Bonus cache for completing the Rhoose point adventure lab! Not that its going to be that easy for you!
Coordinates you'll need are N 51° AB.CDE' W 3° FG.HJK' and some patience probably at final GZ!
Please be aware, during the summer months and warmer weather, Adders (snakes) can be active around this area, so please keep an eye on any children and/or dogs, try to stick to the paths and watch where you are walking. Generally though there should be no issues so have fun!
