A lot of walking but well worth the day. Explore the Biosphere where a research team spent 2 years sealed inside. Now open to the public with lots of environmental and plant research still going on today.

I first visited the place just after it opened in 1991. I haven't been back until visiting friends wanted to see the site. We were guided around the remaining biomes and were shown how the structure operates. This is an amazing piece of history. We...More

I have been to Biosphere2 three times and have never seen the abandoned home of a woman who married royalty. We are going again in three weeks and would like to know where to look from - perhaps - the stone patio near the cafe.
