Sindhu Beach is located in Sanur, it is a really laid-back place with an authentic feel about it. The locals seem to enjoy their time there as well as tourists. There are tons of places to get food and drink and often very affordable. It is very flat for walking and the sea is very calm. Like many other beaches along Sanur, it has a beautiful view of sunrise.
It is safe for swimming, even though not many people will do that as it is more like a place for sightseeing and fishing.
