The Deering Estate is right on the bay and has stunning views of the water. You can often see manatees in the basin at the foot of the garden. there is a lovely boardwalk/nature trail plus you can rent canoes/kayaks. The house is very historic, try to take a free guided tour and learn about the secret wine cellar in the basement. They routinely have concerts/art events/festivals here so try to catch one if you can. Membership is affordable, about $65 a year for a couple and gives you access any time. Take a picnic lunch and sit under the palm trees and just chill!
