Istanbul has nearly 250 picturesque cycling routes and 12 courses winding across the two continents, along with historical city landmarks, the Bosphorus, the Golden Horn, and the Marmara Sea coastline. Sightseeing on two wheels promises much more fun than mere walking and needless to say, it saves you precious time. Princes' Islands and Belgrade forest, just 15 km from Istanbul, promise cool bike adventures. Mud-biking is a special choice for extreme riders available in Belgrade forest during the rainy spring months. The biking season lasts from April to October, yet, on request, it is available year-round.
