The last segment of my trip was to have a relaxing time by the beaches of Hikkaduwa and visit the historic Dutch fort, Galle. Surprisingly, there were lots of foreigners in Hikkaduwa and the beaches were actually mostly foreigners. The few locals I did see were either working at the hotels or restaurants on those beaches or selling food and drinks. However, this population is fairly diverse so not sure you’ll be meeting people from your own countries.
Our hotel was not on a beachfront, and this was ok. The hotel itself organizes weekend parties that go on till the morning, and its free entry for guests. As for our beach needs, a friend owned a hotel & restaurant nearby (Hotel Blue Note). We would just chill there enjoying the cool breeze from the ocean.
