    Ao Luek is one of those Koh Tao spots we keep coming back to. It’s got a bit of everything, but what truly stands out are those incredible staghorn coral fields, particularly as you get into the shallows. The light dances through them, creating these fantastic shadows, and you’ll often find juvenile fish flitting in and out. We’ve had some cracking encounters with blue-spotted stingrays tucked into sandy patches here, and the Eye-spot butterflyfish seem to love the place. The topography is interesting, a mix of rocky outcrops and sandy channels, which keeps things varied as you fin along. We’d suggest going early if you can manage it; the mornings usually offer calmer conditions and fewer boats. It’s a pretty relaxed dive, perfect for working on your buoyancy or just enjoying the slow pace. Keep an eye out for the cleaner wrasse stations; they’re always busy. While the deeper sections have their charm, it's those sun-dappled coral gardens in the shallows that truly make Ao Luek our favourite.
