Why dive here
With 121+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, orcas and seals & sea lions - OLGA offers some of West Coast (Gothenburg)'s richest wreck diving. Water ranges 3-18°C, warmest July, August, September.
The Olga wreck, a fishing vessel that went down in 1953, offers a solid dive for those exploring Sweden’s West Coast. It’s pretty broken up now, but you can still make out the bow and stern, with the midship section mostly collapsed. We’ve found plenty of cod lurking in the shadows, along with wrasse darting between the metal plates. It’s a good spot for a relaxed dive, not too deep, and typically has decent visibility, making it suitable for divers comfortable with wreck penetration, though there isn't much left to get truly inside. Just keep an eye on the local boat traffic if you're planning a surface swim.
Safety Notes
Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
Cold water this month (avg 13°C). Drysuit or thick wetsuit (7mm+) recommended.
