- The Periyar Tiger Trail. The programme is unique in being conducted by a team of poachers who turned protectors of the forests.

Normally 20 to 35 km of trekking distance will be covered, depending on the route chosen. Here, one may chance to encounter much indigenous wildlife like Nilgiri langur, giant squirrel, Indian bison, Sambar deer, wild boar, elephants and who knows, even the tiger! The trek route passes through hills and valleys with a variety of tropical plants and wide-open spaces. Enroute vegetarian meals will be prepared and served and simple tents are provided for holing up in the night. Trekking groups are accompanied by armed forest guards with good communication equipments, and geared to face any emergency situation. Remember to listen to unusual and strange adventure stories of the former poachers, now your guides and protectors of the forests. Preconditions for joining the tiger trail: Visitors who are medically fit and aged between 15 - 65 are advised to take the tiger trail. Visitors should be serious nature lovers willing to sacrifice some of the luxuries and comforts of a hotel. WARNING: Beware of certain tour operators for booking a tiger trail especially Mr. Sajimon Salim of Periyar Tiger Trail (http://www.periyartigertrail.in/) who appears to be a professional crook. He goes by various other names, including Saji. He will ask for 100% advance payment at any cost, will not give any receipt, will be rude on asking for confirmation, has been known to cancel the bookings and will not return any money. Instead, your hotel or homestay host will be happy to book in advance for you, or you can reserve through the official website. edit

Periyar is near a pepper-growing region. Try an omlette (or anything you can find) with crushed fresh peppercorns - nothing to beat it!
The best way to experience Periyar is to stay in the treehouse. The ranger will escort you there around 10AM and come to collect you at the same time next day. It is just a wooden box, so bring your own bedding, candles, food etc. The treehouse is situated at the end of a tongue of grassy land with forest on either side. As the sun sets the animals all come out to graze (not the tigers though), and in the morning they are there again as the mist lifts. In between you can kick back, admire the view, listen to the orchestra of insects and birds, and amuse yourself with the grafitti collection.
