We did Boka Slagbai and Bise Morto our first trip to Bonaire many years ago. Did not care for Boka Slagbai but loved Bise Morto. Would love to dive Bise again as a 2 tanker but the required drive through the park has stopped us from returning. In fact we haven't been back to the park since out first time. It may not always be that way but the road was so bad that there were some ruts that we almost got lost in. We were genuinely concerned the car might not survive the trip!
Thanks for the feedback. We've been lucky with the park roads I guess, it never even took close to as long as they said it would to drive around the sites.
