Ainsa is the terminus of the minibus from Sabiñanigo through Torla, which skirts Ordesa National Park.

If the bus drops you at the bottom of the hill where hte newer part is, you may wonder why you bothered to come - but look across the road and you will see a sign for pedestrians pointing upwards towards the old part and what a transformation.

You have a huge square surrounded by cloistered buildings with the church at the end and two steep parallel lanes leading down from it.
