According to Business Insider website the Greek island of Santorini has one of the amazing vistas worth climbing! From Business Insider:
Corcovado Mountain — Rio de Janeiro, Brazil
Stand next to the famous Christ the Redeemer statue at the peak of Corcovado Mountain. You’ll have a fantastic view of Rio de Janeiro, along with Sugarloaf Mountain to the southeast of the city.Hollywood Hills — California
You can take a trail to the top of Mount Lee to get stunning views of downtown Los Angeles — and, on a clear day, the Pacific Ocean — from behind the Hollywood Sign.Victoria Peak — Hong Kong
Victoria Peak is impressive both night and day. At 1,818 feet, it’s the highest mountain in Hong Kong and offers the perfect view over the busy city. Though there is a tram that can take you to the top, you can also take several different walking routes as well.Preikestolen — Norway
At 2,300 feet above Ringedalsvatnet lake, “Pulpit Rock” offers a great view out over the Preikestolen mountainside. The hike is best enjoyed between April and September.Lion’s Head Mountain — Cape Town, South Africa
You’ll have an incredible view of Cape Town from the 2,200-foot summit, which should take you only an hour or two to reach. Take in the entire city below, as well as Table Bay, located just beyond the coastline.Pikes Peak — Colorado
At a 14,000-foot elevation, Pikes Peak has plenty of hiking to offer. At the top, take in beautiful views of lakes, tree tops, and shorter mountains. Reward yourself for the hike with doughnuts at Pikes Peak Summit House.White Cliffs of Dover — England
Take a stroll along the English hills, which get their white color from the chalk they are composed of. Take in the spectacular view of the coastline, and watch as the waves crash into the stark white cliffs below.Cinque Terre — Italy
After stopping by the town of Vernazza, you’ll want to continue your hike along the Italian coast. Be sure to look back though, as there’s an amazing photo opportunity overlooking the colorful town.Santorini — Greece
To capture this postcard view of Greece, you’ll want to climb up the steep hills and windy roads of Oia in Santorini. This iconic town features small white houses interspersed by splashes of pink, blue and red.Arc de Triomphe — Paris
Take the 284 steps up a spiral staircase inside the famous Parisian Arc. Look out, and you’ll have a fantastic view of the Eiffel Tower and the city of love.Tower of Arnolfo — Florence
Like the Arc in Paris, the Tower of Arnolfo in Florence, Italy, has steps leading to the top — about 400, in fact. Once you make your way up the narrow stairwell (it’s thankfully less popular than some of the city’s other landmarks), look out from the tower for a perfect view of the Duomo and Florence.Seljalandsfoss Waterfall — Þórsmerkurvegur, Iceland
You’ll want to go chasing this waterfall in Iceland. It’s one of the most famous waterfalls in the world and the water drops from about 200 feet. A small foot path carves behind it.Dachstein Stairway — Austria
At the Dachstein Glacier resort in the Alps, you can step onto a 1,300-foot-high, glass-bottomed bridge. This spot is definitely not for those scared of heights.
