The Annapurna undoubtedly provides some of the world's best trekking routes, including as it does a greater variety of scenery and culture than can be found in any other comparable area. The route via Tilicho Lake and the two passes (Mesokanto La 5099m and Tilicho Pass 5230m) that guard it from the Kaligandaki Valley beyond is still used and offers the adventurous and fit trekker high mountain scenery at its very best. Mesokanto La is low altitude pass than Tilicho but more technical and need to be use rope. With same timeframe you can also attempt the Tilicho pass.
