With the Tallinn Card, you get unlimited access to public transport within city limits. For visits to close-range attractions, take advantage of your free three-hour bike rental from City Bike. To explore places located further from the city centre, grab a Tuul electric scooter, one of the most environmentally-friendly modes of transport out there. All you need is the Tuul app, which you can easily download from the web. Kalamaja and Pirita are especially bike-friendly areas with gorgeous sea views.
