Tourism is the most significant contributor to Kalimpong's economy. The summer and spring seasons are the most popular with tourists, keeping many of town's residents employed directly and indirectly. The town—earlier an important trade post between India and Tibet—hopes to boost its economy after the reopening of the Nathu La (pass) in April 2006. Though this has resumed Indo–China border trades, it is expected that Kalimpong will have a better chance of revival as a hub for Indo–China trades if the demand of local leaders for reopening of Jelep La pass also is met.
