Hi Rich!
There is great basketball in the Poli Deportivo Paco Cantos.
This is how you get there:
If you come from Elviria and drive through Marbella, almost when you get to the golden mile, you get to the Marbella Congress Center (opposite is the Corte d'Ingles furniture store).
Just before you get there, take the right and go uphill (passing Mac Anthony Real estate office).
Crossthe traffic lights and go straight.
Then take the first small road to the right.
There is a sports ground with basketball, football and tennis.
Every Saturday and Sunday lots of people meet to play 1 on1 but also teams.
It´s an awesome place.
Costs nothing.
Check it out.
