Day trip with me to Vilnius or Jumla Beach? (Riga)

Hello locals and fellow ex pats/travelers!
I'm an American that will be in Riga for the next few days. i am thinking on moving to Riga permanently in the next couple of months. It would be infinitely more worthwhile if I can meet people. I am planning on doing a couple of day trips to either Vilnius, Lithuania and/or Jumla Beach. Send me a personal message so I don't miss it. Can't wait!

Cheers-Mat
