Located along the beach at Lincoln Park, Colman Pool offers the best setting of any such facility in the city, hands down. You can have a picnic before or after you swim (see Best Picnic Spot), or just enjoy the view on the walk from the park entrance. The pool’s other great distinguishing feature is that it’s filled with heated salt water. Let’s face it, that’s probably the closest you’re going to come to dunking in sea water in this region, unless you belong to a polar-bear club or are trying to prove something. Kids will also enjoy the giant slide. NINA SHAPIRO 8603 Fauntleroy Way S.W. , 684-7494, seattle.gov/parks/aquatics/colman.htm
