Fishing! This is a region full of beautiful rivers and every village and town seem to have a shop selling fishing tackle. Two interesting links I have found are both in Czech only though so you may need google translate - or let us organize this for you and we will point you in the right direction! http://www.mrk.cz/rybarske-reviry.php?id=2843 and http://www.rybarifrydlantno.cz/u-vody-s-rybarem
Lysa Hora, the highest ,mountain in this area, is 1324m high and in winter many people climb up it to ski down it after a bowl of soup and a beer or a hot wine. Stunning views and it's pretty to look at from afar.
This link will take you to a top ten highlights of Ostrava in German. A blog made by fellow world traveller. Quite honestly I think their top ten is very well put together. The Svet Techniky comes highly recommended though their website certainly doesn't portray just how interesting and fun this place is for adults and children alike.
