Why the Bali beaches are special?

With an anxiety to find out why Bali is popular for its beaches, i found a Bali guide of Hillmannwonders that depicts few reasons for its pouplarity.

As it quotes”
Bali has many long, palm-fringed, white-sand beaches kissed by clear, warm tropical waters. There are beaches for every taste. Some are packed with sunbathers and lined with convenient shops, eateries, bars and other tourist facilities. Others are populated with big-wave-seeking surfers. Still others are serenely off the beaten path and shared by few people.

Best known beaches

West Coast
They face the warm Indian Ocean waters – and are admiringly oriented for sunset watching.
Jimbaran Beach
Lovely location. Favorite of sunbathers seeking a long, quiet, scenic tropical beach. Never a blanket of people, even during peak season. Luxury resort hotels fronting the beach are discreetly semi-hidden from view.
Kuta Beach
Deservingly praised for its length and white sands, though the beach in front of Kuta’s main tourist facilities can become packed.
Legian Beach
Adjacent and similar to Kuta Beach, though not quite as busy and commercialized.

East Coast
These lie along the body of water between Bali and Lombok Island.
Nusa Dua Beach
Populated with many international-style five-star resort hotels. Can occasionally become moderately crowded.
Sanur Beach
Once Bali’s most popular beach. Still pleasant, though waves in recent decades have eroded some sand.
Candi Dasa Beach
Half as busy and developed as Sanur and Nusa Dua’s beaches, but has in recent decades suffered even more sand erosion than Sanur Beach.

North Coast
Lovina is the most touristed destination on Bali’s north coast. It is known for its “black sand” beaches (”gray” would be more accurate).
Positive
The Lovina area is less developed and commercialized than tourism centers like Kuta.
Negative
The beaches are hardly tropical paradises. They experience the sometimes hot and humid tropical Bali Sea climate.
“Lovina” is a collective name for a string of seaside villages.
