Hau’ula Loop trail is not for the faint of heart. Although relatively short, around 3 miles, the trail is a steep climb packed full of roots and rocks that will prove a challenge to most. More photos and videos at: http://www.mtbhawaii.com/trails/hauula_loop.
Bike is a Santa Cruz Nickel.
Song is 'Punching In a Dream' by The Naked and Famous.
