ReadThe trek
A long forest walk, a granite cone and a rope section
Agasthyarkoodam sits inside the Agasthyamala Biosphere Reserve in Thiruvananthapuram district. The route starts at Bonacaud, climbs through forest and grassland to the Forest Department camp at Athirumala, and finishes on a steep rock face with safety ropes before the summit where a statue of Sage Agastya stands.
It is a hard trek. The days are long, the climbs are steep and the forest is a protected area with firm rules. If you prepare well and go with an organised group, it is also one of the most rewarding walks in the Western Ghats.

Quick answers
Before you decide
How hard is the Agasthyarkoodam trek?
It is widely regarded as the toughest trekking route in Kerala. Expect 50+ km over three days, steep ascents and a fixed-rope rock section near the top. Good stamina matters more than speed. Read how to prepare.
Do I need a permit?
Yes. Entry is controlled by the Kerala Forest Department and tickets can be booked only by a registered applicant on the official portal. See how permits work.
Can women trek to Agasthyarkoodam?
Yes. Women have been able to trek since the 2019 season, following a Kerala High Court order. Women now trek it every season.
Can foreigners trek here?
No. The official booking portal states that foreign nationals are not permitted to undertake the Agasthyarkoodam trek.
Is KeralaTrekking the Forest Department?
No. We are an independent trek organiser. We help you get your forest permit as part of a guided batch, but the permit itself, the season, the quota and the rules come from the Kerala Forest Department.
