Have you hiked slot canyons before? The Narrows is a good starter canyon. They call it the Narrow because at its deepest, itβs ~1500 feet deep and 22β wide. It's a fun overnighter, 16 miles total, but you are walking in the water and over boulders a lot. Timing is the issue. Monsoon season is late June to August and you get clearance ~24 hours in advance. In June, the water flow may be too high. I would recommend renting canyoneering shoes as the submerged boulders can be like walking on top of alga covered bowling balls. Zion Outdoor Adventure is a pretty cool place to rent gear. If you want to do some really wild stuff, got to Zion Outdoor Adventure and book a guided trip to hike Subway. There is a 70 foot repel there. There are many other guided canyoneering day trips where you may need dry suits and climbing gear. Have fun – Jon
