Do I really need a guide?

Yes, as of 2023, the Khumbu region authorities require all trekkers to be accompanied by a licensed guide.

How do I handle the cold at night?

Tea houses are not heated. Your sleeping bag is your primary warmth; wear your thermal layers inside the bag and keep your water bottle under the covers to prevent freezing.

How to Trek to Everest Base Camp

To trek to Everest Base Camp, fly from Kathmandu to Lukla and hike for 12 days to reach the base camp at 5,364 meters. You must hire a licensed guide or porter through a registered agency, as independent trekking is no longer permitted in the Khumbu region.

Secure your permits. You need the Khumbu Pasang Lhamu Rural Municipality Entrance Permit and the Sagarmatha National Park Entry Permit. Most trekking agencies handle these as part of your package.
Train for altitude. Spend 8 weeks doing aerobic exercise (hiking with a 10kg pack, running, or cycling) at least 4 times per week to prepare your lungs for high-altitude thin air.
Book your Lukla flights early. Flights to Lukla often divert to Ramechhap during peak seasons. Book your flight at least 3 months in advance and buffer an extra 2 days in your schedule for weather-related flight delays.
Acclimatize properly. Follow the 'climb high, sleep low' rule. Specifically, schedule mandatory rest days in Namche Bazaar (3,440m) and Dingboche (4,410m) to allow your oxygen levels to stabilize.
