Hi all, Im planing a trekking trip to Mt. BC in Octobre. The plan is to do the trip independently, without any travel or trekking agency, from Kathmandu - Lukla- Namache Bazzar- Mt. BC. Octubre will be a pick time for trekking in Nepal and ill will have about 3 weeks to do it so just wonder if anyone can give me any advice on; 1. Flights from Kathmandu to Lukla. I know that if you travel independently you have to book it when you there. how long it can take as I get a restricted time for the trip. 2. Altitude Sicknes - i have read a bit about it but any tips from someone that been there? ???????????????
