The magic point of this region is that, close to Varzaneh dry desert, you can find Gavkhooni wetland. Gavkhooni is a preserved ecosystem, which is host of thousands of bird, migrating from north mostly. The number of the birds varies each year, depending on the rainfall of that year. In fact, the majority of wetland is dry each year. Generally, the wetland has a rich wildlife. From gees, storks, flamingos and Iranian zebras and deer to many other reptiles can be found in this area. To reach Gavkhooni, you need to take the Gavkhooni road on the east of Varzaneh for about 25 km. As a sign of your arrival to wetland, you would see a completely black mountain, simply called Black Mountain (Persian Kooh-Siah, کوه سیاه). The stones are very light, having many holes inside. The mountain is indeed the remaining of black magmas.
Built in 1100 CE. Three centuries later, in the Timurid era, it was extensively renovated. Its splendid Mihrab and all the tile designs at entrance of mosque and around the Mihrab makes the mosque a very special one in this region. You do not have to pay to visit this 600-year-old mosque. Local people say prayer here three times a day. If you do not wish to say prayer with them, wait for some minutes until people leave the mosque before you visit. The door is open from very early morning, until 1 hour after sunset. Though, if there is an occasion, including celebrations, memorial of a recently passed away local person, then mosque might be a bit occupied a couple of hours per day. If there is such an occasion, you would be listening to quite loud voice from the 20-m-high minaret, from almost all of the town. That is actually a function of Jame mosques in Persian post-Islamic age. In particular, on Friday afternoons, you could listen to the speech Imam speaking about religion and recent social, political issues. Like any other religious center around the world, from churches to temples, to enter such mosque wearing modest clothes is necessary. The dome and the minaret of the mosque are clear from almost everywhere in town, therefore it is easy to reach. It is in the centre of town.
The sand dunes are from 5-62 m high. The average height of sandy dunes are highest between deserts of Iran. It makes the landscape spectacular. There is no regular transport from Varzaneh to the desert, which is 15 km away. However, taxis would be quite cheap to take you to desert. The sand dunes usually do not move considerably, so you can camp for several nights there, having an easy access to town. However, except for late spring and summer, the temperature often drops below 10°C and to 10° below freezing in January and February), due to the lack of humidity. Thus, you would need sleeping bags if you want to camp there. The desert is about 45 km across.
