About the Adventure Lab
The Royal Crescent in Bath is well known as a great example of Georgian architecture, but did you know there are (at least) 7 Georgian Crescents in Bath? This will take you to 5 of them on the northern slopes of the city. I left out Norfolk Crescent and Widcombe Crescent as there can only be 5 stages, and to make the walk more compact. This can be done as a circular walk of about 2 miles.
The stages can be done in any order, but to make it a circular walk and find the bonus I suggest you park near the posted coordinates for the Adventure, N 51 23.571 W 002 22.119. Please take note of the parking signs, some sections are 2 hours free parking, others residents only.
The order I walked it is:
1. Somerset Place
2. Cavendish Crescent
3. Royal Crescent
4. Camden Crescent
5. Lansdown Crescent
The bonus cache is closest to Somerset Place
