Today I went on my third Treasure Trail (I have done Treasure Trail Fitzrovia and Treasure Trail Royal Wedding), and this one was based in Hampstead. It involved a two hour walk around Hampstead (High Street and Heath) finding and answering clues along the way.
The clues may be on buildings, pavemarks, lamp posts, signs etc, so you have to keep your eyes open and glasses on!
We ended with a pub lunch by a roast fire. Bliss.
