Natasha:
I agree with Bob! The best way to do the Hilma Hooker and others including Karpata would be by boat.
We rented a jeep just one of the days to play around the island.
Given everyone has their own preference, I just can't agree with this one.
I spent two weeks in Octoder there and never stepped on a boat. All dives were from shore including the Hilma, Karpata, and many others that that I never got around to on my first trip. I was lucky to have a buddy that knew all these sites are easily done from shore(experienced with Bonaire) and we both remarked every day about the dive boats at these sites and wondering why people would spend money on a charter to a location they could access from shore. If you want to dive from a boat, yes, go to Klein. Don't waste boat charters on west side dives that are, in actuality, just as easy to do from shore. In fact, what you may find in the shallows during that swim back to the exit is some of the most exciting and interesting u/w life of the entire trip. Seen it!
Natasha, Bob, your views may differ and I understand, but for those that are going to Bonaire for the first time, I felt they should know that the options are larger than when and where the boat is going. Klien is great and should be done(kicking myself for not getting out there this time around), but by no means is a boat IMO the way to get to sites that are considered, by most, easily accessable from shore. I could be wrong, but the the 48 dives I logged at darn near every site on the west side says I have a point.
And the bottom line...Dive Safe!

PS: some pics I took that I would have missed if I had to board a boat. All of these pics were taken in the shallows where most boat divers never see.
