Climbing:

If you give them climbing opportunities, they will usually use them. Plus it gives them some exercise! Always a plus for an animal that's prone to being overfed in captivity lol.
If you're going for an adult enclosure I'd get one that's around 4 foot length. I think the exo-terras max out at 3 foot, unfortunately. There are PVC enclosures that get even larger than 4 feet, so that might be something worth looking into. They are also amazing with retaining humidity and heat, from other people's accounts.
