I've just spent 3 nights in Anstruther, Scotland before joining a tour later today in Glasgow.
My objective was to see puffins on the Isle of May, a bird sancuary. It was great! The weather was perfect and there were thousands of puffins!
I used this company and did the landing trip:

I can also recommend the place I stayed:

Well run, simple but nice, and the restaurant is good. I ate all 3 dinners there.
Anstruther was easy to reach by Stagecoach buses, there is a stop just a few steps from the hotel.

All in all, this was a very sucessful side trip, A great way to see puffins.
