Long Key, Florida: Best Things to Do – Top Picks

Did you know Long Key was once home to one of Henry Flagler’s most luxurious resorts, attracting wealthy travelers who arrived by train to enjoy its pristine beaches and exclusive atmosphere? Today, this hidden gem in the Florida Keys offers a perfect blend of natural beauty, outdoor adventures, and peaceful relaxation away from the crowds of more popular Keys destinations.

Getting There & Planning Your Journey

Long Key sits approximately halfway down the Florida Keys island chain, making it an accessible destination whether you’re coming from the mainland or Key West. The closest major airports are Key West International Airport (EYW), about 67 miles southwest, and Miami International Airport (MIA), roughly 100 miles northeast.

Most visitors reach Long Key via the Overseas Highway (US-1), the iconic road that connects the entire Florida Keys archipelago. The drive itself is part of the experience, with stunning ocean views on both sides as you cross numerous bridges between islands.

For the most flexibility during your visit, consider renting a car at your arrival airport. This allows you to explore Long Key and neighboring islands at your own pace, which is particularly valuable since public transportation options are limited in the Keys.

Best Time to Visit & Weather Tips

The ideal time to visit Long Key is during the dry season from November through April. During these months, you’ll enjoy temperatures averaging 21-27°C (70-80°F), low humidity, and minimal rainfall. December through February offers the most comfortable conditions, though water temperatures might be slightly cooler for swimming.

The summer months (June through September) bring higher temperatures around 32°C (90°F) and increased humidity. While you’ll find fewer tourists and lower accommodation rates during this period, be aware that hurricane season officially runs from June through November, with the highest risk between August and October.

Getting Around Locally

Long Key itself is relatively small, spanning just over 2.5 km (1.6 miles) at its widest point. The main attractions are concentrated around Long Key State Park and along the Overseas Highway. Here are your best options for getting around:

• Car: The most convenient option for exploring Long Key and venturing to neighboring islands
• Bicycle: Perfect for leisurely exploration of Long Key State Park and its trails
• Walking: Feasible within specific areas like the state park trails and beach areas
• Kayak/Boat: Great for accessing coastal areas and nearby waters

If you’re staying on Long Key for your entire trip, you might not need a car every day. Consider renting a vehicle for just part of your stay to explore other Keys, or use local tour operators for excursions.

Where to Stay

Long Key offers a range of accommodation options, though they’re more limited than in larger Keys destinations like Key West or Marathon. For the best experience, book well in advance, especially during the peak winter season.

For a truly immersive experience, consider accommodations that offer water access for kayaking and fishing, or properties with sunset views over the Gulf of Mexico.

Dining & Local Cuisine

While Long Key itself has limited dining options, you’ll find excellent restaurants within a short drive in either direction. The Florida Keys are known for fresh seafood and tropical flavors, with these local specialties you shouldn’t miss:

• Fresh-caught fish (mahi-mahi, grouper, snapper) prepared grilled, blackened, or fried
• Stone crab claws (in season from October to May)
• Conch fritters and conch chowder
• Key lime pie – the official dessert of the Florida Keys
• Cuban-influenced dishes reflecting the region’s cultural heritage

For picnics at Long Key State Park, stock up on supplies in Islamorada or Marathon. Many vacation rentals offer kitchens where you can prepare your own meals with local seafood purchased from markets along US-1.
