Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - GARM (POSSIBLY) offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The GARM is a deep one, lying at 54m, and a real treat for those with the training to get there. We’ve always had a soft spot for wrecks that feel like a snapshot in time, and this steamship, sunk by a U-boat in 1917, definitely delivers. Dropping down, you'll find the vessel largely intact, settled upright on the seabed. It’s a proper expedition, the kind where the light fades to an ethereal blue, and the wreck emerges from the gloom. The triple expansion engine is a favourite spot, still standing proud, heavily encrusted now with anemones and dead man’s fingers. You'll often find conger eels peering from the deeper recesses of the holds, and lobsters tucked into any available crevice. We’d suggest focusing on your trim and buoyancy here; there's plenty to penetrate for qualified divers, but it’s easy to stir up the fine silt. It’s a proper technical dive, and while there aren't many frills, the sense of history and the excellent preservation make it a genuinely rewarding experience for experienced wreck divers.
