There are actually two trails here.  The first trail runs through the valley.   It is a short challenging  ride that starts out along side a stream bed for the first 3/4 of a mile that then becomes a rocky foot path. Plenty of roots and rocks which can be slippery when wet.  This trail is short and only goes in less than a mile

The second trail is the ridge trail, which is a challenging ride with multiple switch backs up the right side of the valley.  When you reach the picnic table at the top, the trail becomes suitable only for hiking.  After playing around on the small hills near the picnic table, you can either go back the way you came, or take the trail that is behind the picnic tables.  The trail behind the picnic tables is a fun, fast, technical rock spewn trail that ends at the next valley over from where you parked.   Make sure to veer to the left at each fork. You will have to ride back on the streets to get to your car, but it is well worth it. 

Pupukea

How to get there: Take H1 west to H2 north. Go through Wahiawa following Kamehameha Hwy. to Haleiwa. Go past Waimea Bay and turn right just before the  Food Land supermarket.   Follow Pupukea Road all the way to the top and park at the end of  the road.   The trail head is at the gate straight ahead next to the Boy Scout camp.

Right after passing through the first gate, you will see a second gate to your Right.   This is the start of the down hill trail into Waimea Valley.  This is a private trail and there is a usage fee. You must register for access at Waimea Falls Park before riding on this trail. The Hawaii Mountain Bike Adventures at Waimea Falls Park runs a shuttle from Waimea Falls Park to the top of Pupukea Road on Sundays.
The main trail is the Kaunala (Cambodia) trail.  To find this trail, follow the dirt road from the Boy Scout camp about a half mile until you find the single track to your left.  This trail connects back to the dirt road where you will be able to find your way back, or continue on towards Kahuku.  This is an awesome trail about 5 miles.

Another good ride is park your car at the park across from the Pupukea Foodland and ride up Pupukea Road to the trail head. You can ride this dirt road all the way to Kahuku by veering left at the first fork about a quarter mile past the Boy Scout camp (If you turn right at the gate, it is another entrance into Waimea Falls Park).  Follow the road all the way to Kahuku.   From Kahuku, you can follow Kamehameha highway back to the Pupukea Foodland where you began.

Distance: about twenty miles

St. Louis Heights

How to get there:  Take H1 east and exit at the University Blvd. exit.   Follow University Blvd. uphill towards UH and take your first right at Dole Street.   Follow Dole Street past the UH dorms until you see a small park on your right.   Park in this area.   From here, you can either shuttle riders to the top, ride your bike to the top, or take the city bus.
