If you’re coming over from our reel, welcome! I promised I’d break down my favorite waterfalls (and a few bonus hikes) in more detail, so here it is. These are the spots I send friends and family to, and the ones I personally go back to over and over.
My Top 3 Waterfalls on Oahu
1. Manoa Falls
This is the classic and for good reason. It’s a short, well-maintained trail (about 1.6 miles round trip) through a lush rainforest that feels like something out of Jurassic Park, because parts of it actually were used in Jurassic Park. The trail is mostly flat with some root-covered sections and mud, so wear real shoes, not slippers. You’ll reach a 150-foot waterfall at the end. Heads up: swimming isn’t allowed here due to falling rock debris, but it’s still one of the most rewarding short hikes on the island. Get there early, the small parking lot fills up fast, and it’s also one of the most popular hikes with visitors.
2. Lulumahu Falls
This one’s a bit more of a hidden gem. It’s near Manoa but sees way less foot traffic, which makes it feel more like a real adventure. The trail is about 2.5 miles round trip and can get muddy and slippery, with a stream crossing or two, so I’d rate this moderate rather than easy. The payoff is a beautiful multi-tiered waterfall with a pool at the bottom. Bonus: legend has it that ancient Hawaiians used the black rocks near here to color kapa (bark cloth), which is where “Lulumahu” gets part of its story.
3. Waimea Valley
This is the most “guided experience” of the three, and that’s exactly why I love recommending it to first-timers or families. Waimea Valley is a botanical garden and cultural site on the North Shore with a paved, easy path leading to Waimea Falls and this is one of the few waterfalls on Oahu where you can actually swim (lifeguards on duty, life vests provided). Along the way you’ll pass native Hawaiian plants and cultural sites with info on traditional practices. It’s not free like the other two, but it’s a great half-day stop if you’re already exploring the North Shore.
A Few More of My Favorites
Makapu’u Lighthouse Trail
An easy-to-moderate paved trail (about 2 miles round trip) with some of the best coastal views on the island. You’ll get sweeping ocean views, the lighthouse itself, and during winter months (roughly November through May), a great shot at spotting whales. There’s basically no shade, so bring water and sunscreen.
Koko Head
This one’s not for the faint of heart. The Koko Head Stairs are a former railway track with over 1,000 steps, straight up a steep ridge. It’s brutal, but the summit views over southeast Oahu are some of the best you’ll find anywhere. Go early to beat the heat, there’s zero shade and the metal ties can get hot in direct sun.
Lanikai Pillbox Hike
A short but steep climb (around 1.5 miles round trip) right above Lanikai and Kailua. You’ll pass old WWII-era pillbox bunkers along the ridge, with panoramic views of the coastline and the Mokulua Islands below. It’s popular for sunrise, so expect company if you go early.
Pink Pillbox Hike
Don’t confuse this with the Lanikai pillboxes above, this one’s on the opposite side of the island near Waianae, also known as the Puu O Hulu or Maili Pillbox hike. It’s a short, moderately steep trail (around 1.4–1.5 miles round trip) that climbs a series of switchbacks to a ridge lined with several old pillbox bunkers, including the pink one it’s named for. The views stretch across the Waianae coastline, and it’s one of the best sunset spots on the island since you’re facing west. There’s little shade, so go early morning or late afternoon, and skip leaving valuables in your car, break-ins have been an issue at the trailhead.
Wrapping It Up
That’s the rundown! Three can’t-miss waterfalls and four more hikes that make my personal Oahu bucket-list. These are the places I keep coming back to, and I hope they end up on your list too.
