The outer atholls have the best diving in my opinion. I've been to Glovers Reef about 5 times on the south tip. Marisol Resort.
I have been to the Elbow of Turneffe....lots of times...more than 40 I guess. Really nice and a very fishy spot on a world scale. One of the best if you want to see mass schools of snapper, jacks, spadefish and big grouper on the bottom. Sometimes it's easier to see the fish free diving. Scuba bubbles seem to scare them off sometimes, I would guess because workers at the resorts go out in the evenings and shoot fish for the guests using scuba. Snappers are really smart.
I've dived Lighthouse a couple times but only the BH and the south. But there is a resort there. I would guess it's "all time" diving also.
I live and dive around the reef 10 miles north and up to 20 miles south of Dangriga area. Not many dive shops come to this area at all. But we have a lot of cuts on the reef and lots of fish too. If you want to dive this area, there are resorts on Tobacco Caye, Southwater Caye, Thatch Caye and the Hopkins Village area. Hamanasi, Jaguar Reef ...to name a couple resorts.
