Galle is the main city on the south coast, approximately 1.5 to 2 hours away from Colombo via the expressway. Its heart is the Fort, an old town enclosed by ramparts, which was declared a UNESCO World Heritage site in 1988 as the "Old Town of Galle and its Fortifications".The Portuguese established a first fortification here in the 16th century, which the Dutch expanded from 1649 onwards; the sea wall was completed in 1729. The Fort covers around 52 hectares with 14 bastions, churches, a mosque, and colonial houses, which today host cafés, boutiques, and restaurants. The walls largely withstood the 2004 tsunami, which damaged parts of the modern city.Outside the ramparts lies the new town with its train station and central bus terminal, both within walking distance of the Fort. Most visitors stay and dine within the walls, for example, around Church Street and Pedlar Street.

Unawatuna is a seaside resort on a curving bay about five kilometers southeast of Galle and around 108 kilometers south of Colombo. Due to its proximity to the Fort and the coral reefs off the coast, it is one of the most visited beaches on the south coast.In front of the beach lie reefs and shipwrecks, home to fish and turtles. West of the bay rises the forested hill Rumassala, with the hidden Jungle Beach and the Japanese Peace Pagoda. The 2004 tsunami destroyed many beach restaurants; the development along the beach has since been rebuilt.Life unfolds along the beachfront promenade and in the alleys behind it; quieter accommodations are located towards Dalawella in the east.

Bentota is located at the mouth of the Bentota River, approximately 65 kilometers south of Colombo and 56 kilometers north of Galle. The seaside resort is known for its beach and water sports, and in the green hinterland are Lunuganga and Brief Garden, the two most famous gardens of the brothers Geoffrey and Bevis Bawa.The town lies on the southern riverbank; to its north is Aluthgama, whose railway station is served by most trains. Southwards follow Induruwa with a turtle station and further towards Galle, the Madu Ganga lagoon near Balapitiya.

Sri Lanka's south coast stretches from Hikkaduwa, about 100 kilometers south of Colombo, through Galle and the bays of Weligama and Mirissa, all the way to Tangalle. It connects a UNESCO-protected colonial city with surf beaches, fishing ports, and, further inland, some of the island's most renowned national parks.Most coastal towns are located along the coastal railway from Colombo to Matara and the A2 highway, making travel between them easy. Further inland lie the Sinharaja rainforest and the dry forests of Udawalawe and Yala, all of which can be visited from the coast as day or overnight excursions.

Weligama is situated on a wide sandy bay about 144 kilometers south of Colombo, between Galle and Mirissa. The sheltered bay is considered one of the best beginner spots for surfing in Sri Lanka, with surf schools lining the central beach.The name means "sandy village". Off the western part of the bay lies the tiny island of Taprobane with a single villa, and on the outskirts of the village is the Kusta Raja Gala relief carved into the rock. West of Weligama, along the coast near Ahangama, Kathaluwa, and Koggala, the famous stilt fishermen sit on their poles.Besides simple surf camps, a variety of cafés and restaurants have established themselves in and around Weligama, ranging from brunch spots to the gourmet offerings of the Cape Weligama resort on the headland to the west.
