Hi revenueman,
Friends have just visited our house for last 2 weeks of July. They got the Airport Bus to Granada, it drops off at the train station, Gran Via, and the main BUS Station. As it was Sunday they got off at train station and got train to Iznalloz., 4 trains per day in each direction, see Rudina web page for timetable details. Buses also go to Iznalloz from the train station on all days but Sunday, there are more buses, approx 1 per hour at peak times, again see Rudina web for timetable info. The family flew out from Liverpool and got into Granada in plenty of time for a train service about 1.30pm.
