Sprawling tea plantations surround the serene hills of Munnar, which attract adventure travellers hungry for paragliding, treks to Anaimudi (South India's highest peak) and hikes originating at the confluence of three mountain streams. The stone Christ Church, built by the British in 1910, is adorned with renowned works of stained glass, and Eravikulam National Park, about 10 miles away, is home to equally colourful wildlife, including the endangered Nilgiri Tahr (ibex), ruddy mongoose and 120 bird species.

One of Islam’s most holy cities, Medina, is a sprawl of minarets and shops wrapped around the landmark, the Prophet’s Mosque. Like the rest of central Medina, it’s for Muslims only and is surrounded by plenty of hotels and eateries to welcome the pilgrimage crowd.

Singapore is known as a bustling metropolis that also happens to be one of the cleanest and safest cities of its size in the world. (Just make sure you heed the local laws—something like spitting in the street might merely be considered rude in your hometown, but here, it carries a severe penalty.) You'll find historic sites like the Thian Hock Keng temple, superlative shopping (including gargantuan malls) and numerous beaches.

Just three hours from Bangkok, Ko Samet is a favorite weekend beach getaway for expats and locals alike. However, most tourists head further south for their island breaks. Most of the island is protected as part of Khao Laem Ya – Mu Ko Samet National Park, making it clean and relatively unspoiled. The island offers a variety of resorts, from the quiet and family-orientated to those catering to the party-till-dawn crowd.

Bali is a living postcard, an Indonesian paradise that feels like a fantasy. Soak up the sun on a stretch of fine white sand, or commune with the tropical creatures as you dive along coral ridges or the colorful wreck of a WWII war ship. On shore, the lush jungle shelters stone temples and mischievous monkeys. The “artistic capital” of Ubud is the perfect place to see a cultural dance performance, take a batik or silver-smithing workshop, or invigorate your mind and body in a yoga class.

Lijiang is a beautifully preserved ancient Chinese town, infused with cultural flavour. Strolling along the 800-year-old bridges and waterways of the world-famous Old Town district is like stepping back in time. Don’t miss the views atop Jade Dragon Snow Mountain, and the Dongba cultural centre of Jade Water Village.
