Surely! Siberian cities like Novosibirsk, Omsk, Tomsk, Krasnoyarsk, and Irkutsk offer a uniquely Russian experience. Here are some travel tips to make your journey enjoyable and comfortable:

Best Time to Visit:
The best time to visit Siberia is during summer, from June to August, when the weather is relatively warm and dry. If you enjoy winter sports, you can also plan to visit from December to February.

Route and Accessibility:
Air travel is the most advisable mode for getting to Siberia. Each of these cities has its own airport and is well-connected with regular flights from Moscow. Trans-Siberian railways also connect these cities.

Altitude and Acclimatization:
Altitude is not a concern in these cities as they are situated on relatively flat terrain. However, it's always good to allow a day or two to adjust to the new climatic conditions.

Accommodation and Booking:
All these cities have plenty of hotels ranging from budget to luxury. Booking in advance is advisable, especially during the peak tourist season in summer.

Clothing and Essentials:
Siberia is notorious for its harsh winters. If visiting in winter, pack adequate thermal clothing, insulated boots, gloves, and hats. If you visit in summer, lighter but still covering clothes would be suitable, with temperatures ranging from 10 to 30 degrees Celsius.

Health and Safety:
Stay hydrated and wear appropriate clothing for the weather. Also, consider getting insurance that covers travel in Russia.

Local Etiquette and Respect:
Russians place a high value on respect and tradition in public spaces, dress modestly while visiting local places and religious sites.

Lastly, try to learn a few Russian phrases, as English isn't widely spoken outside of tourist areas.
