The tripto catalogue lists 12 nature parks, biosphere reserves and natural landscapes – river landscapes, forests, orchard country and long-distance trails. Entry is usually free.
The Spreewald is a UNESCO biosphere reserve with more than 970 km of waterways; the best way to explore it is by punt from Lübbenau, an hour from Berlin. The Altes Land on the Elbe is northern Europe's largest fruit-growing region, with half-timbered houses and a fruit route – especially popular during the spring blossom. The Bode Gorge between Thale and Treseburg is a deep granite gorge in the Harz and a classic hike, free to access. The Ivenack Oaks near Stavenhagen were Germany's first National Natural Monument, with a treetop walk and fallow deer in the wood pasture. Dresden Heath offers about 50 km² of forest right on the edge of the city, and the Harz Witches' Trail runs about 100 km from Osterode over the Brocken to Thale.
The catalogue's places are spread across many states: three in Lower Saxony, two in Saxony, and the rest one each in Brandenburg, Saxony-Anhalt, Mecklenburg-Western Pomerania and other states.
In practice: allow half a day to a full day, and several stages for long-distance trails such as the Eifelsteig or the Witches' Trail. Costs usually only apply to punt trips, treetop walks and parking – €3 a day at the Bode Gorge. The best time is spring to autumn: blossom in the Altes Land in April and May, punt trips in the Spreewald mainly in summer.
