Dive-site story
Situated along the southern coast of Matara, Polhena Reef features a protected inshore lagoon that slopes gently out to an offshore barrier. Divers navigate scattered coral bommies, sandy gullies, and rocky outcrops that host resident green sea turtles grazing on algae beds. The sheltered inner reef transitions into a livelier outer slope where schools of reef fish take shelter from coastal currents.
Frequent encounters with resident green sea turtles feeding along the shallow reef flats
Expansive hard coral formations interspersed with sandy patches harboring rays and moray eels
Calm entry conditions inside the natural reef barrier during the southwest diving window
Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
Calm sea conditions and optimal visibility align with the northeast monsoon period when the southwest coast is sheltered.
