About this trail#
The Biligundulu–Rasimanal trail follows the banks of the Cauvery River from the village of Biligundulu to the Rasimanal Forest Camp. Operated by the Tamil Nadu Forest Department through the Trek Tamil Nadu initiative, the route follows the path used by forest guards for regular patrols. Much of the trail remains close to the river and crosses several seasonal streams before reaching the forest camp. During periods of high water in the Cauvery, these stream crossings may become impassable, making it impossible to complete the trek. Plan your visit during a season with lower water levels. Mobile reception is generally unavailable near the trailhead, so contact the Trek Tamil Nadu representative before crossing the Poomarathukuzhi Forest Checkpost, which is typically the last location with mobile coverage. Since the trail stays close to the river, many hikers choose to take a dip in the Cauvery and may wish to carry a change of clothes.

Trail reports#
Trail conditions and experiences shared by hikers who've done this route
We visited the trail when flooding in the Cauvery River had led to its temporary closure, allowing us to complete only the initial section. The route normally involves crossing multiple shallow riverlets before reaching the destination. During our visit, these crossings carried significantly more water due to the flood, making it impossible to proceed safely beyond the accessible section. The final stretch could not be completed because the swollen riverlets blocked further progress.
Wildlife & Nature#
Wildlife activity is evident along this trail. The forest guide carries fireworks as a precaution against elephants, reflecting their presence in the area. Elephant dung has been observed along the route, while crocodile footprints have been seen on the riverbanks. We also spotted an otter in the Cauvery during the trek.
