Sierra Madre (Luzon): I look for a local guide. help! ✈️

Hi, I'd like to visit the Sierra Madre in Luzon and to visit some native peoples. Do you know an email of some local guides there? I need some emails please. Even I need also some emails of Resorts there because they can suggest me some local guides.
Thanks.

You should specify where exactly you want to go cos sierra madre spans more than 300 km and diferent provinces.

I'm sorry, you are right but I don't know where Agta or Aeta peoples are precisely but I think in Isabela province.

Hi,
I move your message to the english speaking forum.

Regards.
