The Taj Mahal is obviously a must-see tourist attraction, but what other historical sites should visitors not overlook?

Delhi's Qutb Minar complex is one of the most interesting historical sites in town and contains centuries' worth of structures, some dating back to as early as the fourth century. In Jaipur, don't miss the City Palace, the home of the city's royal family and an interesting mix of Mughal, Rajasthani, and European architectural elements. Pushkar's Brahma Temple is another must-see, and is one of the only temples dedicated to the creator god in the world.

Do you recommend visiting India by train? Any tips for train travel?

I think the train is the best way to see India, and Delhi, Jaipur, and Agra are well-connected by rail. If you’re traveling by train, bring plenty of drinking water, as it’s not always readily available onboard. Hand sanitizer and toilet paper are also a must. Note that the air-conditioned carriages can get very cold, so it’s a good idea to bring a shawl or sweatshirt with you.

What are the differences between Delhi and Jaipur?

Delhi is a lot bigger than Jaipur and is essentially a conglomeration of neighborhoods and villages that have merged together over the centuries. Delhi is also a bit of a pan-Indian melting pot, and its residents hail from across the country. Jaipur is a planned city and is a bit easier to get around, with more continuation between neighborhoods. In terms of accommodations, Jaipur definitely has more traditional digs, and if you get a chance, try to stay in a converted haveli (townhouse) hotel.

Why do you think Angkor Wat should be on someone’s “bucket” list?

The ruins of Angkor Wat are surely amongst the most breathtaking buildings ever erected. From here, a thousand years ago, one of the world’s great empires ruled large portions of Southeast Asia, fought wars, and built temples—hundreds of temples, some of them so large it took 80,000 people to keep just one in running order. Eventually abandoned by the vagaries of history, the temple ruins have been back on the tourist map for the past decade. Despite the crowds the temples now attract, Angkor remains a show-stopping experience. Surrounded by jungle, the ancient Khmer monuments—exquisite and bombastic in turn—are magnificent architectural marvels rivaling any old structure in Europe. However, it is the interplay between nature and stone that gives Angkor its “Lost City” ambience, its sublime beauty. Visit in the rainy season and you will have corners of some of the ruins all to yourself.

Is there a place you’ve dreamed of visiting, but have yet to get there?

As a travel writer, I have been to countless beautiful places around Asia and the Middle East in the past 15 years. The problem with working in amazing places is that there’s little opportunity, time, or leisure to soak up the ambience. One passes through without really taking in what casual visitors are able to soak up. So there are quite a few places I have been to but never truly visited. I visited Ladakh in northwest India some years ago, but I never got the chance to visit Panong Lake, which lies partly in Ladakh and partly in neighboring Tibet. This stunning, high altitude lake can only be reached in the summer; one needs a special Inner Line Permit, as it straddles the sensitive Indian-Chinese border. I hope to make the journey one day, late in the season, just before the arrival of winter.

The Call of the Wild in Northern India

The Golden Triangle is home to some of India’s most spectacular national parks, some of which are also home to wild tigers. If you’re more interested in Mother Nature than in monuments, Northern India won’t disappoint.

Encountering the Khmer Smile in Angkor Wat

Tom Vater believes a “trip of a lifetime” need not be a trip to the end of the world, but it does perhaps need to be a trip that will linger in the memory long after one has returned home. For him, the very first time he visited Angkor Wat was such a trip, and he shares the moment that made him fall in love with Cambodia.

Agra, Delhi, and Jaipur: Like Nowhere Else on Earth

The North Indian cities of Delhi, Jaipur, and Agra (home of the Taj Mahal) are collectively known as India’s Golden Triangle. Even a brief visit to this region will give you a good feel for the country’s regal past, not to mention plenty of amazing memories of your own.
