You will go with a katamaranship from the beach to the reefs of Negombo. There you have the chance to see fancy fishes and corals when you go for snorkel.
You will be excited about the underworld over there. You can also see the wrack of a ship from South Africa.
If you like, you can take a drink there or just relax a little bit in the sun. And maybe you get the chance to watch some dolphins by jumping around.
