Day twenty-four and we jumped out of bed early with the intention of a quick breakfast and pack-up to make the most of a perfectly clear day.

First item on the itinerary for the day was to make our way to the 'Top of Europe' - the Jungfraujoch. It's a bit pricey but with the Swiss Pass saving and the stunning day we decided it was worth a shot.

The first part of the ride to Grindelwald would have been lovely except for a rude woman who shut my window and took up half the cabin. If I had a portable rotisserie on me we could have enjoyed some very juicy pork chops!

The train ride up, including from Grindelwald to Kleine Scheidegg, is a masterpiece in engineering. The views are equally spectacular and larger Alps continue to just rise up from nowhere as you go over each peak.

I would love to see Kleine Scheidegg during the winter. It looks like it has some amazing slopes to Ski and the town, even in the summer, has a great feel to it. Sal fell in love with a massive mountain dog who was keeping all the Japanese tourists happy by posing in their photos.

The train ride from Kleine Scheidegg to the Jungfraujoch is ridiculously steep. It offers two breathtaking view points on the way up that show the valley and the beginning of the glacier. Most of the ride is in a tunnel through rock which took over 15 years to construct.

At the top, some 3454m above sea level, there is a base with a range of activities on offer from different viewpoints to a range of snow sports.

We opted to go straight up to the Sphinx observation deck before the clouds had any chance of setting in. The views were out of this world! And to top it off the military did a fly by in a jet which took Sallie's breath away.

After spending quite a bit of time soaking up the view, we set off on a walk across the glacier. The effect of the altitude was bizarre and we both felt the pinch about halfway up a bit of a climb. There were a few people skiing which made us somewhat envious.

Forty-five minutes after setting off on our walk we made it to the Monchsjoch Hut. The rewarding view was well worth the effort and despite the weather dial reading -3, it felt surprisingly warm. The hut was the best place to be as we weren't surrounded by tourists and there was no noise, so we could really soak up the rare atmosphere.

We enjoyed a super expensive chocolate bar and drink (17 CHF) and then made our way back to the base.

On the way back a few people were walking their dogs. A giant black flat coated retriever was having a ball bounding and rolling in the snow. Sallie also enjoyed watching a number of people on a massive flying fox and a few others tubing.

Once back at base we took in the Plateau which offered some more views and the cute little ice-caves. They had the squirrel creature from 'Ice Age' which I had fun posing with.

Once we had finished in the caves it was time to head back to Interlaken, collect our stuff and move onto Luzern.

We stopped in at Migros (supermarket) and collected some basics for lunch and then said 'goodbye' to our hosts at the B&B.

The train ride to Luzern was another visual feast, with countless lakes and waterfalls keeping us from sleeping.

Arriving in Luzern we quickly found our hotel, Etap, thanks to the trusty iPhone again. This was the first of our no frills hotels. The shower and toilet are all in the cupboard and the compact design of the room is quite clever, if only a little tight. (My massive shoulders did get wedged a few times when moving in the shower.)

We picked up a pizza and a few beers and went for a short stroll down to the waterfront to enjoy it. On the way Sal found the interactions of a few prostitutes amusing and a guy being pulled over by police with one on board. There was no 'Pretty Woman' walking down these streets.

After finishing our peaceful walk we headed back and prepared to cover two cities in one day.
