The US is one of only 17 megadiverse countries on the planet, home to vast green spaces, wetlands and forest ecosystems that are protected as National Parks and public lands. In and around them, nearly 3,000 native animal species thrive, including 400-plus types of mammals, 800 species of birds, more than 500 reptiles and amphibians and over 1,100 fish – not to mention 10,000 insects. While opportunities abound for observing the very best nature has to offer, the key is knowing where and when to look – and how to safely enjoy these encounters. Idaho-based wildlife expert Sylvia Medina, author of the Environmental Heroes book series, cautions that you should maintain a distance of at least 25 yards from most wildlife and 100 yards from bears. Don’t feed them, and don’t leave behind any trash they might accidentally ingest. Medina also notes, 'You’re a guest in their home. Keep quiet, and don’t slam doors, shout to get attention, or intrude on their space.' But if you're interested in witnessing these amazing animal phenomena for yourelf, then here are the top places in the US to see the very best that Mother Nature has to offer.
