Parking in Key West is at a premium as the island is small and very popular. Here are a few suggestions which should help.
Old Town Parking Garage at 300 Grinnell St. Approx $13 per day
201 Simonton Street. A privately run parking lot 2 blocks from the house. They charge $20 per day mid week but this increases to $25 for weekends.
408 Caroline Street. As above with similar charges.
Parking Meters are 25 Cents for 10 mins or $1.50 per hour and are limited to a 3 day maximum.
The neighborhoods of Old Town offer some free parking spaces but be aware that many of these spots are marked “Residents Only” and visitors are NOT permitted to park in them.
