Excellent video! I am currently planning a birding trip to Sabah and your video just got me too excited for it! 😅 I would be interested in the contact information of the guides you hired for the trip if you do not mind sharing.
Now you need a permit to enter. For other forest reserve like Panti, Bukit Wang, we take from Perlihitan. For Perdik we have not tried to go after they put these restrictions.
