We took a 5-seater boat ride from Satpada for 3 hours, which cost us Rs.2300/-. I saw a lot of negative reviews, but we had a good time. We saw dolphins (3-4 sightings) and a lot of birds (they come very close to you, when you throw popcorns, etc in the lake. Actually this is not a very good thing to do as most people throw kurkure, fried bobby rings, etc which might be actually harming the birds in the long run..maybe OTDC should do something about this). After an hour's ride, the boatman dropped us off on an island from where we could walk to the beach on the other side. There was also a shack on the island which served tasty sea food like prawns, fish, crabs etc fresh from the sea, along with tender coconut. We spent an hour here and then the return ride was again around an hour (so total 2 hours). There are many points in Satpada from you can start the ride and the one that we took was from the actual Satpada town.
