Not everyone wants to hire a car and although the bus service to Las Alpujarras is strictly limited, Capileira is one of the few small villages in Andalucia with a regular service from Granada every day of the week.
There are just three buses a day (including Sundays) and here are the latest times. You can book online with www.alsa.es, buy a ticket at Granada bus station, or pay on the bus itself.
