Moanalua Valley Trail to Haiku Stairs is a dirt and rock path that leads to the backside of the Stairway to Heaven, also known as Haiku Stairs.
The Stairway to Heaven is an old metal staircase that climbs up the ridge above Haiku Valley. It was built in 1942 as part of a naval radio station and has been closed to the public since 1987 due to safety and legal issues.
The Moanalua Valley Trail is long and challenging, with some stream crossings, switchbacks, ridges, and ropes along the way.
The trail ends close to the top of the Stairway to Heaven, where you can see the windward coast, Kaneohe Bay, and Kailua Beach. Note, the act of being on the Haiku Stairs is ILLEGAL.
You can also see the sun rising or setting over the water, creating a spectacular sight in the sky.
5 Best Oahu Hikes Now Illegal or Closed!
Some of the iconic best trails in Oahu are now closed for various reasons, including safety, environmental, or legal issues.
With so many other amazing Oahu hikes listed above, do not risk fines, arrests or personal safety by trespassing illegally on the below trails.
1. Haiku Stairs Trail (Stairway to Heaven)
- Reason for closure: Safety and legal issues
- Penalties for trespassing: $1,000 fine and/or arrest
The Stairway to Heaven (Haiku Stairs Trail) was probably THE iconic trail in Oahu. Alas, no more! The stairway was damaged by a storm and since then closed for safety reasons.
Starting in April 2024, the famous Haiku Stairs are being permanently removed.
The Moanalua Valley Trail to Haiku Stairs described above takes you close to the top of the stairs, but being on any part of the Haiku Stairs Trail itself is illegal.
2. Crouching Lion Trail
- Reason for closure: Environmental issues
- Penalties for trespassing: $500 fine and/or arrest
The Crouching Lion Trail, another very popular trail was closed indefinitely in 2021.
The hike on Crouching Lion Traill provded excellent views of Kahana Bay, Mokolii Island (also known as Chinaman’s Hat), and the Ko’olau Range.
The trail is closed to protect the native plants and animals that live in the area. The trail is also eroding and causing landslides that threaten public safety.
3. Hamama Falls Trail
- Reason for closure: Safety issues
- Penalties for trespassing: $500 fine and/or arrest
The Hamama Falls Trail to a beautiful waterfall has been closed since 2021.
The trail is closed due to safety concerns related to rockfalls, landslides, flash floods, and crime. The trail is located on private government property owned by the Honolulu Board of Water Supply, which does not allow public access.
4. Maunawili Falls Trail
- Reason for closure: COVID-19 pandemic
- Penalties for trespassing: $500 fine and/or arrest
Maunawili Falls Trail is a dirt and mud path that follows Maunawili Stream into Maunawili Valley to Maunawili Falls, a beautiful waterfall. This trail is temporarily closed since 2021, but expected to re-open, probably in 2024.
An alternative trail to Maunawili Falls is the Maunawili Demonstration Trail that can be accessed from Pali Highway (see note above)
5. Ka’au Crater Trail
- Reason for closure: Safety issues
- Penalties for trespassing: $500 fine and/or arrest
The Ka’au Crater Trail was a popular hike to three waterfalls, and a stunning view of the island from the ridgeline.
The trail is closed due to safety concerns related to rockfalls, landslides, flash floods, and crime. The trail is also dangerous and unstable due to weathering and vandalism.
The Ka’au Crater Trail is located on private land owned by various landowners, who do not allow public access.
Hiking Gear Checklist
Many of Hawaii’s hikes are demanding, make sure you are well equipped and well prepared. Here’s what we typically take with us:
- Water Bottle: I hate plastic bottles, and with opaque bladders you can’t see if it is moldy inside. We use this Hydro Flask water bottle – light, stainless steel, wide mouth (you can add ice), with double-wall vacuum insulation (greatly refreshing for hikes in summer). You can also get it with a Flex Straw Lid!
- Hiking Shoes: My preferred hiking shoes are the medium range Merrell Moab 3 Waterproof Hiking Shoe (men’s, women’s, men’s mid), great for Hawaii’s trails through mud and streams. My wife loves her high-end Salomon X Ultra 4 GTX Hiking shoes (men’s, women’s), also waterproof.
- Sunscreen: Hawaii’s sun can be harsh. Avoid sunburn with sunscreen compliant with Hawaii’s 104 Reef Act. The Sun Bum Original SPF 50 Sunscreen Spray, moisturizing with Vitamin E, is our go-to when we travel to Hawaii. Apply liberally and regularly!
- Trekking Poles: Great for hikes that involve climbing, both going uphill and downhill, and on trails that are wet, muddy and slippery! Improve your footing with this collapsible, high-end Black Diamond Trail Cork Trekking Poles, available for men and women.
- Headlamp: Planning a sunrise or sunset hike? Hiking in the dark is no fun, especially on many of Hawaii’s rainforest or ridge hikes. We love these two headlamps: the budget Black Diamond Spot 400 Headlamp and the premium Petzl Actik Core Headlamp, with many features.

Where to Stay in Oahu
Honolulu (Waikiki in particular) offers a large number of hotels and resorts, along with shopping and dining options. Most visitors to Oahu choose to base in Honolulu at least for a part of their stay.

Our faves include Halekulani for a splurge stay, the Lotus Honolulu for views of Diamond Head, and The Laylow for its awesome location.
