Why dive here

The Silvia De Grass wreck in the Pacific Northwest is a deep, cold water dive, definitely one for the experienced wreck divers among us. We’ve found it’s a good choice when you’re looking for something a bit more challenging than the usual reef dives. The wreck itself sits upright, mostly intact, which means plenty of penetration opportunities if you’re properly trained and equipped. Expect to see wolf eels peeking out from dark corners and greenling darting through the superstructure. It's a real dive into history, albeit a chilly one, so good drysuit skills are a must.
