Bielsa tunnel
We used this tunnel in June this year. Beautiful Spring day.
No charge for the tunnel, opened in 1970. Looks more like 1870. Very narrow and poor lighting. Although built for two way traffic, it was alternate one way when we were there.
On this day we travelled from lak Caspe to Altea.260 miles too far for us and our 26 year old Talbot.
Spectacular views of rivers and mountains. Winter travel, think carefully.
The A123/n240 are both excellent. In good weather you can see, in the far distance, wind turbines which you pass later on. Snow poles are evident on these roads for miles, suggesting lots of white stuff later in the year.
Fuel is available at Barbastro didn't see any other.
Follow these roads to Lleida.
