The rest of the day was spent eating, walking and getting lost.
We ate a good lunch going to a local food court and staying native and then we walked about five kilometers to walk off lunch.
After that we managed to get lost while attempting to recognize landmarks in the dark from a zooming bajaj (tuktuk). It was somewhat inevitable.
In the end we made it back although it was touch and go for about half an hour and the driver made his monthly salary from our detour. Still it cost us about £5 so not the end of the world.
After that we felt we were settling in to Sri Lanka quite well!
