There's nothing better than hiking up a mountain and reaching the summit. A hard day's work that’s completely worth it due to the stunning views on top. You can change out of your sweaty shirt, have a bite to eat, sit down for a bit and just enjoy the majesty that is nature. But what comes up, must come down. You still have to hike down the mountain. This can be quite hard on the knees and there are a lot of hikers who struggle with knee injuries because of it.
