Raj Baga Beach is a beautiful, rather small silent beach located in South-Goa, in-between Patnem Beach and Talpona Beach. When I visited there, I didn’t see any other tourists, just a few fishermen’s huts.
One fisherman there came by and offered me a boat ride along the nearby Talpona river, but otherwise there was no activity for tourists, except a golf course, which was arranged by the five star resort The Lalit Golf & Spa Resort, located on this beach, having hurdles around it. This resort seemed very suitable for a person longing for peace and quietness, and having a big bank account.
Accommodation cheaper than five stars I don’t recall seeing in Raj Baga Beach, but you will find it on the other Goan beaches, which I’ve written about in the linked article.
