Back when the dinosaurs walked the Earth, the Valley of Fire was forming. Time and the elements carved the fossilized sand into greats mazes of canyons, arches, ridges, domes, and valleys. Today, the Valley of Fire is a National Natural Landmark and the oldest state park in Nevada. This amazing and colorful wilderness in the Mojave Desert is only about an hour away from the bright city lights of Las Vegas; it comes highly recommended to experience. Sunlight striking the bright red rocks make the valley look like it’s on fire, but there are also layers of multicolored rocks in a “rainbow” of colors that stretch for many miles. Rainbow Vista is a breathtaking site to behold in the Valley of Fire. [38 Photos]

When you think about the Incas, does Machu Picchu come to mind? While that might be where your destination starts or ends in Peru, there is so much more to see in the Sacred Valley of the Incas, or El Valle Sagrado de los Incas. Look up along the Urubamba River and Valley to see Andes Mountain peaks stretching to a height of 20,000 feet. It is over these steep hillsides that the Incas managed to move massive stones without the help of the wheel. They had no iron tools to cut the stones, but still the pieces fit together so tightly that not even a knife blade can slide between them. The “how’s” are part of the secrets to which we might never know the answers. Huge circular terraces at Moray were thought to be where Incas conducted experimental agriculture. Carved into the mountains are also thousands of small salt ponds, Salineras de Maras, or Inca salt pans. All of this is located in the Peruvian Andes, with Cusco on one end and Machu Picchu on the other; this is the heartland of the Inca Empire. This is the Sacred Valley of the Incas. [42 PICS]

We’ve looked at Ireland Now and Then (100 years ago), but to celebrate this St. Patrick’s Day, here’s a look the six national parks of the Republic of Ireland. Killarney National Park was first, and Ballycroy was the last to be established. The Burren National Park is the smallest and Wicklow Mountains National Park is the largest in Ireland. There are also Connemara and Glenveagh as well as landscapes with castles, karst, cliffs, waterfalls and green mossy forests. [38 Photos]

At the heart of Picos de Europa National Park in northern Spain, an adventure awaits hikers. The trail consists of 9 miles along the Cares River and the Cares Gorge, aka “divine gorge.” Steep cliffs stretch up over 6,500 ft (2,000 m) on one side and the Cares River is as far as 650 feet (200 m) below in the deep gorge. The Cares Gorge trail is extremely popular because it is considered one of the most beautiful walks in all of Spain. The footpath was improved about 60 years ago when tunnels were carved into the mountain to serve as a maintenance trail to a hydroelectric power station. Long ago, some sections of the path were used by shepherds, sheep and even goats; the route provided the only communication between 2 villages when it was snowy. The national park was also named a biosphere reserve by UNESCO. If you visit Spain, you might want to reserve a day to trek this beautiful trail. [38 Photos]

If you’ve just been through the mother of all winters, then hang in there. Eventually, all the long hard winters give way to spring. We’ve looked at Europe, where gorgeous bluebells carpet the woods, but winter in Japan gives way to a cheerful springtime bonanza of cherry blossoms. There are also pathways among millions upon millions of exquisite blooms, wonderful hanging wisteria and wisteria tunnels that are like something out of a dream. We hope you like these photos of springtime in Japan. [34 Photos]

The Swallow’s Nest castle high on the cliff above the beautiful Black Sea has become an icon for Crimea, Ukraine. But the Crimea you hear about now involves the Ukraine crisis. While we hope for a peaceful resolution, Crimea lawmakers voted in favor of leaving Ukraine for Russia, as Russia already has the Black Sea peninsula under its control. In 10 days, citizens of Crimea must choose: Stay in Ukraine or join Russia. The crisis in Ukraine made us remember Gagra, the resort paradise turned to ruins, aka the abandoned Russian Riviera. We became curious about what else does Crimea look like, besides a castle? Here are some of what we found; here are amazing natural wonders in Crimea, gorgeous landscapes and seascapes, places with so many caves that they are known as cave towns, as well an ancient ruins that go back to medieval times.
