This ride up to the summit is an incredible, unforgettable experience. I went in April as a family of 4 with kids aged 10 & 8 and we loved it all - especially the Pipe and Step into the Void glass box which was awesome even in the cloud and snow, so doing it on a clear day would be even more amazing. It wasn’t a busy day so we enjoyed no waiting times and plenty of space to look around the different features of the experience - the tunnel and the 360 platforms were a massive highlight. The views are breathtaking and it’s so peaceful to be so high into the mountains. The experience is so well thought out with tonnes of different sections, views and exhibits. We stopped at the Plan d l’Aiguille Terrasse at 2317m the first stop point in the cable car journey on the way up to acclimatise and take in the views at that height before continuing on up and taking the second car up to the Piton Nord summit. My youngest did suffer with the altitude after being at the very top for nearly an hour so it’s worth considering not spending too long up there with kids and to pay attention to how you’re feeling as it can come on suddenly. We ordered croque toasties and a hot dog in the cafeteria which were good, but pricey, so take a picnic up with you if you want to limit the cost of the trip. Overall, given everything you see and how mind blowing it all is to experience in a few hours, the price of the ticket is more than worth it. The journey back down is just as much of a thrill as you look back up to the summit and question whether you were really all the way up there in the clouds - my favourite part on the way up and back were the three sections in the cabling where the car passed through a joining bit and did an unexpected bump and tipped a bit before speeding up an whooshing faster and everyone when woahhh in unison. The whole day was an unforgettable rush!
