The coastal areas of Earth’s main landmasses harbor unique environments that are worth exploring, though sometimes it is well worth the effort to trek inland, too. Ranthambore National Park in India is where you will find the tawny Royal Bengal Tiger creeping through the grass as it explores its kingdom. A good portion of the way around the globe from India, Ecuador’s Galapagos Islands contain a variety of reptiles and flora that do not exist outside of this region. Corcovado National Park in Costa Rica offers a backpacking experience of a lifetime through the region’s last stand of old-growth rainforest that dazzles and fascinates with every step. Observe efforts to protect the Giant Panda at the Wolong Nature Reserve in China, and discover the staggering diversity of aquatic life that calls Australia’s Great Barrier Reef home. Your once-in-a-lifetime excursion to the Earth’s must see places concludes at Serengeti National Park, and the Masai Mara National Reserve, where you will witness one of nature’s most awesome spectacles, the annual migration of countless wildebeest, and the crocodiles that eagerly await their crossing at the Mara River.
