Read full description

Discover Sofia one stop at a time. Sofia Subway Map brings transport maps, station information, an offline route planner and a practical city guide together, helping you prepare the journey and enjoy the destination. YOUR SOFIA TRANSPORT MAP Explore the city on an interactive map. Find stations, follow colour-coded lines and see how different parts of the network connect. Switch from the big picture to the details of a line or station, then return to the map when you need your bearings. Keep Metro, tram and bus information close as you plan a day around the city centre or your next neighbourhood. PLAN BEFORE YOU GO Choose your starting station and destination in the built-in route planner. Review a suggested journey, its stops and connections before setting out. The planner uses information stored in the app, so you can prepare supported routes without an internet connection. Journey durations are estimates calculated by the planner; they are not live departures or guaranteed travel times. STATIONS AND CONNECTIONS Open individual station cards and browse stations along a selected line. Get a clearer picture of your journey before reaching the platform. Use the map to understand where you are heading and the line list to explore the network at your own pace. Whether you are visiting for a weekend or organising a familiar trip, the same tools help you keep the next step in view. A GUIDE BEYOND THE PLATFORM Explore the station-based city guide for ideas around your next stop. Discover places to visit and make transport part of your plan for the day. Start with a station, look at nearby points of interest and choose what you would like to explore. Keep the practical journey and the interesting destination in one app. ARRIVING IN SOFIA Browse Sofia airport information and transport guidance as you prepare the first part of your visit. Airport boards and connected travel services depend on their external data sources. Check the relevant operator or airport for the latest departures, disruptions, access requirements and fares. TOOLS FOR A DAY IN THE CITY Check local weather and time, browse price guidance and find information about food, shopping, safety and travel rules. Use these tools to prepare for the conditions, organise your day and decide what to explore next. Reference prices and travel guidance provide context; they do not replace current offers, official advice or professional guidance. FROM THE FIRST STOP TO THE LAST Prepare a route before leaving, consult the map when you arrive and open the guide when you are ready to explore. A focused collection of transport and travel tools keeps useful information together on iPhone and iPad. Choose the screen that suits your planning, from a quick station check on your phone to browsing the network on a larger display. IMPORTANT TRAVEL INFORMATION Online map tiles, weather, airport boards, external links and connected services require internet access. Data availability and service coverage vary. Some guide content or features may require viewing an advertisement. Always check current transport operations, fares, opening hours and important travel requirements with official sources before relying on them. Sofia Subway Map is an independent travel app. It is not affiliated with Metropolitan Sofia, Sofia Urban Mobility Centre or airport operators.
