We did a 10-days trekking to Gokyo via the Renjo La Pass and back to Lukla with Shekar in November 2023. Everything was very well organized (flight from Kathmandu, Lodges, etc) and we felt well accompanied by Shekar so that we could just enjoy to trekking and the beautiful landscape. Shakar knows the region very well and can explain you a lot of things. I can only recommend him as a guide.
