Galle Fort
Galle fort was originally built by the Portuguese but it was the dutch who modified it and made it the impressive fort it is today. It was built mainly to control the cinnamon trade but later on it served as a fortress to hold off invasions. Inside the Galle fort you can find few of the most preserved building from the colonial era with the beautiful churches inside the city being the prime examples. You can still see the remains of the old guns , fortifications and the canals dug to make Galle fort and impregnable fortress. One of the favorite things among locals is to go for a stroll in the fort walls during the evening and enjoy an ice cream or something a bit spicier.

Yala National Park
Yala national park is the most famous national park in Sri Lanka and it is definitely the one most visited by the tourists. Watching animals in there natural habitat is one of the main reasons tourists come to Sri Lanka and in that regards Yala is the best because of the wide variety of animals you can see in Yala. Deer , Wild boar , Crocodiles , Peacocks , Buffaloes can be easily spotter. Leopard , Elephant and the bear are a bit hard to spot and it largely depends on the skill of your guide as well.
