The river first proceeds through a large shola then past the Muthuvar settlement of Olikkudi at 10.331°N 77.1435°E / 10.331; 77.1435. There is another small village #2 at 10.3553°N 77.1839°E / 10.3553; 77.1839. There are Kerala and Tamil Nadu border checkpoints on either side of the river where a SH 17 road bridge crosses the river at 10.35241°N 77.21775°E / 10.35241; 77.21775. 2 km east it is joined from the south by the Pambar River at Koottar where a comfortable tree house accommodation is available.

Tributaries
The river is joined by a small stream from the south at small village #2. 2 km east of the NH 17 road bridge the river is joined from the south by the Pambar River at Koottar. The western part of the Manjampatti Valley catchment basin drains into the end of the Chinnar River. This Valley is drained by the stream Ten Ar and a smaller unnamed stream 2 km to its west. The unnamed stream is the N-S political boundary between Tamil Nadu and Kerala. The top of the ridge above this stream to the west is the western limit of the catchment. This unnamed stream joins the Pambar River at the point they both join the Chinnar River at the north west corner of the Valley.
