Favorite destination in Estonia?

I'm headed to Estonia in May (and a few other places.)
I have friends who say that Tallinn is wonderful and walking around the old town
is a great way to enjoy the area.

Kadriorg Park, Brigit's Convent in Pirita, Toompea Castle, Alexander Nevsky Cathedral.

I would also be interested in hearing more suggestions.
Thanks

I spent a lovely week in Tallinn last Sept and felt immediately comfortable with this beautiful city; clean, easy to navigate their transit system and full of helpful people. If you visit Kadriorg then continue up the road a bit to KUMU, the modern art museum. I visited Rocca Al Mare, the outdoor living history center, and found that quite interesting. If you have time for day trips I strongly urge you to go with EstAdventures, I did Lahemaa and Western Wonders, which included the charming town of Haapsalu; seeing what was outside of Tallinn really made my trip complete. I could have spent days and days happily wandering the cobbled streets of Old Town, very impressed that they have managed to preserve it so well.

We were in Tallinn (easy ferry trip from Helsinki) a few years ago. It's a beautiful, well-preserved medieval walled town. Be sure to climb the Town Hall tower, to have a great view of the main square below and the town. The Rick Steves walking tour was very helpful. We had a delicious dinner at a Russian restaurant (sorry - don't have the name) in the market square. On Wednesday, the town square filled up with vendors selling handicrafts, etc. and with lots of tourists/shoppers who I presume came from one or more cruise ships -- it was fun and lively. We took a tram out to the Estonian Open Air Museum (pioneer village), which was quite interesting and made for a pleasant day.

We spent 3 days in Tallinn last summer and also really enjoyed the Rick Steves walking tour. There is a lookout where you can take fantastic pictures that we wouldn't have found without the tour. We had a lovely day walking to Kadriorg Park (about 25 minutes from the old town) and then crossing the street to the beach. Our favourite restaurant, and we went there twice, was Kompressor. It's an inexpensive place that serves huge stuffed pancakes. The Ham and Brie one was delicious!

Tallinn is a beautiful place with very friendly people. A sweet saleswoman explained the Estonian flag to me - black (for the earth), blue (for the sky), and white (for purity). A fairy tale place, which was under the iron rule of Germany, then the USSR. Tallinn is all of Estonia we got to see on our one-day visit on our Baltic cruise. We loved Restaurant Aed (in Rick's book) - excellent food in a pretty setting at very reasonable prices - they gave us a sample of fir shoot ice cream, which was subtle. The Estonians are big on forests and they have a decided pagan streak! Loved the place!

Thanks for the info - I will definitely be wandering around the old town area and appreciate the tips.
I'm going to look for Rick's info on Tallinn.
