"We rolled in our circus carriage on an old fallow meadow and founded a café in the French country house style. Apples in all their forms are the theme and at Emil's Backe we serve Trosa's most delicious tarte aux fries and the best café in Vienna!" (Source: www.tartetatin.se) A really great café where a stop is 100% worthwhile.

The river Trosaån crosses the town of Trosa here, in the historic province of Södermanland. The city is the capital of the municipality of the same name. You can use the very idyllic path along the river to the mouth of the Baltic Sea for a break, perhaps with an ice cream or coffee and cake. Trosa is also known as the "end of the world", although the origin of this epithet is unclear.
