course, the iconic Space Needle.
