Marta My friend and I rented bikes. It was easy. I booked online and we collected the bikes and helmets from the shop after a late breakfast. The bike shop is only open in the summer - I guess they don't get many customers in the winter. There's a beautiful lake to cycle round with great views of the mountains, but I got pretty tired and hungry. You can return the bike any time you need, so l went back at 2.30 and had lunch.
