Is there a bus which goes from Cala Bona to Palma giving me enough time to see the cathedral and go on the Soller train i.e. it is a conceivable day trip. If so how much does it cost and does it go frequently? Is it easy to board the Soller train from the centre of Palma and how much does it cost? I have heard that there is an express bus from Cala Bona which is more time effective than the normal bus. Is this so?
