There are 19 Gokyo Lakes in total in the chain, located in the Solukhumbu district of Sagarmatha National Park. The main village of Gokyo is found on the shore of Gokyo Cho (sometimes confusingly called Dudh Pokhari), while the largest of the Gokyo Lakes is Thonak Cho (the fourth lake). Gyazumpa Cho, Tanjung Cho and Ngojumba Cho round out the 5 main lakes (as you may have guessed by now, "cho" is the Nepali word for "lake").
