I was given an Oahu trail book last year and started exploring these wonderful trails on and around Pu`u Ohia (Tantalus). I found the trail system to be somewhat complicated, and I set a goal to make this natural resource more accessible for everyone else.
The trails are a part of the State of Hawaii Na Ala Hele trail system, however I've "adopted" this subset of trails. This map is the cornerstone of a much larger project to make the trails more accessible, including signage around the trails.
