Tilicho Lake or Annapurna Base Camp, here's which one deserves your 10 days in the Annapurnas

Pick Annapurna Base Camp (4,130 m) if you want the classic Annapurna amphitheatre in 9 days with a manageable altitude. Pick the Tilicho Lake trek (4,919 m) only if you are fit, have trekked above 4,000 m before and can afford the extra two days and about US$530 more solo. Tilicho is the harder, higher and quieter walk; Annapurna Base Camp is the better first Annapurna trek for most people.

Which trek is harder, Tilicho Lake or Annapurna Base Camp?

Tilicho Lake is harder. It tops out almost 800 m higher, and the final push to the lake is a long, exposed day at an altitude where altitude illness is much more common. Annapurna Base Camp is a sustained climb but stays under 4,200 m, which most fit walkers handle with a sensible schedule.

What does the altitude guidance say about each?

The US CDC advises that above about 2,750 m (9,000 ft) you raise your sleeping altitude by no more than roughly 500 m (1,600 ft) a day, and take an extra rest day for every 1,000 m (3,300 ft) climbed. Both treks need that discipline. Tilicho asks more of it because the final stretch spends longer at the heights where the CDC says the body needs time to adjust, which it puts at up to about 5,200 m.

If you have never been above 3,500 m, do not make Tilicho your first high trek. Annapurna Base Camp is the proving ground, and a sound ABC trip tells you honestly whether you cope with altitude.

How much more does Tilicho Lake cost, and is it worth it?

Tilicho costs US$530 more solo, US$460 more per person for two or three, and about US$430 more per person in a group of four to seven. You pay for two more days, a longer drive to Besisahar rather than the short run to Nayapul, and more remote lodging. It is worth it if you want fewer people on the trail and a lake at nearly 4,900 m. It is not worth it if your goal is the classic Annapurna sunrise, which ABC delivers better.

Who this suits, and who it doesn't

Annapurna Base Camp suits fit first-timers, couples and small groups who want a headline Himalayan trek in 9 days. Tilicho Lake suits experienced trekkers who want a higher, quieter route and have 11 days. Neither suits you if you have a heart or lung condition you have not cleared with a doctor, or if you have only a week, in which case Poon Hill or a short Mardi Himal trip is the better fit.

You can compare the two on our 9-day Annapurna Base Camp itinerary and our 11-day Tilicho Lake trek.
