Titlis from Lucerne. The rotating Rotair cabin to the summit, the Ice Flyer chair out over the open glacier, and the cliff walk, the highest suspension bridge in Europe. The glacier cave is bored into the ice; you cross it in a blue half-light with the cold coming off the walls.

The Eiger Express gondola swings up under the north face of the Eiger to the Jungfraujoch in under three quarters of an hour. At the Top of Europe the Aletsch glacier runs away below the Sphinx terrace, and even in summer the snow is deep enough to walk out onto.

We came into Paris by evening and took the vintage tour in an open-top 2CV. The little Citroën rattling past the lit-up Opéra, along the Seine, around the Arc de Triomphe with the driver pointing out the corners. Paris by night from a sixty-year-old car has its own glamour.

The lift to the Eiffel summit floor gives you Paris flat to the horizon, the river threading through it. The Seine cruise after passed back under the tower at dusk just as it began its hourly five minutes of sparkle, the whole structure lit gold and flickering.
