Gunung Korbu is the 2nd highest mountain in Peninsula Malaysia, just 3 meters lower than Gunung Tahan. Gunung Korbu is resting along with many other 2000m peaks along the Titiwangsa range stretching along state borders of Kelantan, Pahang and Perak.
You can climb Korbu from Tanjung Rambutan, Ipoh, Perak which takes about 2 or 3 days to reach the summit. Or consider a more challenging trek starting from Tanah Rata, Cameron Highlands, Pahang. The trek from Cameron Highlands is a traverse trek across Gunung Yong Blar (7156ft) and Gunung Gayong (7156ft), 3rd and 4th highest in Peninsula Malaysia respectively.
When reach the first camp site, there will still need 5 hours trekk to summit. Before one hour to summit the way is very steep almost 80 degree and a lot of tree root you could hold in order to climb up.
Actually when trekking along the first camp site have to take note to avoid lost in jungle. If raining season, there will have many leeches, mosquitoes and sand fly will sleep with you, well need to prepare mosquitoes coins.
