Autumn and I went hiking a couple of weeks ago.
Geumjeong Mountain is a mountain in Busan. It has an old fortress at the top, and a cable car (um...aerial tramway?) to the top. We did not take the cable car and instead hiked to the top. I did not die. We took the cable car down and did not have time to explore the fortress (which is really a big stone wall... we will hike it another day!)
I didn't realize how far we had come until we hopped in the cable car to go back down. That bridge in the upper right is at Gwangalli beach, where I stay every weekend. And see the train track just to the right of the red cable-holder-thingy? We walked FROM THERE. There was no mid-mountain trailhead to which we took a taxi. Oh, no. We did the whole thing.
And then celebrated with milkshakes, like you do.
