Easy Kohala shore dive for nudibranchs and other small critters
Easy Kohala shore dive for nudibranchs and other small critters
NudiMadness is a tiny, easy shore dive on the Kohala Coast built for slow searching rather than depth. The shallow reef and sandy bottom make it a good place to spot nudibranchs, small reef fish, octopus, and other invertebrates, with turtles and bigger sea life showing up on the right day. It works best when surf is low and you can take your time on the entry and exit.
Safety Notes
Keep the entry and exit deliberate, use a dive flag, and avoid kicking up sand while you search for tiny subjects.
Access Restrictions
Shore-entry gear and local shore-diving etiquette matter more than depth here, especially when surf is up.
Legal Notes
Follow local shoreline rules, use the required flag and marker gear, and respect marine life and reef contact limits.
Community notes to help plan your visit.
Scuba Diving
Slow shore dive with almost no depth to manage, making it ideal for careful critter hunting and buoyancy practice.
Freediving
The site is shallow enough for breath-hold looks on calm days, but the best experience is still slow scuba or snorkel-time searching.
Snorkeling
Snorkeling works well when the surf is low because the site is so shallow and the critter life sits close to the surface.
