Honestly, I only find out about this on Pinoy Big Brother Teen Edition Plus when the teens went to Puerto Princesa Subterranean River National Park for their island adventure. PPSRNP is currently on the top 10 list of the New 7 Wonders of the World. Tubattaha Reef and Chocolate Hills landed on top 6 and 7 respectively. While Mayon Volcano is struggling at number 16. These are our country’s pride. Please take part and make Philippines known for its wonderful nature! Just log in at www.new7wonders.com.
