Agasthyarkoodam Trek: The Complete Guide

Agasthyarkoodam is a 1,868 m peak in the Agasthyamala Biosphere Reserve, in Thiruvananthapuram district at the southern end of Kerala. The trek to the top is widely regarded as the toughest trekking route in the state: 50+ km over three days, through forest and open grassland, ending in a steep rock climb with safety ropes. At the summit stands a statue of Sage Agastya, which is why the mountain is also a place of pilgrimage.

This guide gives you the full picture in one place, then points to the detailed pages for route, permits, season, fitness and packing. If you decide to go with a guided group, you can ask us for the next KeralaTrekking batch at the end.

What is the Agasthyarkoodam trek?

The trek starts at the Bonacaud forest picket station, about 61 km from Thiruvananthapuram city. From there the trail climbs through rainforest and grassland, passes places such as Muttidichan Theri and Pongalappara, and reaches the Forest Department camp at Athirumala. The last section is a bare granite face where fixed ropes help trekkers reach the peak.

Entry to the peak and the area around it is restricted by the Kerala Forests and Wildlife Department. The trek is run as a controlled programme during a defined season, and tickets are booked online by registered applicants. There is no walk-in or private access to the summit trail.

Why trekkers choose Agasthyarkoodam

• The challenge. Long days, steep ascents and a rock-climb finish make it a real mountain trek, not a day hike.
• The forest. The route runs through a UNESCO-designated biosphere reserve, known for its rich plant life and medicinal plants.
• The views. Open grassland sections and the summit give wide views across the southern Western Ghats.
• The meaning. The peak is associated with Sage Agastya, and the summit idol draws pilgrims as well as trekkers.

How long does the trek take?

Most groups plan three days and two nights: walk to Athirumala on day one, climb to the peak and return to camp on day two, and walk out to Bonacaud on day three. Faster trekkers who reach Athirumala early enough on the return leg can sometimes finish the descent the same day, but the Forest Department’s rules and the group’s pace decide this on the ground. Read the day-by-day route and itinerary for distances and timings.

How hard is it?

Hard. 50+ km over three days, with a long first day (about 20 km), a steep stretch that trekkers describe as knee-breaking, and an exposed rock section on the final climb. It is doable for fit beginners who prepare, but it punishes people who arrive unprepared. See difficulty and fitness for a realistic training plan.

Permits and booking

You cannot trek here without an official ticket. Tickets are limited per day and slots are hard to get, and you must carry a fitness certificate and the prescribed documents. KeralaTrekking helps guided-batch trekkers get the forest permit. Read permits and cost and see guided batches for current dates.

Best time to go

The Forest Department’s own seasonal trek runs from around mid-January into February, in the drier, cooler months, and KeralaTrekking also runs guided batches in other months. Wet rock makes the final climb far harder, which is a key reason the season sits in the dry window. See best time to trek.

Rules you must follow

• No plastic. Carry water in steel or reusable bottles.
• No puja materials, and no pongala at Pongalappara.
• No alcohol or narcotics. Zero tolerance.
• Foreign nationals are not permitted on this trek.

Going with KeralaTrekking

KeralaTrekking is an independent trek organiser based in Kerala. We run guided batches so that first-timers and small groups can do harder treks with experienced leads, clear instructions and a group around them. We are not the Forest Department. Permits are issued by the Forest Department, and we help you get them as part of a guided batch. We also coordinate the batch, tell you exactly what to prepare, and stay in touch until you are on the trail. Read more about us, or go straight to guided batches.
