This morning, I had a very good workout climbing up Mt. Acha in
Seoul, Korea. It is a small mountain and there are nice hiking trails.
An ancient fortress wall from over 1700 years ago on the way to the top.
Some parts are very well kept. Here is a part with many steps.
Finally at the top of the mountain (287 m)! A rock monument stands.
Looking down to the city of Seoul - close from the top of the mountain. There were many hikers - even at around 7:30 AM of Sunday.
