Last one in's a rotten egg! We're finding the best places in the world to stick our toes in this summer (or next winter) for our World's Coolest Pools map. Know of any pools we must check out? Let us know.
Get your entire workout in in two turns or less: San Alfonso del Mar resort's pool has been officially recognized by the Guinness book as the largest pool in the world at over a kilometer in length running along the Pacific Ocean.
Fed with over 250,000 cubic meters of sea water, San Alfonso's pool just south of Valparaiso opened in 2008 after five years and $3 billion in construction costs. Kept at a balmy 79 degrees year round, it's even primed for swimming in the Southern Hemisphere winter -- or you could just laze on one of its private beaches or paddle the length on a rented boat. Just don't let go of your water wings, or you may never see them again. ]]>
