Everest base camp trekking in Nepal is one of my best adventure trip as it is truly beautiful place. we had 30 minute flight from Kathmandu to lukla than we walked about 4 to 6 hours a a day each day till we are back to lukla. in total we walked 11 days than back to Kathmandu. this trip provided me such an immense opportunity to experience the local sherpa culture, vast himalayan terrain and unspoiled walking paths. if you are looking for everest trekking and if you are simply fit you can make it easily just follow your guide and care about food than you can make it. cheers and thank you safe holiday.
