Sanur beach is very good for families with young children as no wild surf. However if you do want to surf you can outside the Reef by the Hyatt, boats will take you out at any time. It is also a great place to just totally relax or take a boat trip, snorkel or jet ski. It has a gorgeous paved beach walk from one end of the town to the other. There are lots of great restaurants along the beach and bars. Really enjoyable early morning or late afternoon. Sundays there is a market at the Sands which sells really nice locally made items.
One of my favourite places is Casablanca, Dine, Drink and Dance along the main street of Danau Tamblingan. They have live music every night and a nice crowd. Friday nights is fun there with free flow beer from 6-7pm. Monday nights Bamboo restaurant has a fantastic band and good food and is also one of my favourites.
You can access the beach from a few points or cut through one of the hotels. Sun beds can be rented for the day for 25,000Rp which makes it cheap and enjoyable.
The shopping is quite good with lots of stalls but also reasonably priced shops as well.
All in all it is a very relaxed atmosphere, you don't get hassled like you do in Kuta and it still retains a bit of a village life. Ceremonies can be experienced regularly and Sundays when all the locals come to the beach it is lovely to see.
