I have travelled with teams of Overland Escape on 6 occasions now and every single time the experience was wholeheartedly positive.
On two occasions, Tundup organised lengthy treks through remote parts of Ladakh, Zanskar and Nubra and his organisation was absolutely reliable and spot on on every occasion. The trekking teams we travelled with were excellent, the food outstanding and the support available whenever it was needed.
We were trekking during the floods in Summer 2010 in Zanskar and Changtang, and were, ultimately, the only trekking group that reached Tso Moriri during the middle of August, in the week just after the flooding. This was due to the competence of our guide, Namgyal, who changed our route to enable us to proceed, who knew exactly where to cross the swollen rivers and who kept us completely safe at all times.
On 4 occasions, Overland Escape organised Easter expeditions through the Markha Valley for relatively large school groups. This, of course, needed extraordinarily good organisation, and on each occasion, this was exactly what we got. Not only were all timings kept and all information was relevant and 100% reliable, the trekking teams Tundup organised for us, were amongst the best teams I have ever travelled with. In particular, Namgyal is in all likelihood the best guide I have ever trekked with. His knowledge of the region, its culture and wildlife is outstanding, and he is also an excellent travel companion. He can empathise with and enthuse adults and youngsters to the same degree.
Overland Escape certainly is one of the best trekking outfits I have come across in the Himalayas or indeed anywhere in the world (I have also trekked in Nepal, Tibet, Pakistan, Peru and Jordan). I would wholeheartedly recommend travelling with this organisation.
