8 Incredible Day Trips from Marathon FL You Didn’t Know Existed
Marathon sits at the geographic center of the Florida Keys, which makes it one of the best base camps in the entire island chain for day trips. Within an hour’s drive (or boat ride) in either direction, you can reach ghost town islands, virgin tropical forests, one of the country’s best coral reefs, and a wildlife refuge that’s home to the world’s smallest deer. Most visitors never get past Sombrero Beach and the Turtle Hospital. These eight day trips will change that.
Quick Answer: The best day trips from Marathon FL include Pigeon Key (historic island by train), Bahia Honda State Park (best beach in the Keys), Indian Key (kayak to a ghost town), Lignumvitae Key (boat-access virgin forest), Big Pine Key and the National Key Deer Refuge, Looe Key Reef (world-class snorkeling), Long Key State Park (quiet birding and kayaking), and Islamorada’s adventure corridor.
1. Pigeon Key: Take a Train to a 5-Acre Island Frozen in Time
Pigeon Key is a five-acre island tucked beneath the Old Seven Mile Bridge, and reaching it is half the fun. You can ride a small train from the Pigeon Key Visitor Center at 1090 Overseas Highway directly across the old bridge, or walk the 2.2-mile span yourself and take in views of open water on both sides. Either way, you end up on a National Historic Landmark that once housed over 400 workers who built Henry Flagler’s Overseas Railroad between 1908 and 1912.
The guided historical tour runs about an hour. You’ll walk through original Flagler-era buildings painted in his trademark yellow, visit a small railroad museum with construction artifacts and photographs, and watch a shark feeding session (available on the 11:30 AM and 1:00 PM tours). After the tour, you have time to snorkel off the dock, fish (bring your own gear and a valid Florida license), or pack a picnic and sit under the shade of the island’s trees.
Getting there: 2.2 miles from Marathon via the Old Seven Mile Bridge. The train departs from the Visitor Center.
Hours: Daily, 9:30 AM to 4:00 PM. Tours at 10 AM, 12 PM, and 2 PM.
Cost: $30 adults, discounts for veterans, children, and Monroe County residents.
Book ahead: Call (305) 743-5999 or reserve online up to two weeks in advance.

2. Where Is the Best Beach Near Marathon? Bahia Honda State Park
Bahia Honda State Park is about 12 miles south of Marathon at Mile Marker 37, and it consistently ranks among the best beaches in the United States. Sandspur Beach stretches along the Atlantic side with fine white sand and shallow, clear water that feels closer to the Caribbean than mainland Florida. Calusa Beach on the bayside is smaller and more sheltered, which makes it a better pick for families with young children.
Beyond the sand, walk or bike a section of the Old Bahia Honda Bridge for panoramic views of the surrounding water. The park also runs snorkeling boat tours out to Looe Key Reef (more on that below). Kayak rentals are available seasonally, and birders regularly spot herons, egrets, ospreys, and the occasional roseate spoonbill.
Getting there: 12 miles south of Marathon on US-1 (Mile Marker 37).
Hours: 8 AM to sundown, 365 days a year.
Cost: $8 per vehicle (2-8 people), plus $0.50 per person Monroe County surcharge.
Pro tip: The park reaches capacity on weekends, especially during winter and spring. Arrive before 9 AM to guarantee entry.

3. Indian Key: Kayak to a Ghost Town in the Middle of the Ocean
Indian Key Historic State Park is an 11-acre island off Islamorada that you can only reach by boat or kayak. In the 1830s, this tiny island was the first county seat of Dade County and home to a thriving shipwreck salvage operation. In 1840, Seminole warriors attacked and burned the settlement to the ground. Today, the ruins of streets, building foundations, and a cemetery are slowly being reclaimed by tropical vegetation.
The paddle from Robbie’s Marina (Mile Marker 78.5) takes about 30 to 45 minutes through shallow seagrass flats. Dolphins, manatees, rays, and sea stars are common sights in the water along the way. Once on the island, a network of marked trails leads you through the historic ruins. The main boat dock is currently closed for repairs from Hurricane Irma damage, but the kayak landing is open and well-marked. Bring your own water; there are no facilities on the island.
Getting there: About 35 minutes north of Marathon by car to Robbie’s Marina (MM 78.5), then a 30-45 minute kayak paddle.
Kayak rentals: The Kayak Shack at Robbie’s Marina, (305) 664-4878.
Cost: $2.50 per person (honor system fee box on the island).
Hours: 8 AM to sunset daily.

