Today we drive to Murgab (approximately 6–7 hours). First, after breakfast, drive the 50 kilometres from Sary Tash to the Kyzyl Art Pass (4280 m). In this spectacularly remote spot, you will cross the border from Kyrgyzstan to Tajikistan. Remember to be patient as officials work through the various permits and procedures. Once inside Tajikistan, you'll make your way down the 95 km to Karakul Lake for lunch, with yet more dramatic scenery and photo opportunities along the way. Karakul Lake is too high to support aquatic life and is the largest out of 800 lakes in the Pamirs; these lakes were created by earthquakes, tectonic activity and glaciers. The final 135 km today takes you to Murgab via the Ak-Baital Pass (4655 m), the highest pass on the Pamir Highway and in the former Soviet Union. Murgab is located in a valley at approximately 3000 m above sea level, surrounded by high peaks. This region is inhabited mainly by Kyrgyz people. From here, on a clear day, you can see Muztag Ata (7546 m), the highest mountain in the Pamirs. While here, your hosts will prepare you a simple dinner and breakfast – homemade bread, plov (rice pilaf) and fried eggs or porridge. Keen stargazers will be treated to a great display on a clear night, with very little light pollution affecting views of the night sky. (B/L/D)
