Eagles Nest was one of Hitler’s retreats in the German hills. To get there you must drive up a 25% incline road (completely RV unfriendly) for a good 10 Km. You must park in one of the two pay parking lots and proceed to the designated buses. The red buses drive you farther up the mountain to an abandoned shack seldom visited by Hitler and his entourage. Only after paying for 3 hours of parking did we find out that the bus costs a whopping 15 euros per person to go up. We settled on taking pictures from the parking lot area.
