The one euro bus is unbelivable value and a great stress free way to get around the area around perpignan.

Made sense to leave the car in Ceret and use the one euro bus to have a stress free day trip to perpignan..

One euro each way and buses every hour or two. 

Plenty of local buses seem to run from the bus station to the old centre tho a taxi for 7 euro keeps things stress free.
