We completed the trek in just 13 days. Everest Base Camp Trek is full of adventure. Make sure your guide is experienced and knows the nitty-gritty of the trek. Our guide was superb and fast with booking room, and handling thing. When we were supposed to reach Dingboche at 7 pm, we couldn't reach and he grabbed torch light from the teahouse and retraced his steps back to us for our comfort. This was a great gesture. And if I have to sum up, EBC trek is a must-do trek once in a lifetime.
