Bordering France and set largely in the Rhineland region of Germany, the Palatinate Forest Nature Park is the largest contiguous expanse of forest in the country, which, as you'd rightly assume, makes for a lot of nature exploration.
Made up of low-lying hills cut by numerous rivers and undergirded by sandstone and volcanic rock, you could access this massive nature area from Stuttgart in an hour and a half or choose to stay within the park jurisdiction in towns like Kaiserslautern, Landau, and Weiden. Why not? The forest will be right at your doorstep.
The best way to explore the area may be through tackling a stretch of the Goldsteig , a 660 km (410 mile) hiking trail that delves through the Upper Palatinate and continues into the Bavarian forest. Considered one of the foremost hiking tracks in the country, the path may actually start or end in Marktredwitz and lead either north toward Passau or nearly all the way to Zugspitze in the south. If you prefer life atop two wheels and barreling down a mountainside, then the huge network of routes from Schopp to Lambrecht are going to be key in making your next adventure a success. Then again, something like the Seven Castle Tour provides a day of walking that starts and ends in Schönau and stuffs magnificent panoramas and 800 year old ruins in between. For more on the bevy of trails to be accessed from anywhere in the park, check out the included links.
Note:If you're one to value your sophisticated beverages above your nature wayfaring, then be sure to check out the numerous stops on the German Wine Road. It's the oldest wine route in the country, starting at the French border in Schweigen-Rechtenbach and terminating at the town of Bockenheim an der Weinstrasse. The area is known particularly for its dry red wines.
