I have a friend starting up his own eco-tourism business, in partnership with local governments in Quezon Province (northeast of Manila) - and here are the details of his next packaged trip scheduled for the 11th and 12th of June:
Event - OFFTRACK 3.0 by OFFTRACK PHILIPPINES (look them up on Facebook)
Place - Baluti Island, northern Quezon Province
Activities (all optional) - hiking, rafting, kayaking, canoeing, boating, snorkelling, fishing, and typical beach pursuits like swimming, drinking/partying, barbecuing, karaoke, and just chilling with other people.
Price - P2,000 covering transportation, accommodation (tents), group excursions, and activities available at the place we're staying in Real, Quezon.

Let me know if you're available for or interested in the trip - it won't be a 5-star luxury excursion, but I'm sure you'll enjoy it. :) (you can also share this invitation with friends, of course!)
