Barcelona → Andorra via the C-16 and Cadí Tunnel

Best in
Grand tourer or luxury SUV
Road character
Pyrenean climb with a tolled tunnel and a border crossing
Why
Up the C-16 through Manresa and Berga, the Cadí Tunnel into the Cerdanya, and into Andorra la Vella. Three hours each way through the eastern Pyrenees — and a different country at the top.
The Cadí Tunnel is tolled; the climb beyond Berga can require chains in winter. Andorra customs allowances are strict on the return — keep receipts.
