Tougher than the nearby Hauula" class="redactor-linkify-object">http://www.mtbhawaii.com/trail... Loop Trail, Ma'akua Ridge Trail offers a gnarly climb, with steep, tight switchbacks full of rocks, roots and cliffs.
There is not much parking near the trail entrance. There is parking on Kamehameha Hwy near the 7-11 or across the street at the beach park. From there it's a short ride north to Hauula Homestead Road. Head down Hauula Homestead Road for about a half mile. When it starts bending to the left be sure to stay straight on towards the mountains. Pass through the yellow gate, proceed to the next gate and ride about 100 yards until you see the trail sign for Ma'akua Ridge Trail on the left.
The trail curves to the left and soon you will see a stream bed on your right you will need to cross. Cross the stream bed to begin your ride. Soon will you reach the first switchback and the fun begins! As you progress up several more switchbacks you will reach a point where the trail forks allowing you to choose which direction you want to head around the loop. There is a park bench here with a beautiful view of the ocean to relax on before you start the remainder of your ride.
This trail is tough. I tend to ride it when I want to relax, take it slow and enjoy the beauty of the islands. Someone has built a covered area with a picnic table so feel free to pack a lunch and know you will be able to sit down and enjoy it.
