- National Sea Museum in Klaipeda (city) - link. You'll be able to see some dolphins etc. On your walk to the actual museum (where cars are forbidden) you'll find horses with carts for rent () and the ride on them is about €1.50~. The Sea Museum costs €4 per adult.
- You should also visit a resort town Nida (German: Nidden) which is not too far away from Klaipeda. You will definitely find something to do there!
- Of course visit the capital - Vilnius and you'll find plenty of places to visit. I don't come from that city, but the first time I went there, I could find many interesting places :P
I'll update this post later, if I remember something else.
Also don't be surprised by the amount of German cars!
