Took a visit to Zermatt Switzerland and did a popular and spectacular hike in Zermatt. The 5 lakes hike. Elevation 7500 ft MSL. Fitness and breathing are a big consideration as the elevation takes its toll on your energy and stamina. Weather can change quickly so be equipped. I brought a rain coat and needed it as on the way down thunderstorms started and it got windy and rainy very quickly.
There are some supplies along the entire route, restaurants, water etc. Bring an extra battery for your phone or camera as there is no where to charge anything. And good hiking shoes is a must for the sections that I did. Walking sticks a plus as terrain can be loose and uneven and narrow at points.

I started from Geneva and took the train to Visp and connected to Zermatt. The train system is Switzerland is good and you can get to Zermatt a number of different ways, but not by car. Only trains go into Zermatt.

As usual my go to app for hiking is Maps.me. Download the map for the area before go.
