We found the other bus stop in La Hoya, Julie! It is diagonally opposite the one coming in from Yaiza direction (but a very long diagonal) in the direction of Yaiza, set back on an old road. It’s a rather beautiful building made of the lovely dark stones & which looks such a natural part of the landscape that we kept missing it. Got the bus back to Yaiza from there after walking from Playa Blanca so another mystery solved!
