Cox's Bazar is Bangladesh's most popular tourist destination — home to the world's longest natural unbroken sea beach at approximately 120 kilometres, stretching from Teknaf in the south to Cox's Bazar town. Since 2023, it has also been directly connected to Bangladesh's national rail network, making it possible for the first time in history to travel from Dhaka to the beach by train.

The Cox's Bazar Express (Train 795 Dhaka–Cox's Bazar; Train 796 Cox's Bazar–Dhaka) departs Dhaka Kamalapur and arrives at Cox's Bazar Railway Station (Ramu) in under 9 hours following the 2026 schedule revision. Key stops along the route include Comilla, Feni, Chittagong, and Dohazari Junction. The Dohazari–Cox's Bazar segment (the final 2 hours) passes through coastal hills and mangrove terrain — arguably the most scenically dramatic railway section in Bangladesh.

Cox's Bazar Railway Station is located at Ramu, approximately 15 kilometres inland from the main beach strip along Marine Drive. From the station, hire a local CNG auto-rickshaw (approximately 150–250 taka) or ride-sharing service for the short road to the beach hotels.

Best season: October to March offers the most pleasant beach weather — cool, dry, and low-wave conditions ideal for swimming and beach walks. Monsoon season (June–September) brings rough seas and heavy rain, though the lush green hills and reduced tourist crowds have their own appeal.

Key attractions: (1) Cox's Bazar Sea Beach — the world's longest; best sunrise section is at Laboni Beach Point, sunrise end at Himchari. (2) Inani Beach — 25 km south of Cox's Bazar town; rocky coral formations and clearer water. (3) Himchari National Park — 12 km south; waterfalls, viewpoints, and forest. (4) Saint Martin's Island — 9 km corallian island at Bangladesh's southern tip; accessible by ship from Teknaf (3 hours). (5) Ramu Buddhist temples and monastery complex — 8 km from station.

Book Cox's Bazar Express tickets as early as possible — this is Bangladesh's most in-demand train during peak tourist season (October–March) and Eid holiday periods.
