We went to Nepal on the summer of 2010 and we decided to do a trekking with Responsible Treking because we know a catalan friend of us who is working there, Daniel. The manager of the travel agency (who's like our grandfather) is called Chhewang and he recommend us to go to the Mustang part because in august it rains a lot in the low parts of mountains an also in other parts of the country, and it was true, we went for a week and it rained few only two afternoons.
You'll see very different landscapes in seven days and you'll go until 3800m (the limit high to don't have altitude problems), we think that this is also interesting.
The porters were fine and one of them could speak English very well, so we could ask whatever we want about culture and mountains.
The villages you cross are also beatiful and you can find whatever you need (sometimes perhaps too much touristy). We'd enjoyed the people, monasteries, bridges, views we foun and if you're lucky the sky will give you the present of take clouds for a moment and see the great mountains of Himalaya (early in the morning is the best time). We could see Anapurna I, Daulhagiri, Nilgiri and Machapuchare, absolutly amazing!!!!!
Si teniu pensat fer un trekking curt i facil, amb poca pluja i amb paissatge variat us recomanem aquesta opcio, aixi com l'agencia pel seu bon tracte, preu i qualitat.
