South Iron Rock
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - South Iron Rock offers some of Alaska's richest diving. Water ranges 5-15°C, warmest July, August, September.
Diving South Iron Rock in Alaska means pulling on a thick drysuit and bracing for a chilly but rewarding experience. The main draw here is the sheer rock face, dropping straight down, covered in cold-water anemones and sponges. We've seen some impressive sunflower stars clinging to the rocks and the occasional spotted ratfish cruising by. It’s a dive for those who appreciate the unique beauty of temperate waters, a chance to spot species like the sidestriped shrimp and perhaps even an orca passing through if you're lucky. Not for the faint of heart, but genuinely captivating.
Safety Notes
Cold water this month (avg 11°C). Drysuit or thick wetsuit (7mm+) recommended.
