Tsawassen Paintball(I know it's on the mailand but it's still relatively close), Stormin Norman's, Victoria Paintball Adventures
The ONLY downfall to this field is some of it's fields locations. During the West Coast winters and some of Spring wetness most of the fields are generally unplayable. The site has 4 courses, but on a rainy day you play on one or two. The refs are generally really good at holding up the rules and are really personable people. The customer service at TNT and (lets throw in one of the owners websites) www.horizonpaintball.com is absolutley unsurpassable. They dominate the island paintball scene with amazing fields and great rates. The membership idea (which gets you 20% off all paint) is a HUGE plus. The rules at TNT are safety oriented, and the lecture about them is usually told by someone who can put humor into the speech. Pump play at this field, I find, is a lot more fun, cause when you're running around at VPA it's a lot more close quarters and even the rentals end up unloading on you. This is not to say the rentals and speedball markers and everything in between aren't fun at this field, but that this is probably the best pump play you'll find on Vancouver Island. Very laid-back friendly environment.
