Roavina is a free worldwide travel guide and self-guided itinerary planner that covers 110 cities. It is built entirely from open data and does not offer any bookings, tours, or items for sale. The tool is designed to help travelers plan their own trips without needing an account or relying on a commercial service. Its primary function is to generate a deterministic itinerary based on user inputs, meaning that the same answers always produce the same plan, with no random or generated elements. The planner operates on a set of clear rules. A stop is never scheduled while its place is closed, so the itinerary respects opening hours. Each day is constrained to its own time window, accounting for travel time and breaks. Users can plan their trip hour by hour, explore a deep catalogue of attractions across cities, and adjust their plans around seasonal events such as Oktoberfest or specific landmarks like Central Park, Kew Gardens, or Schönbrunn Palace. The interface is straightforward: visitors select their preferences and receive a structured day plan. Typical use cases include independent travelers who want to build a custom itinerary without commercial influence, or those who wish to explore a city’s offerings based on open data. The workflow involves choosing a city, setting a day window, and selecting points of interest. The planner then outputs a schedule that fits within the given constraints. No registration or personal data is required. Technically, Roavina relies on open data sources for its content, including photographs licensed under Creative Commons. The site is accessible at roavina.com and does not require any special software or plugins. It is a straightforward, rule based tool for self guided trip planning.
