Seattle's most manicured park sits atop Capitol Hill and is named for US volunteers in the 1898 Spanish-American War. While wandering among its leafy glades, check out the glass-sided Victorian conservatory, filled with palms, cacti and tropical plants; climb the water tower; visit the Asian Art Museum; and don't depart before you've taken in the opulent mansions that grace the streets immediately to the south.
