Bladium Sports & Fitness Club, located in the Naval Air Station in Alameda (seemingly the last place you'd expect a sports facility to be situated), is a huge facility housing several fields. There is a soccer field, inline hockey rinks, several volleyball courts, basketball courts, batting cages,a fitness center, and even a rock wall if wall climbing's your thing. In short, this place has got it all. To top it off, there's even a sports bar and a children's center. So if you're looking for an indoor environment to play recreational sports late at night (they're open late: until midnight on weekdays and until 10 pm on weekends), Bladium is the place to go.
