Tower Bridge, London

Never crowded, and worth taking the time to fully absorb the pleasure of going up the steps (a modern lift is also available) and peering out through the windows at the ever smaller people, buses, and boats passing beneath. Then one reaches the top... You can see so much of town from there, and even get a sticker if you successfully traverse the glass floor! For the children, and some adults, there's a booklet one can stamp as one explores the structure. Once you return back to the deck, you can then follow the line to the south bank, and have a look at the old workings, and of course, the compulsory shop. Definitely a part of a great day out.

This was really unexpected. We thought rather than just walk over we'd try the visit, as the high walks sounded intriguing. Very impressed. There is a nice balance of history and views, and the staff are fantastic. The glass floor is a novelty that provides unique views of the road and river below. The engine room highlights just what a magnificent piece of engineering this is. Well worth a visit.
