Hole In The Wall

Hole in the Wall is a rocky coral outcrop featuring a mini mountain that rises from about 5–6 m to as deep as 18–20 m, with a short 1.5 m-wide swim-through at roughly 12 m. The reef top is shallow (around 8–10 m) and covered in colorful hard and soft corals, with whip corals and sea fans on the steep sides; one side drops into a vertical wall while the other slopes to sandy gardens. It is popular for its unique swim-through and abundant marine life, with large schooling fishes commonly seen around the channel. Dives are boat entries, typically beginning in well-lit shallow water around 8–10 m and descending down stepped drop-offs toward the tunnel at about 12 m, with overall depths generally from about 5 to 20 m. Currents are an important factor: the tunnel sits where ebb and flood meet, so moderate to strong currents and surge are common, especially during flood; diving near high slack tide and with a local guide is recommended. Visibility commonly ranges from about 10 to 20 m and water temperatures are tropical, roughly 26–29 °C. The ascent is made in open water or along the opposite wall with a safety stop in blue water. Hazards noted include venomous lionfish and scorpionfish, stinging hydroid colonies, and possible down-currents during flood, so good buoyancy control and attention to gear and guide instructions are essential.
