Scenic Panemunė road which traces Nemunas river valley at its northern bank and connects Kaunas to Šilutė. Beyond Šilutė the road continues to Klaipėda therefore making the Panemunė road a slower yet more interesting alternative for Kaunas-Klaipėda or Vilnius-Klaipėda route by car.
The road is famous for its castles and manors that can be visited en-route. These buildings were used as opulent residences rather than defensive structures but their impressive towers and strong walls may be decptive. Only a couple kilometers from Kaunas limits is Raudondvaris with its castle-like red brick manor, built in 16th-17th centuries.
Further on you will pass Raudonė, a castle with a 33,5 m fairy-tale like gothic tower now used as a school. It was originally bult in late 16th century and rebuilt after suffering heavy damage in World War 2.
Finally there is the Rennaisance Panemunė castle. Dating to 1604 it now houses a museum and you may climb its mighty towers. The castle its being restored, the surrounding park still providing a nice stroll even after heavy damages done by Soviets.
There are other things to see on the Panemunė road. The scenery is nice and the surrounding towns are pretty. The towns in the Nemunas valley closer to Kaunas, such as Vilkija, are built on several terraces.
In the western reaches of the road (beyond Skirsnemunė) you enter Lithuania Minor. These areas were once ruled by the Germans and this is still visible in architecture. The largest town in the area is Šilutė, where you can make a detour to Nemunas delta if the approach roads are not submerged by the waters of Nemunas river (as happens every spring, but you may use a special tractor ferry).
By the way the Skirsnemuniškiai town that you pass here is famous for having the longest name among the Lithuanian single-word placenames (16 letters).
