Bonus for Farmoor Adventure Lab - final coordinates available by visiting the Adventure Lab stages. You need to answer a second question at each adlab stage to get the final coordinates.
Do not visit the icon coordinates unless you have a dinghy.
Field note - when we placed the bonus and researched the Adventure Lab stages in November 2023, 2 of them were inaccessible due to flood water on paths / tracks about 10cm deep. Do not take any risks. Wear wellies - or go at a time of year when you are sure the Thames is not flooding. As we go birdwatching every couple of months here, we will post updates on any flooding (17/1/24: paths are fine, bit muddy by Thames).
We do hope you enjoy the walk and the wildlife - the adventure lab is designed to help you do that, and the bonus is very straightforward. If you are keen on birdwatching, then try our puzzle cache GCA9Y93 . It would be great to read in logs about any birds you see on your walk.
