This research facility provided us with an excellent guided tour! The development of this site was a monumental endeavour but the results are spectular. I don’t want to spoil all the features for future visitors but suffice it to say ‘you will not be disappointed’.

Very interesting and educational. Tour guide is essential. Cost is reasonable. Locational is a little out of the way, but worth the drive.

Take the free tour so you'll be able to walk the underground passageways and see all the incredible machinery and massive lungs that maintain proper air pressure in the biosphere. Great photo opportunities, fun, and educational. We had a great visit!

I recall the 2 past missions/experiments and did not know why they failed until this tour. Very interesting tour. Lots of walking and some stairs. Admission $21.00 adult. Senior and military discount. Tours first come basis. Tours last about 75 minutes.
