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 fishermen 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 belonged to the five star resort The Lalit Golf & Spa Resort, located on this beach, and having hurdles around it. This resort is very well suitable for a person longing for peace and quietness, and having a big bank account.
Accommodation cheaper than five star I don’t recall seeing in Raj Baga Beach. But there is on the other Goan beaches, which you can find in the linked article.
