A nice place to do some walking and/or birdwatching is at hageven in Neerpelt.
There are walks from up to 8km and the indications or good.
Some of the walks pass through Holland as well.
When you want a nice night out in Neerpelt you should start off with a game of pool in Maxx. Afterwards you can go to the street in wich the Compromis, De Tap and Drempel are located. The 3 best cafe's in Neerpelt. Here you can keep going untill about 3 PM. After that you can either go to your accomodation or hit up a night shop if you want to keep the alcohol flowing.
Dress Code: Not really a dress code but if you want to meet somebody you better come well dressed.
If you are traveling to Neerpelt I suggest you stay away from the canal by night. Nice for a bike ride by day but that all changes by night. That is when the shady characters come out. There are rumours of dealing etc around there by night so just a friendly heads up to avoid that area by night.
