If as a vehicle you will choose the car, it can give you a lot of advantages. The most important thing is the possibility of independent choice of the route of travel. By the way, it is better to develop it in advance. Explore the map of the Altai Republic on the Internet, read reviews of local attractions, select the ones that you like and develop your own itinerary. Note that if you use not only the central routes, but also small roads, their quality can be quite critical. Be prepared for the fact that before many wonderful places (waterfalls, passes, lakes) can not be reached by car, so you will have to use the services of guides. But there will not be any problems with this, at every step you will find suggestions for excursions and all kinds of entertainment.
For recreation in the Altai Republic you can use not only your own car. In recent years, tourism in the republic has been developing at a rapid pace, so that a large number of various recreation centers are available for the choice of visitors. You can buy a ticket, which will include travel by bus to and from the place, accommodation at the base, meals, a variety of excursions.
If wild rest in the tent does not suit as well as life at the base, then you can rent a separate house or room. But keep in mind that if your trip is planned for the weekend, then it's worth taking care of housing in advance.
The Altai Republic will welcome you cordially, but this is in case you have a rest in touristy developed places. If you dare to travel to more "wild" places, where tourism is not so developed, then it is worth sticking to some simple precautions. For such a trip, it is better to gather a friendly and not small company. Traveling alone is quite dangerous. Take care and about any means of self-defense. It is better to have with you a stock of the most necessary products and medicines. In the remote villages of shops quite a bit and they close early. For the night it's better to stop in specially designated places (camping), there you can rent a house or stay with a tent.
Consider the characteristics of your body. Pressure and climatic conditions are quite different from those in the plains. The climate in the Altai Republic is mild and quite warm. In summer you will be pleased with the hot sun and moderate humidity. Winter is also not characterized by severe frosts and large snows. In some years in certain areas of snow may not be at all.
It is not for nothing that Altai was called "pearl Siberia" ... Whatever sights and which route you would choose the mountains will surely give you rich impressions. But be careful! Because, one who visited Altai once, can not not return here again.
