What Is the Altitude of Lugu Lake? Will You Get Altitude Sickness?

Before going to Lugu Lake, many people ask one question: what is the altitude of Lugu Lake, and will I get altitude sickness?

The simple answer: the lake surface is 2,690.7 m above sea level, and the vast majority of people will not get altitude sickness.

Lugu Lake altitude data

According to measured data in the book Lugu Lake: Regional Habitat and Cultural Evolution:

Lake surface elevation: 2,690.7 m
Lake area: 48.45 km²
North–south length: about 9.4 km
Average east–west width: 5.2 km
Maximum depth: 93.5 m
Average depth: about 40 m
Catchment area: 171.4 km²

Lugu Lake is a typical highland deep-water lake, formed by fault subsidence. It is ringed by high mountains and sits in a mountain hollow.

Will 2,690 m cause altitude sickness?

Generally speaking, around 2,700 m is the threshold line for altitude sickness.

Medically, some people may begin to feel mild symptoms above 2,500 m; above 3,000 m, most people have some degree of reaction.

At 2,690 m, Lugu Lake sits right on this threshold. In practice:

The vast majority of people will not have obvious altitude sickness.

Reasons:

1. Although the lake is at 2,690 m, the vegetation is dense, so the oxygen content is higher than in arid areas at the same altitude

2. Many people arrive from Lijiang (2,400 m) and have already partially adapted

3. Lodging and activities at Lugu Lake are all at the lakeside – no climbing involved

A minority may feel mild symptoms:

A slight headache on the first evening
Shortness of breath when walking fast
Poor sleep at night

These are normal adaptation reactions. They pass after one night's rest and do not require medication.

Situations easily mistaken for altitude sickness

At Lugu Lake, several situations are often mistaken for altitude sickness but are not:

1. A delayed reaction after Jade Dragon Snow Mountain

Many guests follow this route: Lijiang → Jade Dragon Snow Mountain (cable car up to 4,500 m) → Lugu Lake.

In this case, they had a reaction on the mountain the day before, then spent the next day in a jolting car on mountain roads. By the time they reach Lugu Lake they feel dizzy and nauseous, and blame the lake.

This is actually a combined effect of Jade Dragon altitude reaction plus carsickness, not Lugu Lake's doing. One good night's rest solves it.

2. Carsickness

The drive from Lijiang to Lugu Lake takes over four hours on winding mountain roads. People prone to carsickness arrive dizzy and nauseous, and easily misread it as altitude sickness.

How to tell: with carsickness, resting for an hour or two in fresh air makes it fade; with altitude sickness, the headache and nausea persist or get worse.

3. A cold

Day–night temperature differences at Lugu Lake are large, and nights are cold. People who dress too lightly catch colds – headache and body aches – and mistake this for altitude sickness.

How to tell: a cold brings a stuffy nose, runny nose and cough; altitude sickness does not.

Who should be careful

Although the altitude is moderate, a few groups should take care:

1. People with serious heart disease or hypertension

If you have serious heart disease or high blood pressure, consult a doctor before going. 2,690 m is not high, but it still puts some load on the heart and lungs.

2. Pregnant women

Pregnant women are generally advised against high-altitude destinations. Lugu Lake is not very high, but for safety, ask your doctor.

3. People who climbed Jade Dragon Snow Mountain the day before

If you reached 4,500 m and had a reaction, watch your condition the next day at Lugu Lake. If you feel unwell, rest and avoid strenuous activity.

Notes after arriving at Lugu Lake

Even though the altitude-sickness risk is low, a few points help:

1. No strenuous activity on the first day

On the first day, do not run, jump or play hard. Walk slowly and let your body adapt.

2. No alcohol

Better not to drink on the first evening. Alcohol worsens the risk of altitude reaction and disturbs sleep.

3. Keep warm

Day–night temperature differences are large; nights can be around 10 °C. Bring warm clothing and avoid catching a cold.

4. Drink plenty of water

High-altitude air is dry; drink water regularly to stay hydrated.

Summary

Lugu Lake is at 2,690.7 m, and the vast majority of people will not get altitude sickness.

You do not need to take Rhodiola in advance, nor carry an oxygen cylinder. Just come and enjoy yourself.

If you are still worried, take the first day slowly, avoid strenuous activity, keep warm and drink water. After one night, you will be fully adapted.

Lugu Lake is not Tibet, not Highway 318. Do not worry about altitude sickness – treat it as an ordinary highland lake and come with ease.
