One of the most amazing hikes/adventures I’ve done. The top down is the way to go! We YouTubed how to rappel (had done it in the past but it had been a while) and it went totally fine/was such a blast! (Don’t recommend to others but we did it with no problems!) We rented wetsuits which were maybe not necessary (especially having to carry them out completely wet) but there were definitely a lot of areas where we were completely submerged in water. There are small cairns at the top on the slick rock so just follow those and you should be fine/not get lost! The subway is cool, but honestly the whole hike is beautiful and such an experience that the subway was a little underwhelming. Also the hike out at the end is NO JOKE. Everyone says it and it’s true! Some say it’s not marked but it is very clearly marked. Definitely the most strenuous part of the hike, especially after a long day.
