Cox's Bazar has one of the longest sea beaches in the world

Cox's Bazar has one of the longest sea beaches in the world, 120 km (75 miles) long.

For Bangladeshi's it doesn't get much better than Cox's Bazar, the country's most popular beach resort. Sort of a Cancun of the east, it's choc-a-bloc with massive cement hotels and gaudy over-development catering largely to the country's elite. To a foreigner it likely won't compare to other beach vacations you may have taken, but it's still interesting to see how the Bangladeshi's live it up. The beach is crowded, especially near the Hotel Motel Zone, a large cluster of more upmarket hotels. Expect lots of attention, and expect to stay fully clothed.
30 km south is Inani Beach. Things should be quieter here, but still expect to draw some attention.
Cox’s Bazar is a town: on the southeast coast of Bangladesh. It’s known for its very long, sandy beachfront, stretching from Sea Beach in the north to Kolatoli Beach in the south. Aggameda Khyang monastery is home to bronze statues and centuries-old Buddhist manuscripts. South of town, the tropical rainforest of Himchari National Park has waterfalls and many birds. North, sea turtles breed on nearby Sonadia Island.
