Where to Hike: Oahu

Hawaii, Oahu, Travel, United States

Vacations with me are never really overly relaxing… I always have to be on the go, whether that means hiking, biking, shopping, or trying a new workout class. For our Hawaiian vacation, we opted for a lot of hiking since neither of us are beach people. We hiked over 70 miles… I still can’t believe it!
We hiked all types from easy/beginner level to advanced/expert. Here’s our favorite hikes!
Kaniakapupu Ruins

Lulumahu Falls Trail
Lulumahu Falls Trail first waterfall:damn
Lulumahu Falls Trail 1
Lulumahu Falls Trail 2
Just past the start of Kaniakapupu Ruins Trail is the start to Lulumahu Falls. You’ll hit a small damn that is waterfall-like, but keep going! There are a few river crossings. The waterfall at the end is gorgeous and you can walk (or swim) out to it! The trail is under cover, but you’ll need bug spray!
Difficulty: Intermediate
Length: 2.5 miles
Wet/Dry: Wet
Wa’ahila Ridge Trail
Wa'ahila Ridge Trail 1
Wa'ahila Ridge Trail bouldering

Koko Crater Railway

1,048 steps up the side of the crater made from an old railway bed. It looks short… until you’re halfway up. Don’t let this short trail fool you, it’s very strenuous in the blazing sun!

Diamond Head Crater

Diamond Head Crater Trail

On our first attempt to get this trail, we were turned away because there was no parking left. So the second time we parked outside the crater and walked in. This is an incredibly popular trail, but the views from the top are pretty good. Beware of the gnats at the top though!
Difficulty: Easy
Length: 1.5 miles
