Unfortunately, there is no high-quality and reliable Gokyo Ri Map available for free online. Still, if you're trekking in the Khumbu, you're going to need to take a physical map anyway. You can purchase the best Gokyo Ri Map online, which includes details for Gokyo Lakes, the entire Three High Passes Trek, and the Everest Base Camp Trek. Otherwise, you can pick one up in Thamel at any trekking shop.
