Very large beautifully laid out gardens,150+ acres. Good free transport around the garden nice structures (arbors, seats etc) to relax and rest. Themed garden, e.g. roses, Japanese, sensory etc. Much water on the property to add to interest. A water trip/ride available at extra cost. Admission very reasonable, nice gift shop.
The garden is just by the airport, and they have an aviation display on the embankment with a place to sit down and watch the ground operations of the airport. Worth a visit.
