Unawatuna is a great town off the southern coast about 2.5 hours from where I live. It’s chill enough to not be FULL of tourist (like Hikkduwa which is essentially the Sri Lankan Santa Cruz) but not too mellow to the point where there is nothing to do like in Mirissa.
Unawatuna offers great accommodations, great water to swim in, great food and great nightlife
in short it has great brownies, beaches and dancing. it’s simply the best ( as Tina Turner would say)
