PinoyMountaineer Difficulty Scale (2009)

PinoyMountaineer recommends the classification of Philippine mountains according to difficulty with a numeric scale of 1-9 with the purpose of guiding enabling hikers to prepare accordingly. There are limitations to the criteria, and the PULAG factors listed below will try to account for some of these. The Difficulty scale is subject to continuous re-evaluation.

DISCLAIMER: Even though I am making this attempt to objectify the scale, I am aware that rating a mountain's difficulty is inherently subjective; the actual experience of difficulty depends on the situation (i.e. season, weather) and individual factors. This scale is meant only as a guide and cannot be the sole basis of an evaluating a mountain.

*The PULAG factors add +1 to the difficulty of the trek:
P- Precipitation > 50% of trek time
U- Unestablished trail or flooded trails requiring water-crossing
L- Low temperature; <> 35 C)
A- Animals or wildlife that interfere with trek (i.e. hyperlimatik)
G- Gusts of wind reaching >50kph
