The good: Being our first time on the island, we didn't want to fall into the typical traps and we weren't disappointed. The restaurant reviews were very helpful in avoiding bad service, value and food. The infinity pool over the falls was one of the most exciting and exhilerating places I've ever had the privilege to visit. While everyone was going left at the fork to the bamboo forest (we went there after), we took the right. Lo and behold a paradise within paradise. That experience paid for the book in itself!
The bad: Not much really, except that we almost got ARRESTED at the Aquarium at La Perouse Bay! Little did we know that 15 days before our visit the entire La Parouse sanctuary was changed from a park to a reserve...with rangers/wardens. We did actually make it all the way to the Aquarium bay and chose NOT to go in the water even though we had our snorkeling stuff with us as we did not feel right destroying the coral to get in. Second to only the Infinity Pool for excitement, the bays near the Aquarium were unbelievable and LOADED with fish. Crabs were actually scattering away as we were walking in that lava wasteland and if you put your hand in the water you could probably touch 5 fish in one swipe they were so plentiful. 5 minutes later the ranger showed up in camo pants(pretty sure the only guy I saw on the entire island with pants) and floppy hat to whisk us away! After a very stern warning, taking our picture, etc, he let us go. Supposedly up to a $1000 fine each and up to a year in jail, so don't mess around at the site people, unless you are very stealthy. I'm pretty sure they/he saw us from La Perouse point itself across to where we were at the first bay, so plan accordingly if you're feeling brave or go the back route, further north.
My advice after 12 days of paradise with this book? Buy it now, but THINK before following the advice, especially when your life could be in the balance(infinity pool with high flow conditions, swimming out in certain spots like the black sand beach, etc). Ultimately, it's always the user of any device or place that needs to be aware of dangerous surroundings and plan accordingly.
