HI Paddy,

De Leon Spring is a nice day trip. North on I-4 until you follow signs for De Land (nice old fashioned town) to stop off and browse around on the way.

The De Leon Spring Nature Park itself was great you can swim / take a boat trip / and - a bonus as far as I'm concerned - your choose own fillings and make your own pancakes at the table in the Sugar Mill restaurant on site if/when the weather turns bad.

Also,privately owned Bok Tower Gardens is another nice relaxing afternoon trip down the 27 South (sign posted)near Lake Wales. Pretty gardens/tower with carillion music (mostly recording) played 3.00pm everyday and on the hour.
