For most travellers the best Everest helicopter tour is the shared seat via Lukla, Pheriche and Syangboche below Hotel Everest View: it is the most-reviewed helicopter flight on this site, the listing names the group size of five passengers and a pilot, the fees to pay on the day and hotel pickup in Kathmandu.
If a landing at Kala Patthar is the reason for your trip, take the shared seat with Kala Patthar and Everest Base Camp on the itinerary. If your group wants the helicopter to itself, the private chartered helicopter with a guaranteed Kala Patthar landing on the listing is the pick; it has few reviews so far, and you check on the booking page what the price covers. If the budget decides, start with the shared seats: our price page lists every helicopter flight here from the lowest starting price up, with the fees each listing names for the day.
