The perfect first contact with Nepal. This was my first trek in Nepal, can't think in any better choice. Including few days at Katmandu and Pokhara. Trek is amazing starting at rural Nepal and moving over the mountains. I went on May, and clime was really fine.

I have now done the Philippines tour and the Thailand tour. This review is for the Philippines tour. Everything was stress free, got to see everything we wanted to. The accommodation was of a decent standard, the activities and travel was all thought out and good fun. You get a nice bit of free time too. We over the moon with our group leader Jess. She was knowledgeable, funny, organised and quality at karaoke. Jess made everything seamless. Would book a third trip with Intro!
