Fun in the sun isn't all about the beach. In southern India you get exotic food, wildlife watching and glorious landscapes, too, says Harriet O'Brien

Turmeric and cardamom and pepper and cinnamon: the combined aromas teased the taste buds and induced a welter of anticipation. Lunch was in the making as we embarked and explored our quarters.

We had boarded a kettuvalam, a traditional-style Keralan rice barge with an all-enveloping mantle of woven bamboo. Since the early 1990s these vessels have become a tourist attraction, adapted and fitted out as small floating hotels with en-suite bathrooms and spacious dining and lounging areas. Ours, a deluxe model, had just the one large bedroom leading up to a sundeck. From on board, the beauty of the area unfolds as the houseboats serenely ply the myriad canals and lagoons that make up the backwaters of India's prettiest southern state. The palm-fringed waterways were constructed to link villages with far-flung rice fields, although you might be forgiven for thinking they were created purely with aesthetics in mind.

Our rice barge sauntered slowly from the fishing town of Alleppey and stopped by a lagoon-side rice field where we finally sampled the lunch that so tantalised us: vegetable curry and prawn masala with lacy rice pancakes. That evening Reji, the chef and chief of the three-man crew, gave us a cookery demonstration, producing fish curry with overtones of tamarind and coconut; avial, a traditional vegetable goulash with grated coconut, snake gourd, turmeric and cumin; and dhal with a subtle kick.

Kerala's dishes reflect the complex combination of cultures (Hindu, Muslim, Christian of numerous persuasions, Jewish) that for centuries have cheerfully co-existed in the region. For example, biriyani came from the Islamic Mughals of the north, while string hoppers (steamed ribbons of rice-flour dough) were introduced by the Portuguese. Most of all, though, the cuisine of Kerala is a celebration of a wealth of natural produce: notably coconut, fish and spices.

The spices, particularly, intrigued. So when our boat trip ended we headed up to plantation country, the source of these pungent flavours. First stop, the rubber estate of Kanam. There an old colonial plantation house, dating from the days of the Raj and aptly named Serenity, is now a sublimely peaceful boutique retreat with yoga master and on-site elephant who takes guests for rides. The retro atmosphere is almost palpable. Every effort has been made to preserve the authentic decor of the 1928 house. The ebullient young staff take enormous pride in their surroundings, enthusiastically recounting the history of the house and showing you the spice and herb garden they have carefully planted with nutmeg, pepper, tulasi (a type of basil), ginger, chilli and more. We dined outdoors on some of the fruits of their labours - spice-infused prawns with piquant salads of green banana and papaya.

Onwards and upwards to the Western Ghats range of mountains. About five hours' drive north of Kanam, the slopes around the little town of Munnar are coated in tea. At an altitude of 5,000ft and more, the area also offers conditions in which many of Kerala's spices thrive. In the midst of the trim tea plantations is a 66-acre cardamom estate on which the owner has lovingly developed a wonderfully comfortable hotel with stunning views. The 15 rooms at the Windermere Estate are in chalet-style buildings gently suffused with the scent of cardamom, which is processed in nearby drying chambers. A new central dining area was being completed when we were there, with a separate kitchen where, due to popular demand, cookery demonstrations take place.

The two-hour plantation tour was pleasantly gentle, but for serious exercise we opted to take a two-day trek in the area. It is a spice-land rich in wildlife, and even before we reached our trek's starting point near the Manupatty Reservoir we passed a quartet of wild elephants feeding in meadows near the roadside. That night, as we camped at a remote edge of the Western Ghats bordering Tamil Nadu, our guide concocted a vegetarian spread of spicy cabbage, piquant beans, cauliflower with coconut, potato with turmeric and more. Magicked in the dark from a tiny kerosene stove, it was an astonishing feast and an unexpectedly glorious mix of Keralan flavours.
