To get to know Curacao better, take island tours from the tour operators or taxi cabs. Both do excellent jobs on sightseeing.

Taxis are good for small groups, up to 12 persons. Especially groups of family and friends.
Sightseeing Tours with taxis are more flexible, you can arrange your pick-up time and not the usual 9AM. And the tour is more private. It's almost like a VIP tour.

Another great way to get to know the island is via the tour operators. They have great tailor-made tours for everyone.
But you must know that not all of them are wheelchair accessible.  

Of course there are also those jeep safaris, quad trips and such.  Several tour operators offer day trips to Klein Curacao, something every tourist must do if they have the time.
