Hiking @ Penrissen area

[kuching]

Dec 5, 2008. It was a bad idea to hike in the muddy trail during the rainy season, but it was really fun for exploring in a new location. We found a milky white coloured river which the water contains dissolved calcium carbonate.

It's also a surveying trip because I will be back to climb the limestone hill to search for Nepenthes northiana (pitcher plant which was thought to be as endemic species to Bau area only in the past) and others flora & fauna.
