We brought our science-loving 5 year old here for a tour and he enjoyed it, as did we. Come expecting an educational experience and you won't be disappointed. Yes, it requires attention and focus, and might not be appropriate for young children, however if they are interested in science it will be right up their alley. This place has pioneered... More

Not impressed. I had always wanted to check this place out. Saw a groupon and since it's only a 2 hr drive decided to make a day of it. I'm sure back in the 90's it was awesome but now it's outdated and sad. The displays seemed thrown together. The tour gave very little information. The guide was very nice... More

We have lived in Tucson for over 6 years and have wanted to visit the Biosphere. Had family in and visited this last week. What a complete disappointment. The tour guide was bored, gave a feeble explanation of the rooms we saw. It seemed he had to keep us in each area a set amount of time. He kept looking... More

Interesting afternoon, we came because the place we were intending to visit was closed, so an impromptu trip here turned into a very interesting afternoon. Our guide Lyn was very informative although at times a little difficult to hear. I would advise taking water with you, there is a lot of walking and standing around. My husband particularly found the... More

On the way to the adress our GPS in the car got lost and we had to drive for 45 more minutes before reaching BS2 which is impressive to look at (inside and outside). If you take a tour with children be aware that you can't take your strawler with you. A nice place to visit if you're in the... More

It was such a great place to learn so much about different echo areas from around the world. Rainforest, ocean, desert. The guide was amazing, our grand daughter learned so much, he was very patient about answering her questions. There is a lot of walking, stairs and ramps. I would not go again in the summer as it was so... More

The place is amazing and has beautiful grounds. The guide was informative. I am just a skeptic I guess. I mean when the 8 people lived there and the project was abandoned they say it was because of El Nino inhibiting the plant growth. If it is a self contained biosphere shouldn't that have no bearing on the inside atmosphere.... More

This place is a long way from anywhere and typical admission is $20/person. Although, the ride out is very scenic. There are several displays and informative movies that you can view without paying fee. The mission for this facility has changed from the original sealed structure. It's an ok place but too expensive IMHO.

We enjoyed the tour. The guide was very knowledgeable. My grandson loved seeing the "lungs" and the rainforest. Although there was less open to the tour than when I was there three years ago, that was disappointing.
