Also, wear the appropriate shoes. It’s best to wear hiking or trail running shoes with enough traction to keep you from slipping off rocks. Bonus if your shoes are waterproof!
As for any additional essentials, it’s always a good idea to carry a bottle of water, and to apply sunblock and bug spray before you head out on the trail.
For those with any previous or current leg injuries, not in good health, or have poor balance, I would avoid this hike as you wouldn’t want to further injure yourself. However, if you’re athletic and have a brave heart to take on the challenge, then by all means! Enjoy!
