UNESCO World Heritage

How much of the UNESCO World Heritage have you explored?

The United Nations Educational, Scientific and Cultural Organization (UNESCO) seeks to encourage the identification, protection and preservation of cultural and natural heritage around the world considered to be of outstanding value to humanity.

Five spots are identified from the Philippines:

1 Baroque Churches of the Philippines (1993)
2 Tubbataha Reef Marine Park (1993)
3 Rice Terraces of the Philippine Cordilleras (1995)
4 Historic Town of Vigan (1999)
5 Puerto-Princesa Subterranean River National Park (1999)

I've only been to one, the Rice Terraces in Batad and Banaue. I've been wanting to go diving in Tubbataha but I guess I'm not yet skilled enough to go there. I thought Calauit Island Game Reserve is listed but apparently it's not.

I somehow equate the identified sites of UNESCO World Heritage as a must see travel places. I regret why I passed the chance to see the Pyramids of Egypt!

As I browse through the list, I've been to more UNESCO World Heritage sites than I thought:

1 Summer Palace, an Imperial Garden in Beijing, China
2 Yungang Grottoes, China
3 Imperial Tombs of the Ming and Qing Dynasties, China
4 The Great Wall, China
5 Mont-Saint-Michel and its Bay, France
6 Vatican City, Holy See
7 Temple of Heaven: an Imperial Sacrificial Altar in Beijing
8 Palace and Park of Fontainebleau, France
9 Cathedral of Notre-Dame, France
10 Historic Centre of Avignon: Papal Palace, Episcopal Ensemble and Avignon Bridge, France
11 Church and Dominican Convent of Santa Maria delle Grazie with "The Last Supper" by Leonardo da Vinci, Italy
12 Piazza del Duomo, Pisa, Italy
13 Historic Centre of Florence, Italy
14 Venice and its Lagoon, Italy
15 Cinque Terre, Italy
16 Works of Antoni Gaudí, Spain
17 Historic City of Ayutthaya, Thailand
18 Statue of Liberty, USA
19 Historic Centre of Macao, China
20 Canadian Rocky Mountain Parks, Canada
21 Palace and Park of Versailles, France
22 Roman Theatre and its Surroundings and the "Triumphal Arch" of Orange
23 The Loire Valley

To add to my must see sites before I die:
1 Taj Mahal, India
2 Jiuzhaigou Valley Scenic and Historic Interest Area, China
3 Tubbataha Reef Marine Park, Philippines
4 Halong Bay, Vietnam
5 Angkor Wat, Cambodia
6 Stonehenge, Avebury and Associated Sites, UK
7 Grand Canyon National Park, USA
8 Pyramids of Egypt

But why am I looking at the list? With too much work at hand, I can't seem to focus on what I'll do first, I can't even clear the clutter on my table, I can't stop thinking about the long holidays that is coming up.

I somehow came up with the idea of a 6 day trip to cruise Halong Bay in Vietnam and see Angkor Wat in Cambodia. As I googled, looks like 6 days isn't enough, uh oh. Won't this be anti-climatic for a follow on trip to Coron, Palawan? Hmm...If you have any tips, do drop me a line. :D
