Hari runs some excellently well-oiled (and flexible!) treks and if you decide to partake, you’ll be able to basically sit back and enjoy a hassle-free trek experience fully able to ejoy the incredible sights that the Himalayas have to offer without virtually any logistics to worry about. I found his staff to be well-trained and very professional, if a little on the quieter side, and I felt taken care of the entire time. Personally, I would perhaps have liked a little more interaction with my guide or additional information about what we saw throughout.
If you’re thinking of doing the ABC via Poon Hill trek, I’d recommend purchasing a SIM card beforehad (Telecom NOT Ncell), and to consider doing the trek in a group setting, which I think the company is better suited to cater to. Also note that late May sees remarkably fewer visitors than April, especially in the first stages of the trip. All things considered, Hillary Step Treks is a reliable, secure and tested partner to link up with!
