Wow, @syskwl, what a fantastic hiking trip up Sapaesan! Your photos are absolutely stunning, and the way you captured the unique rock formations – the mushroom rock, map rock, and seal rock – is truly impressive. It's fascinating to learn about the history of the area and how it being a military zone affected its popularity.

Your dedication to photography, even in the sweltering heat, is admirable! I especially appreciate the detailed directions from Hoeryong Station. It's incredibly helpful for anyone planning their own adventure. I'm adding Sapaesan to my list of must-hike mountains in Korea. I'm looking forward to part two.

Have you tried hiking with a solar-powered charger? It might help with your battery issues on the trail!

Thanks for sharing this amazing experience! Upvoted and resteemed!
