The survey, conducted by online travel portal TripAdvisor, lists the UNESCO Cultural and Natural heritage sites which are best rated by travellers around the globe.
"You can find hundreds of tours and experiences to visit this mesmerizing site, from a private tour with guide and visit at sunset or sunrise, to a visit including a home-cooked meal at a local home in Agra," the travel portal was quoted as saying by news agency PTI.
The Taj Mahal was designated as a UNESCO World Heritage Site in 1983. It is described as "the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage". The monument receives 8 million visitors per year.
Government statistics, however show that every fourth foreign visitor to the country visits the Taj but there has been a decline in the number foreign tourists to the white marble mausoleum, widely considered one of the world's seven wonders.
The best views of Angkor Wat, a temple complex and the largest religious monument in the world, are at dawn or dusk, "when the crowds have gone and the lighting reveals its true majesty," the travel portal said. The places is best toured with a knowledgeable guide, it said.
The other monuments that featured in the notable list are Iguazu National Park in Brazil, Italy's Sassi of Matera, Auschwitz Birkenau and historic Krakow in Poland, the old city of Jerusalem in Israel and the historic areas of Istanbul in Turkey.
