Overview
Guanaja is the least built-up of Honduras' three Bay Islands, and that remoteness shapes the trip in all the right ways. You come for steep reef walls, pinnacles, lava-cut swim-throughs, and wrecks like Jado Trader, but also for the sense that you have reached a place where boats still matter more than roads. The island sits inside the Bay Islands National Marine Park, with BICA Guanaja helping patrol and protect the reefs. Underwater, Guanaja blends deep blue wall diving with easy shallow history at George's Wreck and house-reef snorkeling around Dunbar Rock. Above water, Bonacca, Deena Beach, waterfall hikes, and low-key resort life make it work for mixed groups. It is not the easiest Caribbean trip logistically, but for divers who value quiet, variety, and healthy reef structure, that is exactly the point.
Guanaja sits inside the Bay Islands National Marine Park, Honduras' largest marine protected area, with local BICA patrols helping protect reefs, fisheries, and mangroves.
You can combine volcanic canyons, wall dives, pinnacles, shallow snorkel terraces, and wrecks like Jado Trader and George's Wreck in one trip.
Compared with the busier Bay Islands, Guanaja remains quieter above and below water, so many dive days feel uncrowded even in prime season.
Transfers, sightseeing, and daily life still revolve around the water, which gives the island a distinct maritime rhythm and a stronger sense of remoteness.
