wooden fishing vessel, the kind Ernest Hemingway once patronized.

Next door is the Islamorada Fish Company, a popular seafood
restaurant and tiki bar that is part of the Worldwide Sportsman
complex. Besides dining, you can buy fresh fish here, just off
the boat. The restaurant has its own fishing fleet. There is
also a restaurant and bar inside the main store.

wooden fish shack built in 1947, a good place for breakfast,
lunch or dinner, with outdoor seating overlooking the marina.

Calusa Cove Marina.
Boy Scouts Sea Base, gulfside; Calusa Cove Marina. Oceanside.
Gulfside was the location of Camp 3 for WW-I veterans. Many

Anne’s Beach, Oceanside. Anne’s beach is a lovely, sandy free
beach, so shallow you can wade out great distances. The shore is
lined with mangroves, through which a boardwalk, with periodic
picnic tables, weaves. Anne’s Beach has limited parking and is
very popular. If you can get a space, it makes a nice 20 minute
stop in your roadtrip to wade in the shallow water.
Channel 2 Bridge. Off shore on the bayside can be seen the
remains of eight concrete bridge pilings built by the WW-1
veterans. Excellent fishing off the bridge in the channel.
Channel 5 Bridge. Considered by locals to provide the best
bridge fishing in the Keys on the old bridges, which extend
from both ends of the new bridge. Plenty of paved parking and access.
Long Key State Park, Oceanside. It’s hard to find a more
scenic camping spot anywhere. At Long Key, campers can set
up right on the beach. The park is popular for its beach,
kayaking and fishing.

outside of Long Key State Park. Drop your kayak over the
Fiesta Key RV Park and Marina.

Grassy Key, Dolphin Research Center. The focus of this
not-for-profit facility is on education. Rather than
choreographed shows, trainers hold informative sessions
as visitors stand on the dock around open-water tanks.
Many ways to interact with dolphins are available for an extra fee.
Curry Hammock State Park offers swimming, a playground,
picnic tables and some of the most sought-after camp
sites in the Keys. Day visitors can launch kayaks from
the beach and paddle coves and trails. There’s a 1.5-mile
nature trail for hiking, and you can bike along the
Florida Keys Overseas Heritage Trail.
Entrance to Village of Key Colony Beach, Oceanside.
Take the Sadowski Causeway/6th Street to the end and turn
right on W. Ocean Drive for the Key Colony Inn, one of the
best restaurants in the Keys. Prices are moderate and the
seafood selection outstanding. Truly, a hidden gem off the
beaten path. The same causeway passes another good
waterfront seafood bar and restaurant, Sparky’s Landing,
which has indoor and outdoor seating and live music.
Island Boat Ramp. Public boat ramp adjacent to
The Island Fish Company Tiki Bar & Restaurant, which is
also a great place to eat and drink. It has the longest
covered tiki bar in the Keys and is ideal setting for watching sunsets.

next 8 miles.
Marathon County Airport, bayside
Crane Point Museum and Nature Center, gulfside.
Admission: Adults $12.50, children 5-13 $8.50 and 4 and under free.
Sombrero Beach. There are few “real” public beaches
in the Keys, and this is one of them. Turn south at the
light (Publix Shopping Center) and follow Sombrero Beach
Road to the end. Plenty of parking.
The Stuffed Pig. Bob’s favorite breakfast destination
The Turtle Hospital. Located in a former motel bayside
on the Overseas Highway, the Turtle Hospital supports its
program of rescuing and rehabilitating about 100 injured
sea turtles a year through the admission price paid by visitors.
A 90-minute educational tour is given several times a day.
Visitors meet the injured sea turtles up close and get to
throw some feed into their tanks.
Turnoff to Chiki Tiki Bar and Grille at Burdines Waterfront,
one of the best casual restaurants and tiki bars in the Keys.
To find it, you turn east on 15th Street in Marathon, wind
past an old trailer park and stacks of lobster traps, and
arrive in a large working marina in a protected harbor.
The Chiki Tiki is up a flight of stairs, giving you an
excellent vantage point and a breeze.
Porky’s Bayside BBQ and Captain Pip’s Marina & Hideaway,
the place to be in the 1950's when it was known at Bill
Thompson’s Villas and Marina. Such notables as Ernest
Hemingway, Jimmy Hoffa, Elizabeth Taylor and Eddie Fisher
were regular visitors. Reviews on Yelp! and Trip Advisor
are quite complimentary, with special kudos for the atmosphere
and tasty barbecue dishes.
Seven Mile Grille. Outdoor eatery at the foot of the
Seven Mile Bridge in Marathon. A landmark serving
“Keys food.” Breakfast and lunch menus are reasonably prices
and you can’t beat the sunset view during happy hour.
We included Seven Mile Grille in our wrapup of Keys tiki bars.
Knight’s Key Campground. Oceanside. There are 192 RV sites,
some waterfront with dockage, and prime location at the
foot of the Seven Mile Bridge. Many amenities nearby,
as well as the “old bridge” and Pigeon Key. For reservations,
call (305) 743-4343.
East end of Seven Mile Bridge. Access to bridge is gulfside.
Pigeon Key visitor’s center is oceanside. Here’s another
road-trip must-do: You have to get out and take a stroll
on the bridge. Here’s more about walking or biking the
Old Seven Mile Bridge.

Veterans Memorial Park. This small, free oceanside park just south of
the Seven Mile Bridge is a great place to stop for a picnic or to use
the restroom. Picnic tables are under chickee huts, there’s a beach
where you can wade or swim and palm trees lean like they are waiting
to be captured in a postcard. It’s also an easy kayak launch.
If it’s crowded, there’s also a large parking area and a small
boat ramp bayside.
Missouri-Little Duck Channel Bridge
Ohio-Missouri Channel Bridge
Sunshine Key RV Resort and Marina. Crowded in winter.
Ohio-Bahia Honda Channel Bridge
Bahia Honda State Park entrance, oceanside. In my view, Bahia Honda is
the best of the state parks in the Keys. It offers a great beach and
snorkeling, good kayaking and the old camelback bridge is an awesome
sight up close. On top of that, there are campsites and several
well-equipped, reasonably priced cabins. Of course, campsites and
cabins book up many months in advance, so plan ahead to stay overnight.
Book your campsite reservations through Reserve America.
Bahia Honda Bridge (4-lanes); you can view the old railroad camelback
bridge on the oceanside.
