Fun

Galle is not a major cultural centre, nor does it offer much nightlife. However, there are plenty of enjoyable things to do in Galle.

Places to go

The Sun House: a boutique hotel that sometimes has events such as cocktail happy hours. Get on their mailing list.
The Amangalla: the oldest hotel in Sri Lanka. It has been beautifully restored. It has talks most months (billed, somewhat pretentiously, "Amangalla Salon"). Another mailing list to be on.
The Lighthouse Hotel. Not much happens there, but it has a lovely terrace with a view, and a moderately good restaurant.
