About 5 kilometers south of Galle, Unawatuna stretches along a crescent-shaped bay on the southwestern coast of Sri Lanka. Known for its sheltered waters, coral reefs and lively beach atmosphere, it is one of the most visited beaches in the country.

Why visit Unawatuna

Unawatuna owes its popularity to a combination of assets: a protected bay ideal for swimming, reefs accessible by snorkeling from the shore, a diveable wreck offshore, and a concentration of restaurants, guesthouses and beach bars that make it a comfortable base after a day exploring Galle. The wooded hill of Rumassala, which closes the bay to the northwest, adds a natural backdrop to the scene and shelters several secondary sites.

The beach suits both travelers looking for a beach stopover at the end of their trip and divers exploring the sites of southwestern Sri Lanka.

History and evolution of the bay

Until the 1990s, Unawatuna was a fishing village set against a beach renowned for the quality of its water and coral barrier. The tourism boom of the 2000s multiplied guesthouses, hotels and shops, permanently transforming the village's character.

The December 2004 tsunami struck the southwestern coast hard, and the bay was not spared: loss of life, destroyed infrastructure, damaged reefs. Reconstruction was accompanied by accelerated coastal erosion, which led to the installation of breakwaters to retain sand. These structures, along with tourism pressure on the corals, remain a subject of debate. The coral barrier persists but remains fragile, encouraging respectful snorkeling (no vigorous fin strokes on coral, no collection of specimens).

What to see and do

The beach and swimming

The curve of the bay limits the swell, making swimming safer than elsewhere on the southern coast. However, some areas remain exposed to currents at the reef edge: it's best to ask locals before venturing far.

Snorkeling and scuba diving

The coral reefs of the bay can be explored by snorkeling directly from the shore. For scuba diving, several centers run excursions to nearby sites, including the wreck of the SS Rangoon, a British steamship that rests offshore from the bay. It is one of the historic diving sites in the southwest.

Jungle Beach

At the far northwest end, a small hidden beach called Jungle Beach is reached by descending a path through the wooded hill of Rumassala. The site is quieter than main Unawatuna and is ideal for snorkeling on the coral close to the shore.

Japanese Pagoda and Rumassala

On the same hill stands the Peace Pagoda, a Japanese structure, one of the white stupas built by the Nipponzan-Myōhōji order after the war. The Rumassala sanctuary, linked in local tradition to the Ramayana, is worth visiting nearby. Allow half a day to combine Jungle Beach, the pagoda and Rumassala.

Surfing

Waves at Unawatuna remain modest. Experienced surfers head to Hikkaduwa, about twenty kilometers to the north, whose breaks are better exposed.

Practical information

• Duration of visit: half a day for the beach alone, two to three days to enjoy water activities and excursions to Galle.
• Equipment rental: masks, fins and boards are available for rent on site from diving centers and hotels (moderate rates).
• Diving: several PADI or SSI certified centers; the rate for a two-dive excursion is in the upper-middle range of the country given the wreck dive.
• Swimming safety: no systematic lifeguard presence; ask your hotel for advice on areas to avoid, especially after monsoon downpours.
• Accommodation: wide range of guesthouses, boutique hotels and resorts. Booking recommended during high season.

When to visit

The southwestern coast experiences its dry season from December to March, the optimal period for swimming, snorkeling and diving. It is also high tourist season, with significant crowds and higher prices. The shoulder months (November, April) offer good conditions with fewer visitors. From May to September, the southwest monsoon makes the sea rough and underwater visibility poor.

How to get there

Unawatuna is approximately 130 kilometers south of Colombo and 5 kilometers from Galle.
