Fly, worth it for many reasons.

There are Taxi's when you get out of the plane that will take care of you, only about 9 taxi's on island. They will take care of you, drop you off and pick you back up where ever as well as give you suggestions.

The only hike we did was to the top and back down. It is not an easy stroll, the stairs get tiring both up and back down but the view was worth it.

We did a single night over there at Queen's Garden, besides the hike it was one of the more relaxing places I have been. We did the hike just after arrival, had a nice dinner that evening and then sat around the pool area the next day until time to go.

Enjoy your trip!
