    The Sentier marin archéologique d'Olbia is a bit different from your usual Medes Islands dive. It’s an archaeological trail, not just a reef. We’ve found bits of Roman pottery and old amphora fragments scattered amongst the rocks, which makes for a neat treasure hunt. You’ll also spot the usual Mediterranean suspects - damsel fish flitting around, maybe a cowfish or two tucked into the seagrass. It’s a good choice for when the wind is up and you want something sheltered, or for divers who appreciate a bit of history with their dive.
