Low climbing logs are fine, I would not get any that are over a foot tall. Most ball pythons are clumsy climbers, but some can be very good. Also, fake plants that are grass like that they can hide and crawl through would be nice, as they prefer to be hidden and secure.

-I do have to say that I agree with the others about the water fall. They look great, but are really not worth the trouble.

Any how, good luck, and post some pictures when you are done!
