Diamond Head Luau
I've only been to the Diamond Head trail a few times. It's an extremely pleasant climb for daily hikers, but a slight challenge for those new at it. The steep staircase was the toughest part of the climb for me, and ducking through those low boulders was a bit claustrophobic. But he view at the very end is well worth the climb!
Manoa Falls Trail
This hike was included with the pass! Be careful if it's been raining, the rocks get really slippery and there are no rails. When I went, someone along the trail broke their ankle and had to be airlifted out. Beautiful hike though! There's a nice snack shop at the bottom with shave ice; perfect for an after hike snack!
