For those of you who like Trekking, you've probably planned to go to Nepal, around Annapurna at some point in your life. If not, DO IT!
On the way, definitely go for the 2 days long side track to Tilicho Lake. This lake, 5000m high is certainly on the highlights list of this 2-3 weeks long trek.
I'm not going to make a spoiler with the actual view of the lake, but even the way to get there is just gorgeous! Mind your step though!
By the way, the entire track is quite easy to follow, you definitely don't need a guide for the entire 'around Annapurna' trek. Just don't go by yourself as It is never safe to walk alone. Best season to go is either late april/may, or October/november (when I took this pic)
But that's enough with the recs, I hope you will be eager to go on this adventure, it's REALLY worth it!
