Top 6 Waterfalls around Kailua

While many trails directly around Kailua can be challenging, for a truly family-friendly experience with safe swimming, consider Waimea Falls on the North Shore. It offers a paved walking path, shuttle service, and a lifeguarded swimming area, making it ideal for families. However, this option requires a drive from Kailua.

Historically, Maunawili Falls was known for its deep pool suitable for swimming. While the main trail is currently closed, it can still be reached via alternative, more challenging routes. Be aware that the stream water can carry leptospirosis bacteria, posing a health risk. For a safer, lifeguarded swimming experience, Waimea Falls on the North Shore is recommended, though it's a drive from Kailua.

The Ka'au Crater Trail is known for being very challenging, especially when wet. It involves slippery conditions, muddy sections, overgrown paths, and sometimes requires climbing steep walls. Similarly, reaching Maunawili Falls via alternative trails from Pali Highway is a strenuous and steep hike.

Yes, Waipuhia Falls, often called the 'Upside Down Waterfall,' is located near the Pali Highway. This unique phenomenon occurs when strong northeasterly trade winds blow the falling water upwards, creating the illusion of an inverted waterfall. It's best viewed from afar while driving eastbound towards Kailua, especially after heavy rains and during strong winds, as there is no dedicated lookout platform.

For waterfall hikes around Kailua, it's advisable to wear sturdy, waterproof hiking shoes with good grip, as trails like Ka'au Crater Trail can be very slippery and muddy. Long pants and sleeves can help protect against overgrown vegetation and mosquitoes, which are particularly bad around ʻAihualama Falls. Bringing insect repellent is also highly recommended.

Luaʻalaea Falls is a good option if you're looking for a less crowded experience. While it might be a bit harder to reach than the more popular Mānoa Falls, its lesser popularity means you have a good chance of enjoying the waterfall to yourself or with only a few others, especially after some rain.

The waterfall trails around Kailua offer lush tropical rainforests, dense jungle, and moss-covered landscapes. You'll encounter unique geological formations, rocky stream crossings, and diverse flora. For example, ʻAihualama Falls is set against a backdrop of thick jungle and moss, while the Ka'au Crater Trail leads to a hidden crater.

Beyond waterfall hikes, the Kailua area offers a variety of outdoor activities. You can explore numerous MTB Trails, go cycling, or enjoy running trails. Popular routes include the Ohana Trail Loop for mountain biking and cycling, and the Enchanted Lake Loop for running.

The main trailhead for Maunawili Falls has been closed for improvements since July 2021, and there is no official reopening date as of mid-2025. While the waterfall can still be reached via longer and more challenging alternative routes, such as from the Pali Highway, these trails are not recommended for casual hikers due to their difficulty, length, and lack of dedicated parking.

The water flow at waterfalls like ʻAihualama Falls and Luaʻalaea Falls is highly dependent on recent rainfall. To see them at their most impressive, visit after a period of rain. However, be aware that trails, especially the Ka'au Crater Trail, can become very slippery and muddy after storms, making conditions more challenging. Dry conditions are generally better for hiking safety.

Directly within Kailua, easily accessible traditional waterfalls are limited, especially with the closure of the main Maunawili Falls trail. For a more accessible waterfall experience on Oahu, though requiring a drive from Kailua, Mānoa Falls near Honolulu offers an easy stroll through a lush jungle. Waimea Falls on the North Shore is also very accessible with a paved path.
