Map..how to get there
easy from Porto Alegre by Bus via Novo Hamburgo..
then you have the choice of 2 routes..through Morro Reuter, Inland via Santa Maria do Herval into Boa Vista do Herval..Signs will guide you..you've clocked around 110km
or, when coming from Santa Catarina, take the turn off at Novo Petropolis, follow the road..there is only one. of course you can do that also when coming from Porto Alegre I've been there, please feel free to have a look
SANTA MARIA do HERVAL
