Outdoor pools are a bit of a rarity in the Pacific Northwest. Thank goodness for the Titlow Pool, part of the MetroParks Tacoma pool system. The pool, located in Tacoma's west end, is open annually from mid-June to the end of August. The outdoor, Olympic size, 50-meter pool, has a minimum depth of 3 feet and a maximum depth of 10 feet. There's a separate wading pool for little kids and lap lanes are open during all "open swim" times. It's clean, lifeguards maintain control, and shower facilities are adequate. A single swim for an adult is $3.50 (2.50 for kids 5 to 17). Punch cards are available at a savings.
