Reported that you can safely get to the bus stop for Line 7 Giro bus, outside Leroy Merlin, from Algarve Shopping by walking out the western side of Algarve Shopping (opposite Decathlon), from the lowest car park exit level -1, signed towards Portimao as there is a road underpass which has a footpath alongside, which goes under the main road and when you come up the other side you're right by the bus stop outside Leroy Merlin.

The same applies in reverse if coming from Albufeira on the 7. The stop at Leroy Merlin is after the bridge.
