I can't speak highly enough about my experience with Himalayan High. My wife and I wanted to do the Har Ki Dun trek but didn't want to be part of one of the many larger trips most trekking companies plan. I reached out to Himalayan High about the "self guided option" they listed on their website and ended up getting a totally bespoke trip for just my wife and I. Planning and communication was excellent leading up to the trip ( thanks Suman!) and our guides (required in a national park) were incredibly knowledgeable and friendly, not to mention great cooks. We are already thinking about our next Himalayan trek and will definitely be working with Himalayan High.

We did a recent Sandakphu trek with Hinalayan High. Few months before the trip, inquiries made to the company were promptly replied by Mr Suman. He also offered different options that would fit our fitness level and schedule. Our many questions and concerns were addressed to enable us to decide on the itinerary that suited us. There was also transparency in the costs and added fees. We opted for private trek so that we could go at our own pace. The lodging arrangements were made with our needs taken into consideration. (We preferred private rooms, being both ladies). While we did not expect 3-4* star hotel accommodations, the rooms were comfortable enough with sufficient blankets to keep us warm at night. We were prepared for shared bathroom facilities in a couple of homestays, having experienced so in previous treks. Due to health issues, we were not able to do the original long trek. But in exchange, our altered trek itinerary gave us unexpected blessings, additional day at Sandakphu to marvel at the scenery and catch glimpse of Everest on clear mornings. The alternative trek led us to a relatively new and clean Homestay with ensuite rooms down at Gurdum. It was situated at a picturesque spot with sunrise view from our room. There was even hot water available for a good bath after few days of trek. What luxury! Food by the homestay host was also delicious - fried noodles, and dumplings, with their home-made chilli paste. The stay was so wonderful that we chose to stay an additional day. It certainly exceeded our expectations. We are thankful to our guide, G.D. for his thoughtfulness. He prioritised our safety, ensured that we were comfortable and well fed. Mr Raju of the trekking company also checked in on us a few times to ensure that we were alright especially at Sandakphu. We are also grateful in the quick adaptation of itinerary to make the trek more manageable for us. We had a good laugh when we learnt from other trekkers further on the route that they had heard about the group who had to alter trek route due to health reasons....how news passed, but also shows the connectedness of the trekking community in that area. What we also enjoyed were the opportunities to get to know the people and hear about the history of the places we visited. Their love for the land and passion in what they do certainly came through in the conversations with G.D. and Mr Suman. Will certainly recommend Himalayan High to my friends.

We had an unforgettable experience trekking in Sikkim with Himalayan High!! From start to finish, everything was impeccably organized, and each member of the team went above and beyond to make our journey up to Dzongri La truly memorable. Special thanks to Suman, the organizer, for ensuring that every detail was thought through, and to our trek leaders Raju and Durga, whose expertise, warmth, and patience made us feel safe and cared for every step of the way. The entire support team was fantastic – cook Raj, assistant cook Anand, and our Yak guy Pemba. They all added to the experience in meaningful ways. A huge highlight was the food, which was consistently delicious and energizing – it played a big part in keeping our spirits high throughout the trek. We were honestly amazed by the quality and variety, especially given the remote mountain setting. Overall, this team was professional, attentive, and genuinely dedicated to making sure we had an amazing time. We wholeheartedly recommend this company to anyone looking to explore the beauty of the Himalayas. We’re already looking forward to our next trek with them!

We did the Kang Yatse 2 trek with Himalayan High and we were more than pleased about the care they have for the people. Montu was a really awesome guide and all the team from the chef, the boys that helped and everybody took so much care about us to feel comfortable. The food was awesome(we even had pizza and french fries some times), the tents and sleeping bags(we never felt cold at night), the toiletts, athmosphere and everything exceeded my expectations.

I climbed Kang Yatse 1 with Himalayan High and honestly it was one of the best trips of my life. Being a solo female traveller I was nervous about the trip beforehand but I was so well looked after by the team at Himalayan High that my concerns faded very quickly. The first week of this trip was a rotation between different acclimatization walks in Leh and a homestay in Rumbak, which was absolutely beautiful and I really enjoyed having these experiences as part of my acclimatization journey because the experience then wasn't just about reaching the summit. The second week was spent at basecamp with rotations to camp 1 and summit camp. This bit was really well thought out to ensure I was acclimatized and ready for summit but also really adapted to my needs and the spare summit day was absolutely crucial to what I needed. The team who looked after me at base camp were absolutely amazing. Because I was travelling alone I really felt we got to know eachother really well and I left with some lovely new friends. I was so well fed for the whole trip - the food was always absolutely delicious and plentiful! The water situation was also perfect - the water was boiled and treated before I got it. I cannot fault Himalayan High - everything was thought about, I felt so safe and well looked after at all times and I had so much fun on this trip with the team and learned SO much from them. I would definitely not hesitate to book with Himalayan High again- in fact I will probbaly do another trip with them in the not-too-distant future.
