If you are looking for the fastest way to get to Lake Baikal from Irkutsk by bike, your only possibility is the direct route parallel to the river Angara leading you to Lisvyanka 70 km away. The road is in perfect condition for Russian circumstances, but it is characterised by dozens of ascents and descents (flat parts are completely missing). It is true that they all are not excessively long, but because of the heavy and frequent ascents they require a certain sportiness of the rider.
