Cox's Bazar sea beach is the longest sea beach in the world, 120 km 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. As 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, the world's longest and widest with over 100 miles of unbroken sand. Things should be quieter here, but still expect to draw some attention.
