Trekking in Nepal above 3000 - 4500 meter from sea level is a moderate trek suitable for passionate walkers who have the ability to walk at least 6-7 hours a day with a light rucksack. Trekking such as hiking Kala Patthar or crossing Thorong La in Annapurna requires previous hiking and trekking experience. In some days we might even need to walk for 7 to 8 hours. Walking in higher altitudes is actually more challenging than walking in the lower altitudes; however, if you are in excellent health condition with moderate body fitness, have a positive attitude and strong willpower, we can complete the trek successfully. Exercising and jogging regularly is good idea to develop your strength and firmness. Past hiking experience would be an asset but no technical skill is required for this trip. Member with pre-existing medical conditions such as heart, lung, and blood diseases should inform Guide in Himalaya before booking the trek. We also recommend that you consult your doctor(s) before the trip plan.
