The entry's in Bonaire can be easy or ankle breaking, depends on the site, how much gear you are carrying, if there is any surf (rarely if you are diving on the leeward side). Be sure the boots will support your ankles and have a solid tread, soft malleable tread is bad. If you are using a stage cylinder it will be best to take it and your fins to the waters edge, then go back for the BC/tank, scope out your entry when you drop your fins and plan how you want to get in. Many sites will have a specific marked spot for entry, look for the painted rocks, not only at the road, but at the waters edge too. Take a local if you can. Keep your hands off the reef, many sharp things there and gloves will get you a ticket from the scuba police. Another very annoying thing about Bonaire is the theft problem, you MUST leave your vehicle unlocked and with absolutely nothing inside. Really! The car rental places will charge you for broken windows and if you leave the doors locked, your windows WILL get broken. The diving there is spectacular, great reefs and lots of fish, but the best dive sites are the farthest north and south of town. Out by the salt piles and north of the fuel storage tanks have the best sites. Be sure to see the Helma hooker site. have fun!
