Hello! That sounds like an exciting adventure to Siberia, indeed. Here are some tips to help make your trip as smooth and enjoyable as possible.

Best Time to Visit:
The best time to visit Novosibirsk and the greater Siberia region is June through August, when temperatures are warmer. Barnaul, Gorno-Altaysk, and Belokurikha also offer beautiful autumn foliage if you aim for a September-October timeframe.

Route and Accessibility:
You can reach Novosibirsk by flight with Tolmachevo Airport being an international hub. From Novosibirsk, you can take a train or bus to Barnaul. To reach Gorno-Altaysk and Belokurikha, it's recommended to take a car or hire a taxi, as public transportation can be limited in these areas.

Accommodation and Booking:
Booking in advance is strongly suggested, especially for peak tourist season. Novosibirsk has a range of accommodations from luxury hotels to hostels. Barnaul and Gorno-Altaysk also have hotels, and Belokurikha has many well-known spa resorts.

Clothing and Essentials:
Winter clothing is a must if you're visiting in the colder months. Don't forget your warm coats, insulated leggings, gloves, scarves, and comfortable walking shoes. In summer, carry breathable, layered clothing. Also pack a good sunscreen, bug spray, and a reusable water bottle.

Health and Safety:
Russia is generally safe, but it's advisable to avoid unlit and less crowded areas at night. Be aware of pickpockets in crowded places. Emergency medical care can be limited in rural regions, so ensure you have adequate travel insurance that covers medical evacuation.

Local Etiquette and Respect:
Russians are known for their hospitality. Handshakes are common, but only take place indoors because it's believed shaking hands over a threshold brings bad luck. Russian language is spoken widely, and even a small effort to speak it is greatly appreciated by locals.
