For centuries the hub of India’s spice and tea trade, Fort Cochin occupies the northern tip of a peninsula dividing the mouth of the Vembanad Lake from the Arabian Sea. Its low-rise, red-tiled skyline bears the imprint of its former colonial residents: Lusitanian chapels, Jewish synagogues, Dutch burghers’ houses, Armenian mansions, and British bungalows and godowns (warehouses) all survive in the Fort’s grid of narrow lanes – the largest collection of early colonial buildings in Asia.

Visitors can savour the atmosphere of bygone eras by staying in one of the beautiful heritage hotels that have opened around the waterfront. Watch the container ships, oil tankers and local fishing boats chug past the famous Chinese fishing nets over a gin and tonic on your own verandah, then dine on spicy Keralan coastal cuisine in some of South India’s finest restaurants.

Your guided tour of the city’s chief landmarks takes in the beautiful Dutch Palace in Matancherry, famed for its traditional Keralan murals, followed by a visit to the old Synagogue in nearby Jew Town. This district holds several huge, and very well stocked, antiques emporia that are well worth a browse. In the evening, the group will be driven up to Fort Cochin for a sunset cruise around the harbour, where you’ll see the iconic Chinese fishing nets in action, along with a variety of craft, both large and small, from dugout fishing canoes to giant container ships.

The mountains of inland Kerala, which run the entire length of the state, are one of the world’s biodiversity hotspots. Tea, coffee and spice plantations dominate many areas, but abundant forest also survives, and the Periyar Wildlife Sanctuary encompasses one of the most readily accessible of these. Centred on a flooded valley system, the park is among the largest in India, famous first and foremost for its herds of wild elephant, which congregate in the dry season around the shores of Periyar Lake.

Boat safaris on Periyar Lake are fun, but too noisy for serious wildlife spotting. A better option is to take to the footpaths in the company of a local guide, who can track and identify the many creatures who live in this well-preserved tract of forest. Malabar giant squirrels, palm civets and sambar deer are commonly encountered, as are hornbills and other spectacular birds. Elephants may be sighted around the water’s edge and are best viewed from the safety of a boat or safari raft.

Up until the 1980s, large barges made of oiled jackwood and canopies of plaited palm leaves were used throughout the Kuttinad region to transport rice and other produce through the backwaters. Now, trucks do the haulage work, but the boats – known as kettu vallam in Malayali – take visitors on cruises around the canals, rivers and lagoons of this fascinating region, where most of the population still live in island villages.  A far cry from the oily craft of old, kettu vallam are today fitted with comfortable en-suite, air-con bedrooms, galleys, and viewing decks from which you’ll be able to watch the watery world slip past. Four-course meals of delicious Keralan curries are served by liveried staff in the evening.
