I'll report fully on Tea Trails in a short while. in Galle we're not at Amangalla but will be having dinner there tomorrow night.
Briefly, we stayed four nights at Summerville bungalow and could have stayed longer, possibly at another bungalow. We looked at the newest, Dunkeld, and Castlereagh. We are glad we stayed at Summerville because we think it has the best view.
We too took the Cinnamon Air shuttle to Koggala. About 60 minutes max from door to door.
