Slickrock retreat on Long Caye is about as rustic a place as I think I could feel comfortable. The cabanas, located just feet from the surf, are bare-bones thatched-roofed shacks with plank bed(s), a couple of rough benches and shelves, hanger rack, and a fluorescent light. No air conditioning, and if the wind is not in the right direction they can be uncomfortably hot when the humidity and temperature are high. The outhouse (two composting toilets) is clean. The outdoor showers, surrounded by walls for privacy, use well water warmed by the sun, so the temperature depends on the time of day and the weather conditions. The well water is salty (though less so than the sea) so you never feel really clean.
That's the bad stuff. And that's the only bad stuff. It's important to know that the conditions are intentionally rustic. Very rustic! But if you like rustic, or you don't mind rustic, this place is paradise.
The activities are all detailed on their web site, and include sea kayaking, snorkeling, wind surfing, kayak surfing, lounging around, and exploring the intertidal flats at low tide. Slickrock shares the island with Off The Wall Dive Resort, so scuba diving is also an option, including "Discover Scuba" for first-timers and full certification classes. I got my PADI Open Water certification there and it was a blast! (Because the dive resort is a separate business, you must pay separately for diving. Rates are on Slickrock's web site, as well as the dive resort's own web site.)
One of the best things about Slickrock, and one of its distinctive features, are the guides, who provide complete instruction in all the activities, from beginner to advanced level, at no additional cost. And they are absolutely first-rate.
I cannot be as enthusiastic about the food as some of the other reviewers. I have been at places where the food was really fabulous. However, the food at Slickrock was good, and it was plentiful. I was never disappointed by it.
While some folks preferred the above-water sports, what I found really spectacular was the world under the surface of the ocean. The numerous spot reefs were brilliant in their diversity of color and form, and were teeming with marine life. I never cease to be amazed by the corals and the fishes. And if you choose to don scuba gear, there is a wall of coral that starts at about 40 feet and goes down deeper than you can dive. Apparently there are a hundred sites all claiming to be the second-best diving/snorkeling reefs in the world. But Long Caye is certainly one of them.
A regular activity was "paddle to snorkel." At the start of your stay, the guides will teach you how to get into and out of a kayak in deep water, and how to empty and right a kayak that has turned over and flooded. After that there are many opportunities to paddle to the many spot reefs for snorkeling. Distances range from 5 or 10 minutes to perhaps 20 minutes or so. There are also longer kayak journeys available.
If you like warm-water snorkeling or diving, and you like rustic (very rustic!) you should not miss the chance to visit Long Caye.
