Experience of walking part of the Xiamen Mountain-Sea Health Trail

Indeed, the scenery is quite good. I climbed it around 6 PM in the evening, enjoying the breeze, which was quite comfortable. However, the total length is a bit long, 23 kilometers in total. So if you plan to go in the evening, you might only be able to walk part of it like I did. But it might be a bit hot during the day, so my suggestion is to start in the cool morning, then find a place to avoid the heat at noon, and continue in the evening. I don't know if it's possible to finish it in one day as I haven't tried, but you can give it a try.