4. Lignumvitae Key: A Virgin Tropical Forest You Can Only Reach by Boat
Lignumvitae Key Botanical State Park is one of the most unusual places in the entire Florida Keys. This 280-acre island contains a virgin tropical hardwood hammock, meaning the forest has never been logged or developed. Some of the lignum vitae trees here are estimated to be over 2,000 years old. The National Park Service designated the island a National Natural Landmark in 1968.
The island also holds the 1919 Matheson House, built by Miami chemist William J. Matheson, who powered his home with a windmill and collected rainwater in cisterns. The house is now the park’s visitor center. Ranger-guided tours run Friday through Sunday at 10 AM and 2 PM from December through April. During these walks, you’ll see rare Florida purplewing butterflies, Liguus tree snails, and Caribbean plant species found almost nowhere else in the continental United States.
You’ll need a charter boat or your own vessel to reach the island. Several operators depart from Robbie’s Marina.
Getting there: Charter boat from Robbie’s Marina, Islamorada (MM 78.5). KeyZ Charters: (305) 393-1394. Robbie’s Marina: (305) 664-4878.
Hours: Thursday through Monday, 8 AM to 4 PM. Closed Tuesday and Wednesday.
Cost: $2.50 per person visitor fee.
Guided tours: Friday through Sunday, 10 AM and 2 PM (December through April).
Website: floridastateparks.org/LignumvitaeKey
Fair warning: Mosquitoes on Lignumvitae Key are famously aggressive. Visit during winter months and bring repellent.
5. Big Pine Key and the National Key Deer Refuge: Where Miniature Deer Wander the Streets
Big Pine Key is about 25 miles south of Marathon, and it’s home to something you won’t find anywhere else on Earth: the endangered Key deer. These miniature white-tailed deer stand only two to three feet tall and wander freely through neighborhoods, pine forests, and along the roads. The entire lower portion of Big Pine Key is protected as the National Key Deer Refuge, managed by the U.S. Fish and Wildlife Service.
Start at the Blue Hole, a former rock quarry that is filled with freshwater and now supports alligators, turtles, fish, and wading birds. A short observation platform overlooks the water, and Key deer often graze in the surrounding grass. From there, hike the Jack C. Watson Trail, a short loop through pine rockland habitat that gives you a sense of what the Keys looked like before development.
Getting there: 25 miles south of Marathon on US-1 (Mile Marker 30-33).
Cost: Free.
Blue Hole location: Key Deer Boulevard, Big Pine Key (off US-1 at MM 30.5).
Hours: Refuge open sunrise to sunset daily. Visitor center hours vary; check current schedule.
Website: https://www.fws.gov/refuge/national-key-deer
Important: Drive slowly on Big Pine Key. The 25 mph speed limit exists because Key deer are regularly killed by vehicles, especially at dawn and dusk.
6. How Good Is the Snorkeling at Looe Key Reef?
Looe Key Reef sits about 12 miles offshore from Big Pine Key within the Florida Keys National Marine Sanctuary, and it’s one of the most intact sections of the entire Great Florida Reef. Water depths range from 5 to 15 feet over the reef, which means the snorkeling here is exceptional even for beginners. Expect to see parrotfish, angelfish, schools of snapper, barracuda, nurse sharks, and healthy coral formations.
Most snorkelers reach Looe Key via boat tours departing from Bahia Honda State Park marina or Big Pine Key operators. The Bahia Honda concession runs regular reef trips that include gear rental. Several private charters out of Marathon will also take you to Looe Key.
Because the reef is protected, the water clarity and marine diversity are significantly better than at unprotected sites. The reef is named after the HMS Looe, a British warship that ran aground here in 1744, and you can still see remnants of the wreck scattered among the coral.
Getting there: Boat tour from Bahia Honda State Park marina or Big Pine Key operators. Also available from Marathon-based charters.
Cost: Varies by operator. Bahia Honda snorkel tours typically run $30-$45 per person.
Water depth: 5-15 feet over the reef.
Best conditions: Calm days with good visibility, typically spring and early summer.

