I would hate to have the people behind that website organizing my travel and tours . . . I clicked on the Mindanao map and ended up in Palawan . . . Palawan is part of MIMAROPA (MIndoro, MArinduque, ROmblon, PAlawan) . . . a couple of hundred miles from Mindanao
A better website is http://www.allsportsphilippines.com
especially if you are seeking outdoor sports activities.
Or, if Mindanao is where you are headed, then try http://www.travel-davao.com
for caving, white water rafting, wakebaording, scuba, snorkeling, cayoneering, island hopping, mountain trekking and cultural immersion with indigenous peoples.
Seriously, it is more fun in the Philippines
