The trek was wonderful - especially the small group size and the fact that our trail was different from other groups made it a very beautiful and private experience.
The whole team was great, the guide took care of every issue and the food was very delicious - the tea in the morning was the best way to get up. Sleeping next to the glacier, seeing the milkyway, the hike to the lake on the second day, walking trough the forest and doing ziplining were my highlights.
The 4. day could be organized better in advance (hostel reservation etc.) but all in all an experience for a lifetime. Thumbs up for the guide!.
