…around Baikal there is really no reason to panic. And if you are in a city or village, local people will be happy to give you directions when you ask them (through an electronic translator on your phone). In most large cities and other popular tourist stops you will find displays with maps that are marked: "You are here!" In Irkutsk there is even a pedestrian route called the "Green Line." If you see this line on a street, simply follow it, and it will lead you to a convenient road map.
As a rule, in almost all of our towns and villages around Baikal you will find good connection to the internet. Any navigator app should identify your exact location on your phone. When you check into your hotel, be sure to take one of the hotel cards with the street address. Or at least remember the name of your hotel, so that you can ask for directions.
If for some reason you get separated from your group during a tour, then try to text or somehow connect with your guide to provide them with your location data. And if you are going out on a trail, or into the wild, be sure to download a local map first (through
maps.me), or bring a paper map with you. Always carry your tour guides' phone numbers with you, as well as contact information for your hotel, or an emergency number for the national park that you are visiting.