7. Long Key State Park: The Quietest Spot in the Florida Keys
Long Key State Park at Mile Marker 67.5 is only about 20 minutes northeast of Marathon, and most visitors blow right past it on their way to Islamorada. That’s exactly what makes it special. This 965-acre park occupies an island that was once the site of Henry Flagler’s Long Key Fishing Camp, a luxury resort that attracted celebrities and presidents before the Labor Day Hurricane of 1935 destroyed it completely.
Today, the park is one of the quietest spots in the Keys. The 1.2-mile Golden Orb Trail winds through five distinct natural communities and ends at an observation tower with a panoramic view of the island. The shorter Layton Trail on the bayside takes about 15 minutes and passes through mangrove habitat. The park sits on the Great Florida Birding and Wildlife Trail, and patient visitors can spot herons, egrets, white-crowned pigeons, and roseate spoonbills.
If you bring your own kayak, you can paddle through a mangrove-lined lagoon near the ranger station. Kayak rentals are currently suspended.
Getting there: 20 minutes northeast of Marathon on US-1 (Mile Marker 67.5).
Hours: 8 AM to sunset daily.
Cost: $4.50 for a single person; $6 for a vehicle with two or more people, plus $0.50 per person.
Trails: Golden Orb Trail (1.2 miles, ~40 minutes) and Layton Trail (0.25 miles, ~15 minutes).

8. Islamorada’s Adventure Corridor: Tarpon Feeding, Fossil Reefs, and Theater of the Sea
Islamorada is about 30 minutes north of Marathon, and while it’s no secret to anyone who’s driven the Overseas Highway, most people only stop at Robbie’s Marina to feed the tarpon and then move on. That’s a mistake. Islamorada packs more variety into a short stretch of highway than almost anywhere in the Keys.
Start at Robbie’s Marina (MM 78.5), where you can hand-feed massive tarpon from the dock for a few dollars in bait. From there, rent a kayak and paddle to Indian Key (see trip #3 above) or take a boat tour to Lignumvitae Key (trip #4). But here’s what most people miss:
Windley Key Fossil Reef Geological State Park (MM 84.9) is a former quarry that exposes cross-sections of ancient coral reef dating back 125,000 years. You can walk through the quarry walls and touch fossilized brain coral, star coral, and conch shells embedded in the limestone. It’s a geology lesson you can’t get anywhere else in the Keys. Open Thursday through Monday, 9 AM to 5 PM. Admission is $2.50 per person.
Theater of the Sea (MM 84.5) has been running marine animal shows and swim-with-dolphin programs since 1946, making it one of the oldest marine mammal facilities in the world.
Getting there: 30 minutes north of Marathon on US-1 (Mile Markers 74-85).

What’s the Best Day Trip from Marathon for Families?
For families with young kids, Bahia Honda State Park and Pigeon Key are the two strongest picks. Bahia Honda has calm, shallow water at Calusa Beach and the park infrastructure (restrooms, concessions, shade) to support a full day. Pigeon Key works well because the train ride is an adventure on its own, the guided tour is engaging for older kids, and the shark feeding is a highlight for all ages.
For families with teenagers, add Looe Key snorkeling and the tarpon feeding at Robbie’s Marina.
