That was a great experience. I hiked with my best friend 18 km / 11.2 miles through the Eifel National Park. We took our water from the river and cleaned it with the #sawyer water filter. The filter is so good that you could drink out of muddy puddles with it. Halfway we cooked ourselves a meal of fried potatoes with bacon and onions. Unfortunately, it is forbidden to light a fire in the national park, so we had to cook with the gas stove. The landscape and many wild animals in the national park are beautiful.
