Grand Prismatic Spring, Yellowstone National Park, Wyoming
Ditch the tourist crowds at Old Faithful and head to Yellowstone's secret star, the Grand Prismatic Spring. Approximately 370 feet wide and 121 feet deep, Grand Prismatic is the largest hot spring in the park and the third largest in the world. The water may look tempting, but don't dive in—it's around a scalding 160 degrees. The stunning colors are caused by different species of pigmented bacteria, photosynthesis, and refracted light.
Newgrange (Photo: Pecold/Shutterstock)
Despite the name, Newgrange is actually older than Stonehenge. The passage tomb (and ancient spiritual place) is most popular during the winter solstice. Every year around December 19 to 23, the rising sun aligns with a hole in Newgrange's roof, and as the rays shine through, the whole chamber lights up. The sight is so amazing that thousands of people enter a lottery to visit during this annual event, but only 20 people are allowed to attend each day of the solstice. Unfortunately for lottery winners, the famous overcast Irish weather means there's no guarantee the sun-dependent phenomenon will take place.
Ngorongoro Crater, Tanzania
Nicknamed "Africa's Garden of Eden," this volcanic crater houses about 25,000 wild animals, as well as an incredibly diverse sub-Saharan ecosystem—meaning visitors can see everything from open plains to alkaline lakes in one spot. The crater serves as a natural zoo, holding the "big five" (rhinos, lions, leopards, elephants, and buffalo) all in one place. Visit in December or June during the annual migration of wildebeest and zebra, when over 1 million of the creatures enter and exit the area.
