The holy city of Tirupati draws tourists and religious pilgrims alike, who flock to the Ancient Lord Venkateswara Temple, known for its elaborate Dravidian style and gold-plated cupola. Prayers are offered daily at this popular temple, which sits high in the Tirumala hills. Several other temples dot the town, and the lush countryside contains numerous waterfalls. Tirupati is also home to a rare, naturally-occurring pre-Jurassic stone arch that is 25 feet long and 10 feet high, one of only three of these geological features in the world.

Yekaterinburg is the thinking tourist's city, jam-packed with libraries, theaters and museums, plus seemingly out of place monuments that pay homage to entities like Michael Jackson and a keyboard. The beautiful Yekaterinburg Circus building is an intricate lace dome that arches over seating for 2600 spectators.

Dubai is a destination that mixes modern culture with history, adventure with world-class shopping and entertainment. Catch a show at the Dubai Opera, see downtown from atop the Burj Khalifa and spend an afternoon along Dubai Creek exploring the gold, textile and spice souks. If you’re looking for thrills, you can float above the desert dunes in a hot air balloon, climb aboard a high-speed ride at IMG Worlds of Adventure or skydive over the Palm Jumeirah.

The Blue Mountains are named for the delicate azure haze that lingers along the region, which is actually a fine cloud of oil emitted by eucalyptus trees. The mystical mountains are a labyrinth of plateaus, gorges and gum trees. Check out the Katoomba Scenic Railway (the steepest railway in the world), the Jenolan Caves and the Giant Staircase nature walk.
