From time to time I enjoy taking hikes in the mountains to see a beautiful sunrise and sunset. When doing this, I always guess when the sun will rise that day and then I plan my tour accordingly. But this is not always that easy, especially in the mountains, when other mountains can delay a sunrise dramatically.
So I'm looking for a tool or resource where I can enter the coordinates of the mountain I want to visit and that then calculates the time of sunrise and sunset.
