This is Caño Cristales, a river flowing through an ancient tableland in a remote roadless region deep in the forests of Colombia. Known as The Liquid Rainbow, geologists consider it the world’s most beautiful river.

The colors are due to endemic riverweeds that grow only here, clinging to the rocks of the riverbed, and the crystal clarity of the water. It is not easy to get to – fly a light plane to an airstrip, take a boat upriver for miles, then walk a few miles more. But then you get to explore one of the most beautiful sights nature has to offer – replete with dozens of small fun waterfalls, surrounded by an uninhabited forest teeming with tropical birds.

No wonder National Geographic calls Caño Cristales “the River of the Garden of Eden.” Yet it is only one of the many extraordinary experiences in this huge country – for Colombia is larger than Texas and California combined. (Glimpses of Our Breathtaking World #22 photo ©Jack Wheeler)

The Igreja de São Francisco (Church of St. Francisco) was built 800 years ago on a ledge overlooking the Douro River in Porto, Portugal.  500 years later in the early 1700s, the people of Porto devoted themselves to making its interior supremely magnificent.

Most breathtaking is the polychrome wood carving depicting The Tree of Jesse springing from the reclining body of Jesse of Bethlehem, the father of King David, and showing the genealogy of Jesus through the branches of the tree that are the Twelve Kings of Judah, ending with Joseph and above him the Virgin and Child. Above the Tree to the ceiling is intricately carved woodwork deeply covered with hundreds of pounds of gold leaf.

This masterpiece of baroque art is an awesome tribute to the importance of Christianity to Western Civilization. (Glimpses of Our Breathtaking World #234 photo ©Jack Wheeler)

Dar al-Hajar, the Rock Palace, was built by Yemen’s ruler, Imam Yahya Muhammad Hamiddin (1869-1948), atop a rock pinnacle as his summer residence. It lies in a valley about 10 miles outside Yemen’s capital of Sana’a. While an iconic example of Yemeni architecture, it’s impossible to visit now with civil war raging in the country. Someday we’ll be able to safely return to Yemen again. (Glimpses of Our Breathtaking World #143 Photo ©Jack Wheeler)

This is the wooden Russian Orthodox Church in Karakol, Kyrgyzstan. It was built in the 1890s when Karakol was a garrison town in the furthermost reaches of the Russian Imperial Empire with China just on the other side of Tien Shan Mountains.

In the atheist/communist Soviet Union it was used variously as a school, gymnasium, and warehouse, anything but a church. After Kyrgyzstan gained its independence with the collapse of the Soviet Union, it was lovingly restored by the people of Karakol.

All the various ethnicities comprising Karakol are welcome here – Christian Russians and Christian Kyrgyz, Uighur Moslem refugees escaping Chicom China, ethnic Han Chinese Moslems called Dungans escaping for the same reason, Buddhist and pagan Kazakhs. The interior is lavishly decorated with Christian art and paintings of Christian saints – no Islamic or Buddhist or any other religious art, just Christian. Yet all are welcome to pray in this haven of refuge and peace in their own way.

This is a Russian Church very distinct from those controlled by Moscow run by the Kremlin as a propaganda arm of the KGB/FSB. It is a real Russian Christian Church instead. Come here to feel to the spiritual serenity for yourself. (Glimpses of Our Breathtaking World #221 photo ©Jack Wheeler)

Built as the summer residence of the Portuguese Royal family almost 200 years ago, Pena Palace stands atop the pinnacle of the Sintra mountains with stunning views of the Atlantic Ocean far below.

Today a museum showpiece and World Heritage Site, it is one of the most spectacular castles in all Europe. (Glimpses of Our Breathtaking World #231 photo ©Jack Wheeler)

The Tibetan Monastery or “Gompa” of Spituk overlooks the Upper Indus as it flows out of Chinese Tibet and towards Baltistan in Pakistan. The Indus here is the geological dividing line between the ancient Karakorum mountains and the younger Himalayas (40+ million years old and growing: Mount Everest rises 2 inches every ten years).

We’re in Indian Tibet here, a region called Ladakh where Tibetan culture flourishes freely. Wheeler Expeditions first explored Indian Tibet – including running the remote Zanskar River tributary of the Upper Indus, one the world’s most thrilling whitewater experiences – in 1992.
