Gokyo Cho La Pass Trek in July

The fourth Gokyo lake begins rising in early July after months of draining, and the research paper puts the air above freezing from May to September. The Nepal Trekking Routes season guide says clouds often hide the mountains in the monsoon, so the clear views the route is sold on are a matter of luck.

The pass is the main reason to avoid this month. Our tour notes say the Cho La is risky during the monsoon, and Heaven Himalaya lists the season as generally avoided for rain, slippery trails and poor visibility. Day 11 is long, about 7 hours from Thangnak to Dzongla, and rain on loose rock and a glacier stretch is a different day from a dry one.

Lower on the route, the day 15 and 16 walks to Namche and Lukla take about 7 hours each in any month, and in July they are muddy. The Nepal Trekking Routes season guide adds landslides and leeches to the list for the monsoon months.

July is the emptiest month the park records. The Himalayan Times reported 125 trekkers entering between mid-July and mid-August 2024, against nearly 9,000 in the single month to mid-October. That is the whole park, not the Gokyo side, which our tour notes say is a fraction of the main trail in any season.

Which lodges on the Gokyo side are open is the question to ask before any other.

July flights leave from Kathmandu under our flight notice. HoneyGuide says the monsoon carries the highest cancellation risk, with airlines scheduling a single flight a day, and that weather in both Kathmandu and Lukla can stop flights.

A trek built on one spare day is a poor fit for July. If you go, book the international flight with the most flexible change terms on offer and add several days at each end.
