Photography - I use my free time to take long walks (perk: easy exercise) and take photos of whatever looks interesting which is very relaxing. It motivates me to travel and discover new places...even if it's still within the same town. I've been asked to take photos of people, events and groups by friends and it's always a nice experience. I also put up my photos online on places like tumblr where they have been recognized by the tumblr community on several occasions.

Triathlon - Obviously a great source of exercise. Teaches you to expand yourself (time, goals, etc.) because you have to train for swimming, biking and running. Races are competitive, but the racers are also very friendly (perks of a somewhat niche sport). And then of course it's always a wow factor among others since races last from 15 miles ("sprints") to 140 miles (Ironman).
