The longest in the Dante's, Paradiso is also one of my favorites. It has enough down climbs and challenges to keep you interested, but is not overly challenging or physical.
The canyon is a mix of narrow slot, interspersed with more open sections. The final slot section and rappels, in particular, are stunning. I would recommend Purgatory as the best introduction to the Dante's, with this canyon being a good second canyon in the area.
Note: The numerous downclimbs and narrow sections make this well suited to intermediates and above. Beginners with a few canyons under there belts may enjoy it with competent leadership, but rank beginners may be a little overwhelmed. Also, the sections are narrow, with one spot in particular that will be difficult for guys in the "deuce plus" club. (200+ pounds.) Bigger guys can climb over, but with quite a bit of difficulty.
