Tonse is a combined village, which includes Tonse West and Tonse East situated about 8km (05miles) from Udupi on the western coast of South India, between the Arabian Sea and Western Ghats. Tonse village is about 68km (42miles) to the north of Mangalore.
Tonse is bounded on its western side the Arabian Sea while on the eastern side the Suvarna river runs, creating a number of islands in its delta before it finally merges with the sea at Kodibengre.
Towards the northern tip of Tonse there is Kodi Bengre where Suvarna river flows into Arabian Sea. This creates a delta with numerous islands known as Kuduru. This is popularly known as "Delta Beach". Bengre is a thin strip of land almost 4 km long and holds back the sea on the west and the river on the east. At some stretches this strip in barely 50 metres wide.
In the delta of Suvarna, a group of about a dozen islands, covered with coconut palms and surrounded by clear blue waters.. Recently many House Boats are seen in the backwaters of Hoode.
A hanging bridge, which attracts visitors, connects one of the better-known islands, Thimmankudru to the mainland. The Hanging Bridge was constructed by 2 Karnataka Engineer NCC and the bridge was named as Deepak in memory of a late NCC Cadet. The complete material for construction of this bridge was made available by local people from their own private funds, the bridge was designed by Officer Commanding 2 Kar Engg NCC and was constructed by NCC Cadets of REC Surathkal (NIIT), Manipal Institute of Technology and NITTE College of Engineering in the Year 1991. Total time taken to construct the Bridge was about twelve days. The piers had been constructed by local villagers prior to this. Now a new bridge is being constructed to link the island by a motorable road.
Three miles off the seacoast are the St. Mary’s Islands, a tourist spot, (locally known as ‘Tonse-Par’ meaning, ‘beyond Tonse’), reachable from the port town of Malpe, by powerboat or country craft.
