Be at the Boya Quarry (also called “Mountain Quarry”) carpark at about 1.30pm. We’ll be in and around the quarry for a few hours so if you come a bit later then take a walk up to the quarry from the car park. It’s only 10mins walk. Too much gear can get heavy uphill though. This google maps link (“Mountain Quarry” carpark in Boya) is centred on the carpark to help you find your way.
I would suggest you have some good footware because some of the steep walks can be slippery with laterite gravel or broken rock.
