Lisbon - day 2

Spent most of today at the castle in Lisbon. The sensible way to get there ( it's on top of a hill) would have been to use a tram, taxi, or one of the tuk tuk bicycle taxis that are plentiful. We chose to walk - which was a nice way to see the sights but quite hard work. The walk however was worth the visit - the castle was interesting and a magnificent viewpoint - it was also fairly cheap to get into.
