I came across a tour to Italian Süd Tirol and I might as well take it. But I wonder what is there worth seeing besides the Dolomites? Has anyone been there? Is it really nice? Is it an expensive region? What is the average meal price? How is the weather in mid-august? Although it is in Italy it was an area that belonged to Austria. Is it more Austrian that Italian? How are the people in this region?
Haven't been for years and years, but Meran (Merano) and Bozen (Bolzano) are both very pretty towns.
Weather should be warm in the summer (70+F), but there is always a chance of a quick thunderstorm, and it can be cooler in the evenings.
The area is definitely worth a visit. Dolomites offer amazing views and panoramas. If you like trekking, climbing, that's THE place for sure.
Then, as for cities, Merano and Bolzano are very nice and elegant, but then also Bressanone, Dobbiaco, Selva di Val Gardena, Cortina (actually, this one is in Veneto but very close to Alto Adige - Sud Tirol) are worth a visit.
The region gives you the impression to be in Austria more than in Italy, becuase people speak mainly German.
Everything is clean, in order... It's a bit expensive, because it is generally a rich region.
As for weather, August is ***usually*** a nice and warm period, but you are in the mountains, so be also ready for thunderstorms and small rains...
I'd go for the tour...
If the Dolomites are not a must-been for you, you could consider the Iulian alps in western Slovenia (south of Villach, Austria) as a sound alternative. Very nice nature, friendly people (who often speak foreign languages properly), and ... lower prices than in northern Italy.
The weather conditions Amadei describes for the Dolomites also apply to this area. Hope I haven't made things more difficult for you, just wanted to help.
I was in the city where you come from, Sao Paulo, earlier this Spring.
What a huge (16 million inhabs?!) lively city!
