A spa vacation awaits you in Tallinn’s Old Town along with a trek through Estonia’s natural wonders - forests, swamps, bogs and the mystical Baltic Sea. Seems too good to be true? Mission: Nature will also take you on virtual adventures where you can dive to the bottom of a primordial sea and meet creatures who lived hundreds of millions of years ago - you can’t find that at the bottom of the pool at Kalev Spa’s water park but you can test out your imagination after a visit to the museum.
