I will be taking a plane from Kathmandu to Bhaktapur. From there I don't know how to get from Bhaktapur to Kakarbitta and then on to Darjeeling. Can I take a taxi the entire journey? Do I have to change taxis at the border of Nepal and India. Has anyone taken this route and can give me information on how this trip worked for you?I'm not interested in crowed bus travel!
