Arshan (Baikal): The Guided Tour to the Sun Observatory and Extinct Volcanoes
Русская версия We are very far from being the fans of organized tours, especially after some unpleasant experiences, for instance, in Abkhazia and Zanzibar. This negative experiences, however, may be contested by the positive ones, such as tours in Kamchatka or Olkhon Island in Baikal. Similarly, the guided tour to Arshan (we walked around it on our own a lot too) also left us with great impressions we are going to share with you.
The 3-4 hour guided tour to the sun observatory and extinct volcanoes takes place in Tunkinskaya Valley which received its name from the river Tunka (translated as “dark water”). Tunkinskaya Valley is well known for its unique nature: a traveler may find very old trees (for instance, a 500-year-old larch), rocks (marble, limestone) and extinct volcanoes (Kovrizhka is considered to be the oldest one; the youngest one erupted 20000 years ago). Tunkinskaya Valley is 67% of forest, mainly conifers. The Valley lies in the embrace of the two mountain ranges: the Sayan Mountains in the north and Chamar-Daban in the south (the latter is also called Siberian jungles). From the east and west the Valley is limited with lakes Baikal and Khövsgöl. In 1991, the Valley received the status of the national park.
From the guided tour, we learned a lot about the colonization of Siberia and Tunkinskaya Valley in particular in the 17th century, mainly by Cossacks who received large plots of land and quite some money for settling here from Tsar. Little wonder that Cossacks did not welcome the Soviet power and were violently persecuted for this.
The guide told a lot about the local traditions, for instance, about the offerings to the local spirits at the special places on the road. We also stopped by one of such places.
Finally, we reached the sun observatory officially named Tunkinskaya Radiophysical Observatory. This is one of the leading institutes of the Russian Academy of Sciences; it was founded in 1966. This particular place was chosen because of its high level below the sea and because this is one of the few places with the highest number of sunny days yearly. The size of this territory and its equipment is indeed impressive. 265 antennas keep buzzing: this is how the observatory works.
The radiophysical observatory
is open for visitors unlike the neighboring Radioastronomic Observatory Badary. Yet, the major object of the latter is very visible despite the fence. Also, unlike the radiophysical observatory which was being bult for 16 years, the Badary antenna (which is actually the very-long-baseline interferometer) was being built for three years only. The antenna weighs 900 tones, it is as tall as a 12-storey building and its diameter is 32 meters. The antenna receives the signals from the objects in cosmos which may be as far as 100 million light-years. With the help of these signals, scholars decipher the weight of the object, its chemical composition, and radiation.
Having seen the human creations, we went back to the natural creations – volcanoes. To visit them, we had to get stuck in the mud after the rain.
We really recommend this guided tour (we bought it from Discoverytour and enjoyed the guidance of Irina Kolmykova).
After the tour, guide Irina invited us to the sanatorium to see the documentary about Tunkinskaya Valley and Baikal and then we walked home through Arshan, stopping by to eat khushury, of course.
The next day we went to Irkutsk in which we discovered a very unpleasant surprise.

Olkhon Island (Baikal): How to Reach It, Where to Stay, and What to Do
Our constant readers remember that Olkhon island became one of our greatest impressions from Baikal. Today we tell how to organize the trip to the island as effectively as possible to fully enjoy it. In summer, you may reach Olkhon island by the ships from Irkutsk to Ust-Barguzin and Irkutsk to Severobajkalsk both stopping at Olkhon. Yet, this possibility may be less interesting for the budget travelers because of the high cost of the ticket.
Tolbachik Volcano (Kamchatka). Part 3: After the Eruptions
Ascending Tolbachik volcano, we saw the consequences of its eruption – the hardened lava fields at its foot. Yet, despite the widespread opinion, a volcano eruption is not just the lava flowing out of the crater. The eruption may be seen and heard hundreds of kilometres beyond the crater, in the most unexpected places and not only in the form of lava..
Baku side trips: Gobustan and mud volcanoes
Early in the morning, we departed from Baku where we spent our first day in Azerbaijan for Gobustan to see a Unesco World Heritage Site – national park famous for its Rock Art and nearby mud volcanoes. First you have to reach the bus station at the 20th of January str. (by marshrutka nr. 29). Then take a bus to Gobustan and ask the bus driver to stop you there; this trip takes less than an hour.
