Hi All,
Im planning and intend to visit Bali with my girlfriend for a weeks, I have been there before 4 years, I want to be on beautiful lonely beaches. I know that in lovina but i never been in south part , bellow Kuta etc. Please advise me.
Thank in advance.


"Beautiful lonely beaches" and "Bali" no longer go together. Every beach of standard light coloured sand/blue water has been well populated with Warungs, hotels and sellers. Even Dreamland and Belangan are now well known.
"Not so beautiful, but lonely" can be found in the North East and along the west coast of Jembrana. Just North-West of Taman Rekreasi Pantai Soka is nice.
Rent a car and drive to the less touristy northern coast. You will find relaxing hot springs, water falls, volcano craters and lakes and lots of lonely, although not white and sandy, beaches. Most are of grey or black colour (lava origin), some are quite stony or have reefs in front of them. The East Coast has plenty of lonely beaches as well.
As white sandy beaches I would recommend
Padang Bai
(sometimes, depending on the current, can have trash coming in with the waves)
or
Dreamland (Although these days in high season, not so lonely anymore)
Around Uluwatu on the southern Bukit (hill) there are some secluded, mainly stony beaches as well.
Anyway - have a great trip!
