Hi,I am doing a two week tour of Sri Lanka and want to extend it by a few days to spend some time chilling on the beach at Negombo. I'm thinking of staying at Browns beach hotel. Looking at photos in the web, the beach looks nice but the water/sea looks a bit grey and dirty. I went to Thailand last year and the water was lovely, b lue and clear. Is it comparable in Negombo? What is the water like?
