This vast boundary passes through five Indian states, each offering a unique mix of landscapes, traditions, and cross-border interactions.

Let’s explore the five states that share their borders with Bangladesh and understand their importance.

1. West Bengal – The Longest Border

West Bengal has the longest boundary with Bangladesh, stretching nearly 2,216.7 kilometres. The border runs through fertile plains, rivers, and historical towns like Murshidabad, Malda, and North 24 Parganas. This stretch plays a vital role in trade, transport, and cultural exchange, reflecting centuries of shared heritage between the two regions.

2. Assam – The Riverine Connection

Assam shares around 263 kilometres of border with Bangladesh. The line runs through lush lowlands and riverine belts in the state’s south-western region. Known for its scenic landscapes and tea gardens, this border area supports local trade, migration, and ecological diversity.

3. Meghalaya – Hills Touching the Neighbour

The border between Meghalaya and Bangladesh extends for about 443 kilometres, winding through hills and dense forests. The areas of East Khasi Hills and West Jaintia Hills are particularly scenic. The region is known for its peaceful border relations, tribal heritage, and growing potential in tourism and cross-border trade.

4. Tripura – Surrounded on Three Sides

Tripura shares nearly 856 kilometres of border with Bangladesh — the second longest after West Bengal.
