12-Day Everest Base Camp Trek: Lukla Flight, Kala Patthar & Sherpa Villages
Select participants and date
The plane drops out of the clouds and Lukla's tiny runway appears pinned to the hillside — a raw, immediate reminder that this is where the real journey begins. From that first step on worn stone and packed-earth trails, the route climbs through rhododendron forest, crosses swing bridges, and threads its way into the open, raw geometry of the high Himalaya. Each day the air thins and the views sharpen: terraced villages give way to prayer-flag-flecked ridgelines, and the Khumbu Glacier starts to loom like a slow, white river.

Adventure Tips
Pace for acclimatization
Schedule buffer hikes and rest days (Namche Bazaar and above Tengboche) rather than pushing distance — acclimatization beats speed at altitude.
Carry sufficient cash
ATMs are limited on route; bring Nepali rupees for permits, tips, and hot drinks in tea-houses.
Prepare for Lukla flight delays
Weather frequently delays flights to Lukla; plan flexible international connections and a spare day in Kathmandu.
Footwear and footing
Use stiff-soled hiking boots and consider trekking poles for rocky steps and loose moraine near Gorak Shep.
