The question always arrives the same way, usually a few minutes into our very first phone call. A mom lowers her voice like she is about to confess something and asks me, what are the best hikes on the Big Island of Hawaii. After all, she already knows her family cannot survive a whole week of beach chairs and shave ice alone.

I love that question, because it means she is thinking past the postcard. The state of Hawaii is made up of several islands. The island she is asking about, the one locals simply call the Big Island, is the only one in the whole chain where you can stand in a rainforest, a lava field, and a cattle ranch pasture all within the same afternoon. That range is exactly why the hiking here deserves more than a quick beach day.

Every Family I Know Asks Me the Same Thing First: What Are the Best Hikes on the Big Island of Hawaii?

The Question Every Family Asks Me First About the Best Hikes on the Big Island of Hawaii

Before I hand any family my list, I picture the actual people standing at the trailhead. There is almost always a grandmother who wants to see something beautiful without needing a knee replacement to prove it. There is a five-year-old who will hike exactly as far as the promise of a swimming hole or a waterfall will carry her, and not one step further. And there is usually a teenager somewhere in the group who has already decided hiking is boring. Well, right up until the trail gets a little steep and a little wild and suddenly it is the best part of the trip.

That is the real question underneath every version of the best hikes on the Big Island of Hawaii that people type into their phones at midnight while everyone else in the house is asleep. It is never really about the trail. It is about finding the one hike that works for every person in that specific group, on that specific day.

What a Big Island Hawaii Vacation Feels Like Once You Leave the Resort

Here is what surprises most families about a Big Island Hawaii vacation. Most of them land in Kona. They check into a resort along a coastline that looks almost like a desert with all black lava rock and dry brush rolling down to a startling blue ocean. Then they assume the rest of the island looks the same.

Then they drive an hour and a half across the island toward Hilo, and the whole world changes color. The air gets heavier and sweeter. Rain clouds sit low over the mountains most afternoons. And everything, every single hillside, turns an impossible, dripping green.

That is where nearly every waterfall on this island is hiding. All tucked into the side of the island most first-time visitors never planned to see.

Easy Waterfall Hikes on the Big Island That Even the Reluctant Hiker Will Love

When people ask me for the best hikes on the Big Island of Hawaii, this is usually where I start. These three waterfalls give you the biggest reward for the smallest amount of effort a family can spend on a Hawaii trip.

Akaka Falls Trail, the One I Send Every Family to First

Picture a paved path curling gently uphill through a wall of bamboo so thick it swallows the sound of the parking lot behind you. Within a few minutes you pass Kahuna Falls through a gap in the trees. This is a smaller, quieter waterfall that most people almost miss because they are already listening for the bigger one.

Then the trail opens, and there it is. Akaka Falls drops four hundred and forty-two feet straight down a cliff face into a green pool below. I have never once watched a kid stay quiet when they first see it.

The whole loop is under a mile. It is paved the entire way. And it includes a few gentle stairs. This makes the Akaka Falls hike one of the only waterfall hikes in the entire state that genuinely works for a stroller or for a grandparent who cannot manage loose rock or mud.

Last time I checked, the park charged around fifteen dollars per person to enter. Although, I always confirm the current rate with my clients before they go, since Hawaii’s park fees have a habit of shifting from year to year.

Rainbow Falls Hilo, the Waterfall You Can See Without Breaking a Sweat

Some waterfalls ask nothing of you at all, and Rainbow Falls Hilo is one of them. You pull into a small parking area just outside downtown Hilo, walk maybe a hundred feet along a paved path, and the falls are simply there. Eighty feet of white water crashing into a wide pool below a lava rock ledge.

On a sunny morning, mist off the falls catches the light and throws an actual rainbow across the pool. Which is exactly how the place earned its name.

This is the waterfall I recommend when a family has a baby who just went down for a nap in the car seat. Or when jet lag has wiped everyone out and nobody has the energy for a real trail.

It belongs on nearly every list of Big Island waterfall hikes with kids for exactly that reason. One honest note, since I would rather you hear it from me than find out at the trailhead: Swimming is not permitted here. So, plan on this as a beautiful stop rather than a splash day.

Umauma Falls and the Hawaii Tropical Bioreserve and Garden, for the Family That Wants a Slower Morning

Not every family wants to hike a trail. Some want a morning that unfolds slowly. That is exactly what you get at the Hawaii Tropical Bioreserve and Garden. This is where manicured paths wind through thousands of tropical plants before delivering you to Umauma Falls. The falls are a wide, multi-tiered cascade that tumbles down in three separate drops.

Because the paths here are wide, mostly flat, and built for garden visitors rather than hikers, this is often the spot I suggest when one member of the family cannot walk far but still wants to feel like they saw something extraordinary.

Plan a little extra time for this stop. Nobody rushes through this garden, and that is entirely the point.

Big Island Waterfalls That Look Incredible in Photos but Are Not Real Family Hikes

Not every stunning photo online tells you the whole story. This is the part of the conversation I have with almost every client before they book a single activity, because a few of the most photographed Big Island waterfalls are simply not built for a family hike.

Waipio Valley, the View Worth the Drive Without the Steep Walk Down

Waipio Valley is the tallest waterfall in the entire state of Hawaii. It drops nearly fifteen hundred feet down a cliff face at the back of a valley so lush and deep it looks like something out of a different era entirely.

