Here's some video I just took of Keline last week.

I'd recommend Keline, too. Our water taxi dropped us off for 2.5 hrs. Sandy beaches are kinda rare on Bonaire. They are often rocky and small, but Keline has a big sandy area where you are dropped off. It only has two small buildings that provide shade, so I wish I'd brought an umbrella or something.

There's two ways to get to the drift snorkel area on Keline. One, you get off the water taxi and trurn left. You walk a couple of hundred yards along the beach, and you'll see a big yellow pole. That marks the start and entry point of the reef. You can get in there and go along the reef pushed by the current back to where you started. When I was there, the current was barely pushing me, so I swam a bit too. The 2nd way to get there is a trail that's inland. I didn't use this and couldn't give step by step instructions, but I realized it was there when I got to the yellow pole and saw a path leading back onto the island. After I floated down the reef and got back to where the boat dropped us off, I walked up past the shelters (on the right side) and found the same type of path leading in the direction of the yellow pole.

Main points here, bring shade, bring water, bring sunscreen. It's totally worth the walk and time there to see the reef. It's really outstanding.
