I had a good time diving at El Dorado. The basic accommodations weren't that exciting but the house reef was good. 4 different color anenomes, hairy froggy, nudibranchs, peacock mantis, big green and huge hawksbill turtle that hung out the entire week we were there, garden eels, morays, grunards, xenos tons of peterson shrimp and huge schools of grunts and cardinal fish. I also saw a few larger fish stopping by to get cleaned one day. I'd rate the diving right off the beach as an A if you're into macro. Viz was 40ft on a good day. The entire area gets a lot of rainfall and the grade is very steep so run off is quick. On rainy days you could find yourself in 15ft visability and the shooting got tough even for macro.
The food was outstanding but you had to compete with a lot of flies. Most (all?) of those resorts lie in rural Dumagette where folks raise their own chickens etc. The staff does a pretty good job of trying to keep them away but there were so many it was a full time job.
The famous Ducom Pier is a short van ride from the resorts and is the highlight of diving. Diving here is great for both WA (soft corals, schools of fish) and macro. There's probably every type of nudibranch and frogfish you could want right under the pier. Amid pier legs encrusted with the most beautiful soft corals I've ever seen.
Bottom line - I'd give my left kidney to go back tomorrow but I'm all about what is under the water and will rough it up top. If my wife wasn't a diver, I'd have to consider doing Puerta Gularta (had friends who stayed with us at El Dorado and at Puerta and said the accommodations at Puerta were much better) and do my diving in secret bay. You could, and should, do an overnight to Dumagette if possible. The pier is not to be missed. Most, not all, of these shots are from the house reef and the Ducom Pier Dumagette Photos
