We used East Zion Experiences (https://www.eastzionexperiences.com/
) ... the non-rappelling, UTV slot canyon tour (Note: Crazy ride and it's dusty ... ). There is also East Zion Adventures which has similar tours: https://www.eastzionadventures.com/
Also, for anyone wanting to go into Zion, you must obtain a shuttle ticket if you want to get into the Valley. Details are here: https://www.nps.gov/zion/planyourvis...le-tickets.htm
. There are usually walk-up tickets but they go fast and they won't let you board the shuttle until 2:00 pm with those tickets.
Note: If you want a low-key campground (no frills) that's close to Zion and Bryce, try the Mt Carmel Motel & RV Park. The Bryce-Zion Campground looked nice as well.
