7 Illegal Tour Routes in Hawaii That Can Get You Fined

Hawaii’s stunning landscapes draw visitors from across the globe, but not every trail, road, or shoreline is open to the public. Some areas are closed to protect fragile ecosystems or cultural sites, while others are off-limits for safety reasons or because they cross private property.

Tourists can accidentally enter these restricted zones by relying on outdated guides or unlicensed tour operators, risking fines or citations. The following outlines routes and areas in Hawaii that are considered off-limits, with practical notes on why access is restricted.

1. Ha’ik? Stairs (Stairway to Heaven), O’ahu

Few places in Hawaii carry the same mythic reputation as the Ha’ik? Stairs, known to most as the “Stairway to Heaven.” The climb, tracing a sharp ridge through the Ko’olau Mountains, is legendary among adventure seekers, yet it’s been off-limits to the public since the late 1980s.

Technically, the stairs were built during World War II for military communications, never for hiking. In recent years, the city has imposed steep fines (up to $1,000) for trespassers, and police patrols are frequent. It’s not just about safety, erosion and intrusion onto private property remain persistent concerns, and local residents regularly report illegal visitors.

There’s something undeniably magnetic about spots you can’t visit, but respecting closures is the only responsible choice. Legal alternatives, like the Moanalua Valley Trail (which stops short of the stairs), still offer dramatic vistas, without risking a brush with the law.

2. Sacred Falls State Park, O’ahu

“Why can’t we hike to Sacred Falls?” That’s a question I’ve heard more than once. The answer is rooted in tragedy: a deadly rockfall in 1999 led to the park’s permanent closure. Despite the shutdown, social media sometimes tempts visitors to take the risk, and that risk is not small.

There are now signs at every entrance, and police regularly patrol the area. Violators can face fines up to $1,000 or even jail time for trespassing. Nature hasn’t smoothed the way back either; the trail is overgrown and dangerous, with flash floods possible even on sunny days.

Sometimes, respecting a place means staying away. Sacred Falls remains a sacred site for Native Hawaiians, and its protection is as much about cultural respect as physical safety. There’s still much natural beauty to explore across O’ahu, legally and safely.

3. Makapu’u Tidepools, O’ahu

Makapu’u Tidepools lure with their crystal-clear water and ocean views, but the trek down is officially off-limits. Signs clearly warn against hiking to the pools, especially during high surf or strong currents. Sadly, accidents, including drownings, have occurred here, leading to stricter enforcement.

It’s not uncommon to spot warning tape or emergency rescue teams in the area. Choosing to ignore these warnings means risking both a fine and your safety. The tidepools themselves sit just below a popular lighthouse trail, making them deceptively accessible for the curious explorer.

Instead, I prefer sticking to the lighthouse trail above, where the views are just as stunning, and the rules are clear. The ocean demands respect, and Makapu’u is a vivid example of why certain places are better admired from a distance.

4. Dead Man’s Catwalk (Kamehameha Ridge), O’ahu

The story of Dead Man’s Catwalk is almost urban legend among Hawaii locals. The dramatic slab of concrete jutting out over the Kamehameha Ridge once drew social media fame for its epic views and edgy photos. But it sits on private land owned by Kamehameha Schools, and access is strictly forbidden.

Security measures include locked gates, fences, and signs that leave no room for doubt. Trespassers risk not only fines but also confrontation with local security or neighbors tired of unwanted visitors. The catwalk itself was removed in 2016, yet the allure persists, fueled by viral posts and outdated trail guides.

I’ve learned that the best adventures don’t need to break the law. If you’re after panoramic views, there are many legal hikes in the area that offer just as much magic, minus the legal trouble.

5. Toilet Bowl Swimming Hole, Hanauma Bay, O’ahu

Toilet Bowl in Hanauma Bay has an unforgettable name and a reputation that matches. The swirling, geyser-like pool forms when waves crash into a hollow in the lava rock, but what was once an adventurous swim spot has been closed due to numerous injuries and several fatalities.

Park authorities added warning signs and barriers years ago, urging visitors to stay away. Still, some try to sneak in, risking not only a fine but also unpredictable currents that can pull swimmers under. The trail itself is rough and slippery, adding to the hazards.

I used to think hidden gems like this were worth seeking out, but after seeing the consequences, I recommend staying on marked paths. Hanauma Bay offers plenty to enjoy above water, from snorkeling to scenic overlooks, all within the rules.

6. Peace Sign Pillbox (Ehukai Pillbox Hike), O’ahu

Peace Sign Pillbox is a favorite spot for North Shore hikers, instantly recognizable thanks to its graffiti artwork. What many visitors don’t know is that the second pillbox sits on private property, making access illegal. Local landowners have posted signs, but they’re often ignored in pursuit of that perfect Instagram shot.

Trespassing here is not just a minor infraction, officials have started issuing fines to discourage repeat offenders. The area’s popularity has even led to increased patrols during busy seasons. It’s a reminder that well-trodden paths aren’t always legal ones.

There’s still plenty to explore on the legal sections of the Ehukai Pillbox Hike, with panoramic views stretching over the coast. For me, respecting property lines is part of being a good guest on the islands.

7. Kahaualea Natural Area Reserve, Big Island

Kahaualea Natural Area Reserve isn’t just closed, it’s a strict no-go zone. State officials have prosecuted unlicensed tour guides who lead groups into this fragile ecosystem. In one notable case, a guide was arrested and charged for conducting illegal tours here in 2015.

The reasons go beyond safety. The area protects unique volcanic landscapes and rare species, many of which are threatened by human disturbance. Even small groups can cause lasting damage to sensitive habitats, so enforcement remains tough.

When exploring Hawaii, I’m always struck by how much care goes into preserving its wild places. Legal reserves and parks nearby offer just as much beauty, where you can hike without worry, and with a clear conscience.
