A Path Less Travelled…the Sinhagala Traverse

Sri Lanka’s Sinharaja rainforest has gained significant attention in the past few decades for its biodiversity and large protected area of forest in a densely populated corner of the island nation. It remains a veritable oasis of the lowland tropical rainforest vegetation that once covered much larger areas of the island’s “wet-zone.” I’ve been fortunate to be able to take student groups to Sinharaja over the past seven years and have also enjoyed several personal visits. The field study trips are usually oriented around the IB Diploma Geography Internal Assessment that requires field-work. Increasingly we have been looking to study human-ecosystem relationships and interactions (with the aid of GIS and spatial data of the area) around the popular Kudawa entrance. However, there is much more to Sinharaja that few visitors see. and on a recent trip a group of friends and I had a chance to make a long traverse over little-used paths that connect the two major entrances.

This August a group of friends and I had a chance to make the  long traverse over little-used paths that connect the two major entrances of Sinharaja. We started in the west at the Kudawa entrance and ended in the eastern portions that my family and I had visited in May. Together with friends at the Rainforest Ecolodge we were looking to see if a day-long trek from the Kudawa entrance to the Pitadeniya exit was a feasible option to take a student group. We did the trek via Sinhagala, the “lion rock” that is a significant point at the center of Sinharaja. Though few people actually visit it, the peak has significant cultural importance and is associated with stories of the advent of the Sinhalese people. Sinhagala is roughly 17 km from the core-zone entrance above Kudawa while on the map it is a shorter 10 km to Pitadeniya from the summit. Our team was composed of four friends and faculty members from the Overseas School of Colombo. As per park rules, we hired a guide to take us to Sinhagala peak (he returned after leaving us at the peak). Meanwhile our friend Krishan from the Rainforest Ecolodge organized a team to come up and rendezvous with us at Sinhagala.

The path to Sinhagala is arguably one of the most beautiful rainforest walks that you can do in South Asia. The trail follows a long overgrown logging road that snakes into the heart of the reserve and exposes you to amazing swathes of primary and secondary forest. The walking is not challenging from the perspective of physical terrain and the altitude gain is less than 300 meters. However, the path does take time and for this reason most visitors to Sinharaja are reluctant to invest 8-9 hours of walking round trip to see it. If you are interested in stopping to watch bird flocks and look for snakes, lizards and other interesting creatures the walk can be frustrating since there is little time to indulge in such delights.

Most of the bridges and culverts have been washed out and it is difficult to imagine that 35 years ago large trucks were using the same pathways to decimate the timber of Sinharaja! Now the machinery is long gone and the forest has made a startling recovery such that most people can not distinguish between unlogged primary forest and tracts of secondary forest that had once been clear cut. In fact this is really the beauty of the Sinharaja story: the protection and restoration of a tropical rainforest through the efforts of citizens and scientists who helped raise awareness at a time when “rainforests” and “biodiversity” were not in the public’s vocabulary. In the 1970s forest was simply another commodity to be commercially exploited.  The tireless work of those individuals and civil society groups is now something that we visitors benefit from.

After a breakfast and tea at Martin’s Forest Lodge we set off at a good pace and were the first visitors into the tourist zone. The forest was waking up after a night of nearly continuous rain, but he day was to be free of serious precipitation. In the distance we could hear the sounds of mixed species flocks and the dull echoing, reverberations of the endemic Purple Faced Langurs (Trachypithecus vetulus).  A Sri Lankan Jungle Fowl (Gallus lafayetii) strutted across the road unconcerned by our presence- I think every visitor see (and probably feeds) the same bird. We heard the distinct wind up sounds of the more elusive Sri Lanka Spur Fowl (Galloperdix bicalcarata). This is an area that I usually walk through slowly in order to observe and appreciate lesser life forms. However, we had a long path to traverse and made fast time in this more easily accessible area.

At the research center (a place that once hosted the workshop for the mechanized logging operations) the trail thins and it is clear that the Sinhagala trail is a different sort of route. The path was overgrown with tree ferns, shrubs and pioneer tree species competing to take advantage of the break in the canopy. Every so often fallen giants of trees created barriers that we negotiated around, under or through.  The leaches very plentiful but the Kudawa leech socks allowed us to focus on more interesting creatures. Occasionally I would catch glimpses of frogs hopping away from the pathway. Giant Wood Spiders (Nephia maculata) were numerous as were the large millipedes (Spirotripetus sp.). We saw a third Sri Lanka Hump Nosed Lizard (Lyriocephalus scutatus) but did not spend time with it as we had with the male and female that we had seen in the tourist zone the day before (see photographs below). Enormous growths of pitcher plants (Nepethnes distillatoria) covered what were once ugly road cuts. They thrive in the brightly lit areas stripped of the thin topsoil. They thrive in the brightly lit areas stripped of the thin topsoil making up for the nutrient deficiencies with the insets that they digest.

Three hours after starting out the Sinhagala path left the old logging road trail and took us over several hillocks before following a boulder-strewn stream upwards. The dense forest make locating ourselves in the landscape impossible though we knew that we were at the base of Sinhagala. Moss-covered rocks in the stream slowed us down. In the last stretch the pathway followed a steep incline amongst the drooping lianas and buttresses of enormous forest giants. Granite boulders covered in gray-green lichens provided small sheltered spaces-perhaps more often used by leopards than humans in this very far away corner of Sri Lanka. And then the pathway abruptly passed though a break in vegetation and opened up over a cliff face. Through the break we were treated to a stunning panoramic view over the forest tracts of central Sinharaja. Below the cliffs was a scene of multiple valleys of rainforest canopy, sheltered by the rugged cliffs and hills that made up the range. To the East were the higher mist-shrouded ranges where we would go later that night. It wasn’t all unblemished landscape and in the distance were the clearcut slopes of land to be planted with tea. There were also the ubiquitous cell phone towers on the summits of several distant ranges to the south. This was our half way point and we breathed in the view while we waited for Krishan’s group to join us.

Krishan, his wife Indrika (who works with us at OSC), their two enthusiastic children and several others arrived on Sinhagala around 2:00. They were exhausted and drenched in sweat having just taken a very steep, overgrown trail up to the peak. Because of the hour there was little time for rest and we soon got going to descend on the trail that they had just spent so many hours climbing up. On the map it looked like a short distance but it ended up being a significant hike to get out. Krishan’s group had two guides and they were accompanied by Dulan Vidanapathirana who is a reptiles expert helping out at the Rainforest Ecolodge.  We set a good pace but with the impending darkness there was little time to appreciate the forest and it denizens. When we finally emerged at the Pitadeniya entrance it was dark and we were worn out in that most positively fulfilled way!

It was another two-hour, zig-zagged drive up to the Rainforest Ecolodge where we spent a night and morning recovering in comfort. I awoke to a flock of Blue Magpies- the signature endemic bird of Sinharaja- making a racket right outside my capsule-room.  Soon after I accompanied Dulan on a short walk before breakfast- enough time to take in the magnificent forest and learn about the areas geckos, frogs and shield tails. Unfortunately we had to get back and left before lunch to return to our jobs, demands and lives in Colombo. The traverse from Kudawa to Pitadeniya was unforgettable and it helped me plan for the upcoming trip in January. I will modify the challenge and take our students in smaller segments, allowing for a deeper appreciation of Sinharaja’s landscape and ecology.

  1. great article and photos Ian. I am now working with one of your old co-workers, Ray Lewis. We hiked the Tatra mountains together a week ago, and ‘discovered’ the Ian Lockwood connection.
