How to Get to Lake Onega
The usual access point for Lake Onega is the city of Petrozavodsk on the lake’s western shore. Petrozavodsk is served by overnight and daytime trains from Moscow and St. Petersburg and by scheduled flights to Petrozavodsk Airport; the city’s harbor has passenger services onto the lake.
From Petrozavodsk’s riverfront/harbour you can catch hydrofoils and motor boats to islands and sites on Lake Onega (for example services to Kizhi Island). Local travel on the lake is by scheduled boat/hydrofoil in the summer season.
Tips for Visiting Lake Onega
- Use Petrozavodsk as your primary gateway-most passenger boats and hydrofoils to islands (including Kizhi) depart from Petrozavodsk's piers during the navigation season (roughly June-August).
- Book scheduled boat or hydrofoil trips in advance and check timetables carefully-services are seasonal and can be limited; arriving without a reserved seat often means waiting for the next crossing.
- Plan island-hopping or shoreline cruises early in the day to enjoy calmer waters and quieter bays; many travelers only visit the famous open-air museums and miss the smaller monasteries, promontories and sheltered inlets around the lake.
