Inside Carlsbad caverns in New Mexico
Having just hiked an impressive 800ft up in 1.2 miles. Advertised as a tough 1-1.5 hour hike, I surprised myself at doing it in 20 minutes. I felt exhausted, exhilarated and high afterwards, finally after so many attempts at running I get what they mean by “runner’s high”. It was super steep and it was awesome to be the only one walking (at times running!) up while everyone else was going down and taking the elevators back up.
