Tara Air is starting commercial hot air balloon flights with two balloons from the first week of April, 2010 targeting Nepal Tourism Year-2011. Tara Air has already launched “The Balloon Fiesta” in Pokhara, some 200 km west of Kathmandu, from March 23, 2010 and has delegated five days for trial runs.
Hot Air Balloon flights were launched way back in VISIT NEPAL 98 and continued till the early noughties yet due to the fall in demand it was halted since then. The Tara Air website does not look like its been updated but if theres any enthusiasts out there then ringing them up would be a better way to communicate with them. Price for one flight for a foreign national is expected to be roughly $240 USD each.
This is going to be one of the quite adventures in Nepal.
