(via Jaizkibel 455m, Pasai, San Sebastian, Igeldo 400m Zarautz & Getaria)
Cycle out of Hondaribbia on the GI-3440 up to Na Sa de Guadalupe - hard going 4km climb with church and views across to Baia Txingudi and the French/Spanish border. Then another 7km climb to Alto de Jaizkibel (says 445m on the map, but signs say 455m).
Freewheel down at 35-40mph but watch out for sudden multiple hairpins!!!
Turn right at the bottom into Pasai, beautiful ancient port town. A ramp near the end of the road takes you to a small ferry crossing- 20 or so people at a time, and maybe 2 bikes. 0.60€ per person and bikes count as another person! The ferry takes you over the port to Pasai S. Pedro and an easy cycle into San Sebastian (6km).
Lunch in one of the beach bars in overlooking the Gros beach surfers, before the city- it gets more expensive the other side (la Concha)
'People' bar at San sebastian.
Bocadillos de calamares & beer €9.20 each.
Then follow the coast road through town - mainly cycle paths - round la concha (it goes on to El Peine de Los vientos) On the outskirts heading west look for signs to Monte Igeldo.
At the start of the hill, you'll find Camino hostel 25 via Igeldo to stamp Pilgrim pass.
Then begin to climb. About 6km of hard uphill is followed by 10km freewheel down to Orio, and then pick up the N-634 coast road to Zarautz and then on to Getaria and to Zumaia along more epic coastline.
There's an odd bit before Zarautz where we followed the coast road to a dead end and port building but the turn off (unsigned) is pretty straightforward as the only left turn before it. Unfortunately this is a narrow, steep and concrete surfaced road. Not fun.
Finally up a killer hill to the hostel overlooking Zumaia €18/night
