The natural wonder known as Green Canyon is located 30km northwest of the beach resort of Pangandaran. The canyon is a narrow gorge, formed by a river cutting through soft limestone rocks. The edges rise up to 20m above the water, always casting a shadow so the gorge stays cool the whole day. Green moss covers the rocks hence the name "Green Canyon." Close to the end, when it becomes to narrow for the vessels to pass, is the most beautiful spot: a natural limestone bridge spans the gorge and stalactites are hanging from the ceiling, dripping with water. You can take a refreshing dip in the water too, and jump of the rocks into the water.
The easiest way to come here is to book a trip in Pangandaran. Normally your guesthouse should be able to book you one for not more than 100,000 Rp per person (€10) or check with the travel agents around the beach. Normally this will be a day trip with a minibus. They will probably pick you up ath your guesthouse early in the morning, but be sure to check this. Normally they will first bring you to a few '"factories" first. We went to a krupuk factory first (krupuk is a salty crispy shrimp biscuit, tasting a little bit like crisps) and afterwards to a man who carved wayang kulit puppets from wood. Of course the people asked if we didn't want to buy anything, but they were not persistent, only a little disappointed, if you don't buy anything.
Next stop was a small kampong (Indonesian village) with bamboo houses and a long bamboo bridge spanning a river. Don't pay at the bridge because the villagers told us you should only pay when you cross the bridge with a bicycle or motorbike. You can jump of the bridge to take a swim in the river, as the water is rather clean. Our tour brought us to a small port afterwards, with nicely light blue painted motorboats, floating on two large bamboo trunks, one on each side. From here the boats sail to the canyon to see this remarkable natural feature. There is also some nice rain forest and village scenery on the way.
