Sports Fishing, is a very popular pastime for both visitors and residents alike. The deepest water in the world, the Marianas Trench, is just east of Guam and the waters around Guam are hundreds of fathoms deep. A world record Blue Marlin, and still one of the world's largest at 1,173lbs, was caught just off Tumon in 1969 and large Marlin can still be caught all year round. Guam's surrounding waters offer an abundance of off shore gamefish including mahi mahi, wahoo and several species of tuna. Guam has a modern fleet of sports fishing boats available for half and full day charter.

Many visitors take a break from Guam's blue waters and enjoy exploring Guam's rugged hinterland, waterfalls, rivers and jungles. A number of tour companies offer hiking tours and there are regular local 'Boonie Stomps' and organised mountain bike sorties every weekend that visitors are welcome to join. Horse riding treks into Guam's wilderness areas are also available at the Southern Comfort Corral.
