Day 15: Hike up Sidelhorn

    One of the cheapest altitude training must be sleeping in the car on the Grimpselpass carpark (you need to pay 10CHF  to the hotel, or if you eat at their place sometimes even nothing) ... some years ago I already slept in the Grimpselhotel, but in the car is definitely more quiet.
    As it was a resting day I only planned a small hike tot the Oberaarsee, but I ended up taking an alpine route up to the Sidelhorn.
