Legend Available info - Trailhead - More Info - Trail News Trail Trail name - Sometimes trails are known by various names. Therefore, the names used here follow this priority: 1) most widely known or commonly used, 2) official name (if any), 3) geographical name. Use the site search box if you don't see the trail you're looking for here. NOTE: For listing purposes, the "puu" has been left off trail names as applicable. Distance Length - This is the real distance, in one direction, of the trail from trailhead to terminus. Typically, the value is map-measured by physical or computerized means. For non-loop trails, this is not the roundtrip length: double the distance if you plan to return the same way. Elevation change Hi/lo - Difference between high and low point of trail usu. the trailhead and terminus for most trails or the highest and lowest point for loop trails. Total - Total elevation change adding all climbs in one direction only. Difficulty Ratings min/min - minimal: usu. a flat walk at "best", a steep walk at "worst" nov/low - novice/low: appropriate for hikers who are novices, need to get into shape, or new to Oahu. int/mod - intermediate/moderate: appropriate for intermediate hikers - those who are not strangers to hiking on Oahu. Novices who are getting a good feel for Oahu trails may progress to this level. adv/high - advanced/high: only strong, advanced Oahu hikers should progress to this level. Trails which are tricky to navigate and require increased situational awareness may warrant this rating or higher. exp/ext - extreme: experts only, esp. those who can handle overly narrow, vertical, or precipitous cliffs. Skill level is a measure of personal abilities required to negotiate the trail. This is a mixture of technical skill (e.g. knowing how to traverse tricky, narrow, or steep sections requiring four-point climbs/descents) and pure physical strength and endurance. Danger level is a measure of exposure to and likelihood of a severe injury or death if you fail to negotiate the path properly, such as in a fall, misstep, or other mistake. Remember: there is always some form of this exposure on every trail on Oahu. This value merely judges the immediacy of such injury (i.e. the possibility of arresting a fall and avoid serious injury). Terrain coastal - unless a paved or dirt road, this trail type tends to be rocky and often undefined with no exact path to follow. Despite no major gain in elevation, boulders may require careful vertical climbs/descents. It maintains a close proximity to the ocean and therefore highly susceptible to dangerous waves. contour - graded trail without dramatic ups or downs - may have occasional switchbacks in steep areas hillside - trail tends to be hilly in nature, but ascents/descents are not as dramatic as a typical ridge trail. May include graded trails ridge-g - graded ridgeline: may involve a significant number of switchbacks ridge-u - ungraded ridgeline: footpath generally remains on top of the natural ridgeline and follows every change in elevation ridge-s - ridge spur: very sharp ascent, tends to be short in distance but difficult in steepness and footing. stream - majority of hike involves numerous stream crossings, remains parallel but very close to, or hikes in the stream bed. Footpath (if any) tends to be more natural, overgrown/boulder-strewn, and obscure. switchbacks - usu. ascent up the side of a ridge or cliff with the intention of reaching the ridgeline valley - other than a stream trail, usually involves more contoured or graded footpaths sometimes up and away from streams. Ascents may be a little steeper. Often involves at least one or more stream crossings, but less than five. Typically of a more constructed nature, but not necessarily.
