The devotees are expected to follow a Vratham (41-day fasting) prior to the pilgrimage. This begins with wearing of a special Mala (a Garland made of Rudraksha or Tulasi beads). In general from then they are to refrain from non-vegetarian food of any kind (except dairy) alcohol, and tobacco, engaging in sex, using foul language, hair-cut, shaving and even trimming the nails. They are expected to bath twice in a day and visit the local temples regularly and only wear plain black or blue colored traditional clothing. Saffron colored dresses are worn by Sanysis (monks) who have renunciated material life. But, many devotees still continue to wear saffron colored clothes which becomes a part of vedic culture which connects the whole Hindus worldwide.
Hundreds of devotees still follow the traditional mountainous forest path (approximately 61 km) from Erumely,12.8 km from Vandiperiyar and 8 km from Chalakayam, believed to be taken by Ayyappa himself. The Erumely route starts from Erumely to Aludha river, then crosses the Aludha mountain to reach Karivilam thodu. Now comes the sacred Karimala crossing, from there to Cheriyanavattom, Valliyanavattom and finally Pamba River. Then they have to climb neelimala and enter into the ganesh bettam, shreerama betta padam. Then comes the Aranmula kottaram, which is one of the halt place of holy journey 'thiruvabharana ghoshayatra'.
These days people use vehicles to reach the Pamba River by an alternate road. From Pamba, all the pilgrims begin trekking the steep mountain path of Neeli Mala till Sabarimala. This route is now highly developed, with emergency shops and medical aid by the sides, and supporting aid is provided to the pilgrims while climbing the steep slope, which used to be a mere trail through dense jungle. The elderly pilgrims are lifted by men on bamboo chairs till the top, on being paid.
