Wahoo Rock is the most frequently dived site in Coiba National Park and for good reason.

It has the highest potential for whale shark encounters. The site is a giant rock protruding out of the water, with a flag at the top.

The water column here is COVERED in plankton, attracting filter feeders like whale sharks, sting rays, manta rays, and more.

I was lucky enough to see two whale sharks on my second dive here.
Hard to make out in the pic, but the haze is ALL plankton.

The rock sits inside Panama's protected UNESCO World Heritage marine reserve, which means the marine life here is largely undisturbed. This makes it one of the best dive sites I've visited in the Eastern Pacific.

The Dive

The dive itself is typically a lap around the rock, but the main feature isn't the structure itself.

Wahoo Rock generates massive fields of plankton, visible as a haze in the water, which draws filter feeders from across the park.

Devil rays, manta rays, and whale sharks all come here to feed.

On my two dives here I encountered a large school of devil rays and two whale shark sightings on the second visit.

The bottom of the site is very volcanic rocky looking, similar to many other Pacific dive sites I've visited.

Marine Life

Wahoo Rock has the highest whale shark encounter potential of any site in Coiba National Park.

On my dives I spotted devil rays, frog fish, whale sharks, hawk fish inside hard coral formations, garden eels, and so much more.

Diving Conditions

Wahoo Rock is on the Pacific side of Panama, giving it unpredictable water temperatures, currents, and visibility.

According to Coiba Dive Center guide Kat, who has been diving this park for over a decade, my trip got lucky with conditions warmer temps, manageable current, and reasonable visibility.

Water temperatures run cooler with strong thermoclines.

I wore two 3mm wetsuits on a lot of the dives here.

One thing to be prepared for when diving in the Pacific: thermoclines.

The water can shift from 81°F to 75°F within 10 feet of depth change, and you'll feel it immediately.

The best approach is to ascend back into the warmer layer unless there's something worth pushing through for.

Conditions can vary significantly, so diving with a local operator who knows the park is strongly recommended.

Diving Wahoo Rock in Coiba, National Park

Wahoo Rock is the most dived site in Coiba National Park and Panama's best shot at a whale shark encounter. A giant rock rising out of the Eastern Pacific, it generates dense plankton fields that draw devil rays, manta rays, and whale sharks into the water column around it. At 85 feet max depth with moderate current and Pacific thermoclines, it's an intermediate dive given the cold water, low visibility, and unpredictable currents. .On my second visit, it delivered two whale shark sightings.

Diving the Odyssey Wreck in Roatan, Honduras

The Odyssey Shipwreck is Roatan's most impressive dive — a 300-foot cargo freighter deliberately sunk in 2002 that now sits at 110 feet off the coast of Roatan. It's one of the largest shipwrecks in the Caribbean and has developed into a thriving reef ecosystem .This is an advanced dive with limited bottom time on the wreck itself, but the surrounding reef lets you extend well past 45 minutes.
