The best hiking is in the northern parts of the province. Even the Germans, who rush to the Bavarian Alps, often overlook the some 25,000 hiking trails in Franconia. Local tourist officials have details of the best hikes in the area. Most trails are found in Germany's largest park, Altmühltal Nature Park, and in the Frankenwald.
You can also explore Franconia by bike. At all area train stations, you can rent a mountain bike for 10€ per day, half-price with a valid train ticket. Local tourist offices have information on the best biking routes. The Danube Bicycle Path cuts right through Regensburg; cyclists can ride along its 650km (400 miles) from the river's source to Passau. The Regensburg tourist office is the best source when you're organizing a biking trip. You can even go as far as Vienna. The Five Rivers Bicycle Path is a 3- to 5-day circular route through the valleys of the Danube, Naab, and Vils. This path links Regensburg with Amberg and Nürnberg.
