North of Honolulu and Kahaluu on Oahu, the 5,200 acre Kahana Valley State Park has a 4.9 mile one-way trek along Kahana stream through a lush forest.
The park is located on Kamehameha Highway (SR83).
Here are some notes on adventuring in Hawaii. First, unlike mainland forests, the tropical island forests can grow very dense and can mask dropoffs. Plus, the trails can be very wet and slick most of the year (December to February is the main rainy season, but expect rain all year round). Stay on the trail to avoid disorientation. Second, speaking of disorientation, be aware that most Hawaiian topographic maps use the Old Hawaiian Datum. When trying to use the latitude/longitude from those maps with a GPS unit, you will think you are 0.4 miles south/southeast of where you really are. Kind of important in a dense jungle. Third, the bacteria Leptospirosis is found in the local waters and mud. It causes flu like symptoms within 2-20 days of contact, and can be fatal if not treated with antibiotics. Fourth, when hiking about, walking sticks can be very helpful for stablity in the slick conditions, for probing mud hole depths and clearing webs of the tiny crab spider.
Overall, Kahana Valley State Park is the 16th most popular hiking trail of all 45 hikes in Hawaii. Several of the better hiking trails are nearby Kahana Valley State Park including Ka ena Point State Park, Haiku Trail, Mariners Ridge Trail - Kaluanui Ridge Trail, Diamond Head Crater Trail and Pali (Maunawili) Trail.
