Everest Base Camp Trek FAQ: 15 Expert Answers on Fitness, Permits and Altitude
The Everest Base Camp trek raises the same handful of questions for nearly everyone — how fit do you need to be, what do the permits cost, can you still go solo, and how scary is the altitude really. Here are straight, expert answers organized by topic, followed by a quick-reference table you can screenshot.
Fitness and difficulty
Reasonably fit, not elite. The EBC trek is long and high, not technically hard — no ropes, no climbing. If you can walk 5-7 hours a day on hills for two weeks, you can do it. The altitude, not the terrain, is what tests you. Train with hill walks, stairs, and multi-day hikes carrying a daypack for a few months beforehand.
How fit do you need to be?
How many hours a day will you walk?
Typically 5-7 hours, with the toughest being the 600m grind from Phakding up to Namche Bazaar and the high-altitude days to Lobuche and Base Camp. Distances are modest; it's the elevation and thin air that slow you down.
Do you need previous trekking experience?
No, but it helps. Plenty of first-time trekkers reach Base Camp. What matters more is the discipline to walk slowly, hydrate, and take the acclimatization days seriously.
Permits, TIMS and Sagarmatha
What permits do you need?
Two. The Sagarmatha National Park entry permit (~3,000 NPR) and the local Khumbu Pasang Lhamu Rural Municipality permit (~2,000 NPR). You can buy both en route or in Kathmandu.
Do you still need a TIMS card?
No — the old TIMS card is not used in the Khumbu anymore. The two permits above cover you.
Do you need a separate visa for the trek?
No. Your Nepal tourist visa (visa on arrival at Kathmandu: 15 days ~$30, 30 days ~$50, payable in USD cash) covers your entry. The permits above handle the trekking region.
Altitude sickness
How dangerous is the altitude?
This is the real risk of the trek. Above 3,000m, ignoring acute mountain sickness (AMS) can be fatal, and it can escalate to HAPE (lung fluid) or HACE (brain swelling). The good news: it's largely preventable with a slow ascent and honest acclimatization.
How do you avoid AMS?
Ascend slowly — never gain more than ~500m of sleeping altitude per day up high. Take the built-in acclimatization days at Namche (3,440m) and Dingboche (4,410m) and use them to "climb high, sleep low." Drink 3-4L of water daily. Watch for headache, nausea, and breathlessness — and if symptoms worsen, descend immediately. That's non-negotiable.
Should you take Diamox?
Many trekkers carry Diamox (acetazolamide) as a preventive, but consult a doctor first. It helps you acclimatize; it doesn't cancel the need to ascend slowly.
Cost
What does the trek cost overall?
Most people book an agency package covering guide, porter, permits, and the Lukla flight. On top of that, budget roughly $25-40 per day for food and lodging. Note that prices climb steeply with altitude — water can hit 300-400 NPR at Gorak Shep, a hot shower 500-800 NPR, phone charging 300-500 NPR.
How much cash should you carry?
More than you expect. ATMs vanish after Namche Bazaar — those are the last reliable machines, they charge high fees, and they often run dry. Everything above Namche is cash-only NPR.
Guides vs solo
Can you trek solo?
Not anymore, in most regions. Since 2023 Nepal requires solo trekkers to hire a licensed guide — Everest included. A reputable agency arranges the guide, porter, permits, and flights as one package. A guide also dramatically improves your safety margin on altitude decisions.
Do you need a porter?
Not required, but strongly recommended. A porter carries your main duffel so you walk with just a daypack — which makes the high days far more manageable. Tip ~$8-10/day for a porter, ~$10-15/day for a guide.
Gear
What gear is essential?
A down jacket, a -20°C sleeping bag, trekking poles, a headlamp (for the pre-dawn Kala Patthar climb), hand warmers, sturdy broken-in boots, and layers. You can rent most of it in Thamel for ~$1-2 per item per day at shops like Shona's.
Wi-Fi and connectivity
Is there Wi-Fi?
Yes, up to a point. Namche Bazaar has genuine Wi-Fi and hot showers. Higher up, connectivity gets patchy and pricey — many teahouses sell Wi-Fi cards, and phone charging costs 300-500 NPR per device. Consider it your chance to actually disconnect above Namche.
Best months
When should you go?
Two windows: pre-monsoon (March-May) and post-monsoon (late September-November). October is the standout — clearest skies, most stable weather. Avoid the monsoon (June-August), which brings cloud, mud, and flight cancellations, and skip deep winter unless you're prepared for brutal cold.
Get the season, permits, guide, and altitude plan right, and the rest of the trek falls into place. The walk to 5,364m beneath the Khumbu Icefall — and the golden dawn view of Everest from Kala Patthar — is well within reach for a reasonably fit traveler who respects the mountain and takes it slow — and when tired legs need a flat, warm week to recover, the palm-fringed backwaters of Alleppey in southern India are a classic post-trek unwind.
