We may all be temporarily grounded, but thanks to the miracles of the internet, we can tour this big beautiful world from pretty much anywhere -- with the added bonus of not having to deal with lines and fellow tourists. Virtual tours can take you pretty much anywhere, from distant lands to historic museums to your local zoo. Through them, you can witness eye-popping natural phenomena, explore mountain tops and deep caverns, and tour cities you've always dreamed of visiting. And you can do all of this from the couch. Here are some virtual travel experiences you can do right now.
