I have been there a few times and think it well worth the visit..very interesting. Even the museum across from it is worth seeing...a nice walk from Tallin center.
IT REALLY IS A TRIBUTE TO TALLINN AND ESTONIA..MEMORADBLE PALACE ,BEAUTIFUL GARDENS,SWAN POND IS RELAXING..THE SMALL INDOOR AND OUT DOOR CAFE IN THE GARDENS..SERVICE, EXCELLANT CAKES AND COFFE..THEIR STAFF ARE WELCOMING AND PLEASENT IN THE WHOLE COMPLEX..IT IS A ""MUST ""WHEN YOU VISIT TALLINN..
Kadriorg is, next to the KUMU, one of the most interesting museums in Tallinn. Next to the exhibitions, the Kadriorg Palace itself is worth a visit!! absolutely recommendable.
