When there...
On leaving the Glacier don't forget to visit the Bikers Nest cafe. Nice cobbles to negotiate up and down. With good weather a wonderful view. Buy a T shirt to remember it by.
PS if anybody going this year can remember.. when buying your tickets they give you some stickers... get me a replacement set. I lost mine when a dozy car driver wrecked my panier which had them stuck onto.
Enjoy your trips.
