Berlin’s 330 trails helped it land in first place, with many routes having relatively gentle terrain and less than 150 metres of elevation gain.The Havel Heights Trail is a top choice for those wanting to escape the busier streets without leaving the city. The 7.5-mile route winds through Grunewald Forest along the high banks of the Havel River, offering views across the water.For a walk steeped in history, visitors can explore a central section of the Berlin Wall Trail. The wider route stretches for more than 99 miles, but a section of around nine miles combines historical landmarks with the city’s modern street culture. The Bernauer Straße Memorial, which includes preserved sections of the former border and an outdoor exhibition, is another highlight.The Panke River Walk offers a different perspective, taking walkers through gardens and public parks in northern Berlin. Vienna came second with 250 trails and an average rating of 4.7 out of five. The Austrian capital has 12 official city hiking trails, many of which are accessible by public transport.
