Day Trips from Chittagong

This ridge-to-reef trip begins with a humid climb through semi-evergreen forest where macaques scream from the canopy and ends at a 1,000-year-old Hindu temple where incense coils into mountain fog. Forty-five minutes up Chandranath Hill buys you a sweep of Bay of Bengal blue that, on clear days, fades into the hazy outline of Burma.

Bangladesh's biggest man-made lake splinters into a maze of blue inlets between wooded hills, with tribal villages perched on bamboo stilts above the water. Drifting by boat feels like gliding through a half-drowned forest: kingfishers streak turquoise overhead, and the faint scent of woodsmoke drifts from kitchen fires you cannot see.

A British-built reservoir turned weekend playground lies cupped in a ring of hills that bounce roller-coaster screams back and forth. Dawn mist lifts from tea-dark water while you paddle past submerged quarry tracks left by the Raj.

Where the Karnaphuli River spills into the Bay, cargo giants come to die. Rusted hulls line the shore like an industrial graveyard at sunset. The scene jars: fishermen knot nets between oil-streaked propellers while diesel fumes mix with ocean salt on the wind.

Begin with a steep march up Batali's concrete steps where morning exercise groups wheeze beside you, then drop down to Naval Beach where the Navy band sometimes rehearses as the sun sinks behind bobbing trawlers.

Broken brick stupas rise from the sal forest like ancient molars, their terracotta still warm from sunrise. The 7th-century monastery ruins feel deserted enough for a film set, only wind in the trees and the scrape of an archaeologist's trowel disturb the quiet.

Bangladesh's lone coral island can be done as a long day if you board the 6am Teknaf boat and ride the 3pm back. Water shifts from river-mud brown to impossible turquoise, and the beach underfoot is pure crushed coral that clicks like plastic shards.
