Everest Base Camp Trek topped with a hike to Kala Patthar is absolutely worth it. While the trek to Everest Base Camp is mere trekking, adding Kala Patthar to it allows you to garner spectacular views of the Everest alongside Lhotse and Nuptse. After you have acclimatized to 5,500 meters / 18,045 feet, the trek is very much do-able for any fit trekker.
