On our way back, we went to Kala Pathar which is a snow covered mountain and tourists visit this place to play and enjoy the snow at the top. (P.S. you can either do Zero Point which is near Lachung or Kala Pathar which is near Lachen. Both the places are known for attracting tourists to enjoy the snow). This place requires permission (taken care by the driver) and some additional charges to visit the location
After all the excitement of EBC, and being literally dead when we came back to Gorekshep, we decided to climb Kala Patthar the same day.The tour companies usually take people interested in doing the same either in the wee hours of the morning to see the sunrise or next day evening to see the sunset. However, our group was a bunch of super enthusiasts :)
On the top of Kala Patthar (5500m), the oxygen levels at this altitude is well below 50%. From here you get the best views of Everest as well as a panoramic view of all the highest Himalayas peaks.
