Went here 2 years ago with our (then) 12 and 15 year old kids. It was so much more than I expected! It was fun and educational and beautiful! Will definitely go again. Great for all ages, lots of stairs involved, though.

I think you should have no trouble this time of year at the Biosphere II. The weather should be nice and unless they have a special event, you should have no long lines or waits.
