    Atrevida Reef, tucked away in the Pacific Northwest, is one of those spots that reminds us why cold water diving is so special. Forget your preconceived notions of barren rock; this place is alive. We love dropping in to find the reef carpeted in a thick, vibrant layer of anemones – the strawberry anemones really pop with their brilliant reds and oranges. It’s a sensory overload, seeing the sheer density of life clinging to every surface. Our favourite time to dive Atrevida is on a slack tide, ideally just after a good rain has settled some of the suspended particles. That's when visibility can stretch out to a good 15 metres, letting you really appreciate the scale. Keep an eye out for the smaller stuff too; we've spent ages just watching the Sidestriped Shrimp darting between crevices and the Plainfin Midshipman hunkering down on the bottom. If you’re lucky, you might even spot a Spiny Dogfish cruising by in the deeper sections. It’s a site that rewards a slow, observant dive, perfect for photographers or anyone who appreciates the intricate beauty of temperate reefs.
