Encompassing about 70 nautical square miles, the John Pennekamp Park was the first recognized undersea park in the US. Its northernmost edges border the Everglades and the mangrove swamps. However, most people come to see the coral reefs and their associated sea life, which makes up most of the park.

Visitors can book a seat on the glass-bottomed boat or hire snorkel or dive gear to fully experience the underwater attractions. A wonderful place to share with families, groups, and friends. Book tours online here.

You can find tours that include the rental of fins, vests, and snorkels – one of our favorite tours is this one that also includes snacks and drinks.

Most tours last between 2-3 hours, and you are guaranteed to have a great time and see some amazing marine life. The impressive coral formations and diverse sea life mean time will fly by.  You are sure to love your time snorkeling with all the fish. Great fun for families, couples, and groups.

Located 6 miles off of Key Largo lies the shipwrecked Spiegel Grove dive site. Intentionally sunk in 2002 to form a new reef, the Spiegel Grove was one of the biggest examples found in the world. For many divers, the site boasts some of the best coral and sea life to be found in the Florida Keys.

Colorful tropical fish, large groupers, and schools of small silverfish can be found in abundance. The dive, like most wreck dives, is not for beginners or inexperienced divers. Log-book proof of sufficient open-water dive experience is required by all reputable dive operators.

Apart from diving and snorkeling, there are also various deep-sea fishing charters in Key Largo. If, like me, you enjoy the idea of an extreme, fun-filled fishing adventure, then this is for you.

Many operators use different fishing techniques to catch a wide variety of fish. A great day out on the water for children, families, small groups, and business travelers alike. There are fishing charter options for a few hours up to the whole day.

7. History of Diving Museum

We almost skipped this spot, but it ended up being actually really neat. The History of Diving Museum is another not-for-profit, independent organization that ‘preserves, educates, and exhibits’ everything to do with diving. They focus on the Florida Keys in particular and always have new and constantly evolving exhibits and presentation talks.

The exhibits also show the entire history of diving equipment, from ancient methods to cutting-edge modern dive equipment. An interesting visit for all ages and groups. Even if you aren’t a diver, it’s still a unique thing to do in Islamorada. Adult tickets are $15, but mention you saw a $2 off coupon on their website.

8. Everglades National Park

The Everglades National Park is the largest protected area of subtropical wilderness in the United States. If you really want to get the most out of your visit consider a guided tour. We suggest this Everglades National Park airboat tour. With an expert guide, your chances of seeing a manatee or American crocodile are a lot better, but you will definitely leave with a better understanding of the park.

Even though you might not see the rare Florida panther, you are sure to have a one-of-a-kind experience. Hugely enjoyable for everyone and at the same time educational too.

9. Florida Keys Brewing Company

Although the name would suggest this location could only appeal to over 21s, then, like me, you would be surprised to find how child-friendly the FKBC is. Here you’ll find a charming beer garden with some green space for kids to have a little fun while parents can partake in some local craft beer.

Florida Keys Brewing Company is a great place to visit if you’re a microbrewery lover. Plus, they have lots of live music events thrown in for free!  For the serious beer connoisseur, there is also a tour of the microbrewery available.

  • Address: 81611 Old Highway, Islamorada FL (Beer Garden and Tasting Room)

Marker 88 is a bar & restaurant on Islamorada and gains its moniker from the mile marker of the same number on the Overseas Highway. Stop by for some drinks and relaxation with the spectacular view across Florida Bay and out to the Gulf of Mexico. Stay for dinner and sunset at the on-site restaurant with nice westward-facing views.

Mile Marker 88 is a must-visit stop for us every time. It is. a great place to get out and stretch your legs if you are driving from Miami to Key West, even though we suggest spending the night or two along the way.

11. Stay at Jules Undersea Lodge

12. Feed the Tarpon at Robbie’s

Down the road, a few miles from Key Largo, is Robbie’s on Islamorada. Here at Robbie’s, if you dare, you can dangle a little fish over the edge of the dock, and within seconds a giant tarpon will come and snatch it. If you get low enough and don’t let go, you’ll find your whole hand inside the massive toothless mouth of a tarpon. Tarpons are huge, and there is a school of Tarpons with more than 100 of them here at Robbie’s. Click here to learn more about Tarpon fish.

The price to feed the tarpon is $4.50, and this gets you a bucket of minnows and a place in the queue on the pier. You can also enjoy lunch at the onsite restaurant, and from a distance watch, others hang their hands out as fish bait and wait for the occasionally surprised yelp. It’s a fun way to spend a few hours and have lunch while visiting Key Largo and Islamorada. The less courageous can just watch the feeding close-up for a fee of $2.50.

13. Harry Harris Park & Beach

In addition to the white sandy beach, Harry Harris Park boasts multiple facilities and activities. Along with public restrooms with showers and parking facilities. Hiking and biking trails thread through the beautiful natural backdrop of the park.

Nature lovers can be delighted in spotting rare tropical birds or even sighting an African rainbow lizard. The beach is ideal for families, especially those with smaller children. It is very calm and safe for children as the tidal pool is protected from all sides. There are two playgrounds for kids, so those that don’t love the water can still have fun.

If you are up for a barbecue, there are plenty of grills available alongside fire pits and picnic tables. We like to pick up lunch to go to one of the best restaurants in Key Largo.

14. African Queen Canal Cruise

If you haven’t seen the movie The African Queen, then this attraction might seem a little odd. However, if you know the work of Humphrey Bogart, then you would understand the connection. Two seminal films with the famous screen actor were Key Largo and The African Queen. Every year there is a celebration of Bogart’s career and The African Queen plays a big part in that festival.

In 1992 the boat became a registered National Historic Site and was lovingly restored in 2011 for its centennial birthday in 2012. Booking is made online, and a tour along the canals lasts about an hour and a half. There are also dinner and lunch cruises available for groups of 4 or more.

The captain I had was exceptionally friendly and engaging. His knowledge of the film was profound, and I learned a lot I didn’t previously know.  It was also interesting to see the different styles of Floridian canal houses as we ‘steamed’ along. Drinking water was provided, but they recommended bringing food and beverages as we wanted. Definitely a fun excursion for all the classic movie lovers out there like me.

15. Sunset at Sundowners

Since 1985 Sundowners Restaurant has been providing unparalleled views and dining experiences for guests. Serving some of the freshest and best seafood in Key Largo, diners can also take pleasure in their surroundings.

The glass-walled dining room allows amazing views out to the Gulf of Mexico across Florida Bay. Outside, large Tarpon fish swim right up to the tables on the edge of the covered deck, and guests can even feed them.

If all of that wasn’t enough, there are live music events throughout the year. All of the food we ordered was cooked exceptionally well, and everything (including the ribs) was delicious. Watching the glorious sunset on our last day in Key Largo and sharing great food made this trip a memorable one.  Highly recommended for all groups and families. Click here to check out their menu.
