This 11-hectare (27-acre) public garden opened in 1998, using the former grounds of a long-gone estate. The designers incorporated the existing high hedges and trees, and have ambitiously planted open space around the mature plants. The project has become a noted stop for garden lovers. The grounds include almost 2,000 varieties of trees (including old-growth forest), shrubs, and plants. Among the notable features: a day lily collection, an extensive rose garden, a small maze, a fully functional Dutch windmill that circulates water through the two duck ponds, and a children’s garden with an elaborate Victorian-mansion playhouse. With views over the lush lawns to the bay below, the on-site Garden Cafe is a pleasant place to stop for lunch. (Try the thick, creamy seafood chowder and one of the focaccia bread sandwiches.) There’s also a gift shop and art gallery. Those with a horticultural bent should plan to spend at least a few hours here.
