I've been going to Portugal in Feb' for driven boar, for the last few years, BUT, it's very hit, and miss.
I go because I spend time with my Portuguese, and Spanish friends, and whilst I'm always hopeful, my expectations have been lowered in more recent years.
To be fair, this is for club, & association hunts, which are cheap, and I know what to expect.
Most of the big driven hunts, Monteria's, will be in Spain. They can have a LOT of animals, mainly Reds, & Fallow, which a far more highly prized over there, with a % of boar, and occasionally Mouflon. But you will pay for the privilege.
Mark Curtis at A1 Decoy does a lot of these trips, and it would certainly be worth speaking to him, to see what he can offer.
Here's one trip he's doing in Feb this season, but he does them every year.
