Driving from Toulouse airport.
From the airport initially follow signs for Toulouse. Once on the city ring road follow signs for Tarbes, this will take you on to the A64 heading towards the Atlantic coast. There is a toll of €2 (cash or French carte bleue only). Leave the A64 at junction 20 heading to St. Girons. At St. Girons take the last exit on the roundabout towards Castillon en Couserans. At Castillion continue straight onto Sentein. In Sentein turn right onto the church square. The Frog and Peach is in front of you at the back of the square.
An SNCF sleeper train leaves Paris late evening direct to Pamiers arriving the following morning. Pamiers is the closest town with vehicle hire facilities
