One of the main bus stations in Las Palmas de Gran Canaria, Santa Catalina (the bus station close to Las Canteras) will be closed for the next two months for renovation. This means you can’t take the bus from the normal bus stop untill approximately mid June (though it’s expected the renovation will take longer).
The temporary bus stops are moved a bit north of the Santa Catalina bus station, at the parking of the aquarium Poema Del Mar, around 5 minutes walk. If you’re taking the bus for the first time from this new location, I recommend to take 10 minutes extra into account, just to make sure you will find your bus in time.
The official announcement can be found here.
And here’s a visual overview of where you can find the temporary bus stop per bus.
