Things to do · Destination Guide
Two dive coasts, historic Galle wrecks and a living fort on one southwest Sri Lanka trip
Pick an activity mode to compare signature sites, skill fit, and gear planning notes before you lock your trip.
Dive from the Unawatuna/Galle area for mixed-depth rock reefs and the Rangoon and SS Orestes wrecks, or arrange separate Hikkaduwa departures for The Conch, Earl of Shaftesbury and offshore rocks. Divinguru describes about 16 Unawatuna sites, while the Sri Lanka Sub Aqua Club inventories different Hikkaduwa wrecks. This is not a single interchangeable boat circuit. The latest Divinguru notice sets the 2026-27 Unawatuna season at 1 November to 10 April; Hikkaduwa operators must confirm their own daily launch plans.

Rangoon Wreck
A Galle/Unawatuna-side wreck described by Divinguru around 30 m.
SS Orestes

The Conch
A separate Hikkaduwa wreck.
Operator Checklist
Contact the actual Unawatuna or Hikkaduwa provider for date, location, operating boat, certification minima, insurance, equipment, oxygen and evacuation procedures. Divinguru's current season starts 1 November 2026, although an older PADI listing uses 15 October. Ceylon Nautica advertises year-round sites but provides no dated departure calendar. Some wrecks need archaeology or Navy approval; do not enter archaeological wrecks, penetrate structures or collect artifacts without explicit authorization and appropriate training. A Ceylon Nautica generic overnight-vessel product is not evidence of a Galle/Hikkaduwa dive-liveaboard circuit.
