The Glacier Canyon in Grindelwald is a natural wonder that took 250 million years to form, offering visitors a unique sensory walk through its rock galleries and tunnels. The canyon features a stunning crystal museum and a 170m² spiderweb for added adventure. With temperatures around 10°C, it's recommended to bring a warm jacket for the 1-2 hour excursion. Night experiences on Fridays light up the walls for an extra magical touch. Don't forget free parking and the option for private tours for groups. It's a must-visit spot for nature lovers and thrill-seekers alike!
