Just returned from my sixth trip to Bonaire, from January 3-10, 2025. My wife calls Bonaire her "happy place" and we enjoy the island's laid-back culture and freedom of diving. On this trip, we did 15 dives, from Red Slave in the south, to Tailor Made in the north, to the East Coast, and while we found much to enjoy, we came away feeling sad about the state of the corals. I thought I would share a few observations:

1. Throughout the island, the hard corals have gone from bad to worse, and from worse to dead. My previous trip was in January 2024, and there was widespread evidence of SCTLD and bleaching. This time around, there was much less sign of SCTLD and bleaching, but that's because there was just a lot of dead coral, covered in algae. We chatted with some first-time divers to the island who thought that corals seemed healthy, because they saw coral structures with no visible signs of bleaching -- but I think they were just equating "structure" with "alive." For instance, we chatted with a couple after a dive to Invisibles, who thought that the corals at the 50 foot level on that site were "not bad." My wife estimated that the hard corals were 80-90 percent dead.

2. The hard corals were particularly bad on the East Coast, which was heartbreaking, as corals on the East Coast were just pristine 7-8 years ago.

3. Staghorn corals, which were still very much thriving a year ago, are now mostly dead -- in the south, in the north, and the East. That was perhaps the saddest thing I saw this year.

4. In terms of animal life, the East Coast still provides some outstanding diving, with turtle cleaning stations, aggregations of tarpon, southern stingrays, seahorses, pelagics of various stripes, etc.

5. East Coast Divers has lost two of its longtime guides, Sid and Martin, who are still on the island but are now doing their own guided trips. But the company still provides pretty much the same service, with different guides. I would still recommend them. One thing the current guides mentioned on this trip is that while the turtle population on Bonaire is still very high, they are starting to eat up all the seagrass, which might put a limitation on their numbers.

6. On the west side, the southernmost sites still have some gorgeous soft corals, and the northernmost sites still have some relatively abundant live hard corals. They are more challenging to access and to dive, and not for beginners, but they are decidedly better than the dive sites in the middle of the island. Even in those better sites, the damage was impossible to ignore.

It's hard to complain about a place where we were able to do 15 dives, including two boat dives, at a cost of $300 a person, where we rented a truck for $300 a week, and stayed in comfortable accommodations for $80 a night, where we befriended fellow divers and enjoyed many laughs and good cheer, and where the weather was gloriously sunny pretty much the whole week, even during the Bonaire "winter." For my wife and me, Bonaire is one of the attractive and most accessible dive destinations, because we can fly essentially for free with frequent flyer miles, and catch an early morning flight and be diving the same day. WIth all that said, we really were taken aback by how much the corals have declined over the last two years, and that cast a sad cloud over an otherwise pleasant trip.
 
I haven't been back since October/November 2023....this last year is the first year we didn't go in the last 10 yrs I believe. In 2023 we were there at probably the peak of the coral bleaching that year + SCLTD. It's definitely a weird feeling about going on a trip and being excited but then going underwater and being sad all week because of what you see.

This being said we've seen the same thing at Little Cayman too, we were there May 2023 and everything looked good. Went back in July 2024 and the reef had took a huge hit from the bleaching event that took place in 2023 as well. Talking to the guides at reefdivers they said ccmi estimated that 50-65% of the coral died.

We also went to Cuba this past November and you could tell they were also hit bad with bleaching and had a lot of death. There were quite a few people on the trip that talked about how bad the reefs looked.....it was odd because I thought they actually looked good compared to what I saw in LC and Bonaire last. They definitely struggling and there was now a lot of algae everywhere but still very very fishy/sharks everywhere.

We've decided for the next few years to just take less number of trips, but go farther and longer and give the Caribbean some time to recover. (obviously the species that got hit by sctld may not come back, not sure how all of that will play out long term).

On the bright side, this Philippines this last year the coral life looked great.

I was there the same time (July-Aug 2023) and couldn’t agree more. The dives were more often sad than enjoyable. Hard corals are my favorite thing underwater, they’ve been eviscerated. At that time, there was still a sense of hope the currents would keep it primarily on the West side and out of the North. The same trip I found several early stage patches of SCTLD on the east coast; that’s when I sadly made the mental note that this was likely going to be my last Bonaire trip for a long time. A first time visitor would probably still find it amazing.

Any more info on this? Do you happen to know the names of their new ventures? Are they working together? They’ve always been the core of that team, my last trip they were mixing in Amber amongst them. Great DMs and people!

Martin and Sid are both on the island, and doing freelance guiding, separately from each other. I did a “bonfire” night dive with Martin on this trip, which was interesting; he hung some bright lights from a buoy that attracted plankton, and then we looked for larval critters that were drawn to eat the plankton, including morays, filefish, blue tangs, and shrimp, all of which looked very weird but recognizable in their larval stage. (A larval moray is the length of your pinkie and not much thicker than spaghetti, yet still can be recognized as a moray.). You can find Martin at this link: Home - Twilight Diving - Private and Personalized Night Diving Trips in Bonaire

I didn’t connect with Sid on this trip but Martin can put you in touch with him.

Amber is still with East Coast Divers, as is Fred and and another young Dutch guide they had last year, whose name I don’t recall. On my outing with them last month they had an American named Max who freelanced with them a couple of days a week, and he was good as well. I think they are looking to hire guides full time.

I would still recommend East Coast Divers highly — it’s a well run operation even with the turnover, and the White Hole/Turtle City dive remains a world class dive by any standard, and definitely not something I would attempt from shore.

I do wonder if that is the right approach. Why if is gets worse? What if this is the final window? I'm torn between taking a break and continue to go.
 
For me, Bonaire still has a lot to offer as a low-cost, easy to access Caribbean destination with easy, convenient diving. We fly from Washington DC using frequent flyer miles, and our six trips have all been essentially free where airfare is concerned. Airbnbs are plentiful and cheap, as are rental trucks. The island topside is charming, still relatively undeveloped and not commercial. There’s good food at reasonable prices, considering that just about everything is imported. Shore diving costs about $15 a tank, if you have your own gear, which we do. You’ll see turtles, free swimming morays, and rays. You’ll also be able to see all kinds of fish behavior — porcupine fish mating, tarpon hunting, cleaning stations, etc c., and have the luxury to watch those behaviors for as long as you care to.

But there is no question that the hard corals have largely (though not entirely) died off, and I don’t see them coming back anytime soon. And the evidence of that is pretty much undeniable on every dive site on Bonaire. I took about a dozen pictures of massive brain corals, and other large hard coral colonies, that seemed surprisingly healthy, but they were absolutely the exception to the rule.

I don’t know how I’ll feel about doing a return trip to Bonaire in a year or two, but if I do return, it will be with the lowest of expectations where coral health is concerned.
