About This Route
Kala Patthar (5,644m) offers a non-technical mountaineering ascent from Gorak Shep, the gateway to Everest Base Camp at 5,364m. Follow the rocky trail past EBC viewpoint, scrambling steep scree and icy patches to the summit cairn for panoramic Pumori and Everest views. Ideal acclimatization climb post-Lobuche; 3-5 hours round trip, but technical in wind or snow.
Safety Considerations
AMS strikes fast at this altitude; ascend only after EBC arrival, descend if headache persists. Loose scree causes slips; high winds (60+ km/h) erode visibility. Ice on ridges post-dusk; start pre-dawn. Spring (April-May) best per Nepal Met Department. Permits via Sagarmatha National Park (NPR 3,000). Apply Leave No Trace: bury human waste above 4,000m, no single-use plastics.