From the overlook at the top, you can see the black sand valley floor spread out below. It is wrapped in cliffs on three sides and open to the ocean on the fourth.

Here is what most articles do not tell you clearly enough. The road down into the valley drops at a grade steep enough that rental car companies forbid it. And the hike down and back is not something I recommend for young kids or for anyone with hip or knee trouble.

If your family wants to experience the valley floor itself rather than just the view from above, book a shuttle or a guided tour instead of attempting the walk. The overlook alone, reached by a short, flat path from the parking area, is worth the drive on its own.

Best Hikes on the Big Island of Hawaii Beyond the Waterfalls

Waterfalls get most of the attention, but they are not the whole answer to best hikes on the Big Island of Hawaii. Some of the most memorable trails on this island have nothing to do with water at all.

Pololu Valley Awini Trail, a Short Walk with a Coastline Payoff

At the very end of the road on the northern tip of the island, the pavement simply stops, and a short, half mile trail switchbacks down into Pololu Valley. The walk down takes maybe fifteen minutes, but the reward is immediate. There is a wide black sand beach framed by jagged sea cliffs that stretch on toward the horizon in one direction after another.

Kids love scrambling over the smooth, dark lava rocks scattered along the shoreline here, worn round by decades of ocean waves. Just remember that whatever you walk down, you eventually have to walk back up. So, save a little energy and a little patience for the return climb.

King’s Mamalahoa Trail and the Story Written in Lava Rock

There is a stretch of trail near the Kohala coast where the ground itself becomes a history book. Thousands of petroglyphs, somewhere near thirty thousand of them, are carved directly into the old lava flows along the King’s Mamalahoa Trail. There are images of people, canoes, and symbols left behind by generations of Hawaiians who walked this same path centuries before any hotel existed on this coastline.

I have watched restless kids go completely silent here, crouched down, tracing the outline of a carved figure with one finger, asking questions I cannot always answer.

Bring sunscreen and water, since there is very little shade, but do not rush this one. It rewards a slow pace far more than a fast one.

Kalopa State Park, Two Trails for Two Different Kinds of Hikers

Kalopa State Park quietly solves a problem almost every family runs into eventually, which is that not everyone in the group wants to hike the same distance on the same day. The short, gentle Kalopa Nature Trail loops through native rainforest in well under an hour. It is perfect for younger kids or anyone easing into the day slowly.

For the more energetic half of the family, the Kalopa State Park Perimeter Trail stretches three and a half miles through a much wilder stretch of forest, following either the Jeep Road or the Gulch Rim Trail, which I always steer people toward for better views.

Split the group here if you need to. Everyone can regroup afterward at the picnic tables with a story to tell.

Kilauea Iki Trail, for the Family Members Who Want a Little More Adventure

If part of your group is craving something a little wilder, the Kilauea Iki Trail delivers it. The just over three-mile loop starts in a genuinely lush rainforest. It then drops you down onto the floor of an old volcanic crater, where steam still rises quietly out of cracks in the rock decades after the eruption that formed it.

I usually reserve this one for the more adventurous half of the family, teenagers especially. The crater floor hike adds real distance and a warm, otherworldly landscape that younger kids sometimes find more unsettling than exciting.

It earns its place near the top of the best hikes on the Big Island of Hawaii for anyone traveling with an older kid who wants to feel like an explorer instead of a tourist.

Things to Do in Hilo When You Are Not Hiking

Hiking does not need to fill the whole day. Thankfully, Hilo gives you plenty of options to fill the rest of it.

Wander through the farmers market downtown on a Wednesday or Saturday morning for fresh fruit your kids have never tried before. Browse the shops along a walkable historic strip. Or stop by the tide pools at Richardson Ocean Park for an easy, low-key afternoon after a morning on the trail.

If the weather turns, and on this side of the island it eventually will, the Imiloa Astronomy Center gives the whole family a rainy-day plan that still feels like part of the adventure rather than a backup plan.

I like pairing one waterfall hike with one town stop each day here, so nobody feels rushed and nobody feels bored.

Best things to do in Hawaii during your family vacation. 

Planning Your Big Island Family Vacation Around These Hikes

A Big Island family vacation comes together best when the hikes are not an afterthought squeezed between pool days, but a real activity running through the whole trip. That usually means basing part of your stay closer to Hilo. Or at minimum, blocking out full days for the drive across the island rather than trying to squeeze a waterfall in on the way to somewhere else.

Best Hikes on the Big Island of Hawaii, Hilo Side Versus Kona Side

One of the first questions I ask every family planning a Big Island trip is simple. Are you planning on staying in Kona, in Hilo, or splitting your time between both? Nearly every waterfall on this list sits on the wet, green Hilo side. It is roughly a two-hour drive from the Kona coast. So, a family based entirely in Kona needs to plan a full day, not a quick side trip, if they want to reach them.

That drive time is exactly why I sit down with every client before they book a single hotel night, because the best hikes on the Big Island of Hawaii only work well inside a trip that is genuinely built around them, not squeezed in as an afterthought. If you want help sorting out where to stay, how many days to stay on this side of the island, and which of these trails fit your family best, that is the exact conversation I would love to have with you next.
