Best Sunset Spots in Marathon & the Florida Keys

There’s a reason people in the Florida Keys stop what they’re doing to watch the sun go down. The combination of flat horizons, warm Gulf water, and wide-open sky produces sunsets that look almost unreal — deep oranges bleeding into pinks and purples, reflected across the water in every direction. In Marathon, where the Gulf of Mexico sits on one side and the Atlantic on the other, you get front-row access to this show every single evening.

Here are the best spots to catch a sunset in and around Marathon, whether you want a quiet beach, a waterfront restaurant, or a view from the water itself.

Sunset Park, Key Colony Beach

Ask any local where to watch the sunset in Marathon and they’ll almost certainly point you to Sunset Park on Key Colony Beach. This small waterfront park at the southwest corner of Key Colony faces directly west over the Gulf, with unobstructed views of the horizon. There are benches, picnic tables, and a small dock where you can sit and watch the sky change.

What makes Sunset Park special is the community ritual. Most evenings, locals and visitors gather with drinks, snacks, and their dogs to watch the sun go down together. You’ll often hear music playing, and a group of regulars sometimes sings as the last sliver of sun disappears. It’s not a formal event — it’s just something that happens, and it’s one of the most authentically Keys experiences you can have.

Tip: Parking is limited, so arrive 20–30 minutes before sunset. It’s about a 10-minute drive from Blackfin Resort.

The Old Seven Mile Bridge

The historic Old Seven Mile Bridge is open to pedestrians and offers one of the most dramatic sunset vantage points in the entire Keys. Walking out over the water, you’re surrounded by ocean on all sides with a nearly 360-degree view of the sky. As the sun drops toward the Gulf, the light reflects off the water in every direction, creating an effect you simply can’t get from shore.

It’s also a favorite spot for photographers. The old bridge pilings, the sweep of the new bridge in the background, and the open water make for stunning compositions. You don’t need to walk far to get the views — even a few hundred yards out feels like you’re standing in the middle of the ocean.

Tip: The bridge is about a 5-minute drive from Blackfin Resort. Bring water and wear comfortable shoes if you plan to walk a longer stretch.

Sombrero Beach

Sombrero Beach is on the Atlantic side of Marathon, so it faces south and east rather than directly west. That means you won’t see the sun sink below the horizon from here. But what you do get is the afterglow — the sky behind you turns brilliant shades of orange and pink that reflect off the calm water in front of you. It’s a different kind of sunset experience, quieter and more subtle, and the soft sand, palm trees, and picnic pavilions make it a beautiful place to end the day.

Sombrero Beach works especially well for families. The kids can play on the beach while you watch the colors change. Free parking, restrooms, and showers are all on site.

Bahia Honda State Park

About 15 minutes west of Marathon, Bahia Honda State Park has some of the most beautiful beaches in the Keys and west-facing views that are ideal for sunsets. The combination of white sand, clear shallow water, and the remains of the old Flagler Railroad bridge creates a setting that looks like it belongs in a travel magazine. It’s one of the most photogenic sunset locations in all of South Florida.

Tip: Bahia Honda has an entrance fee (currently $8 per vehicle with 2–8 occupants). During peak season, the park sometimes reaches capacity and closes to new visitors, so plan to arrive early if you’re making a day of it.

Pigeon Key

For a more intimate sunset experience, Pigeon Key is a tiny five-acre island accessible by ferry or by walking the Old Seven Mile Bridge. The island is a National Historic District with restored buildings from the early 1900s, and the sunset views over the surrounding water are exceptional. Because access is limited, it never feels crowded. The silhouette of the historic structures against the evening sky adds a dimension you won’t find at a beach or park.

Note: Check ferry schedules in advance. The last ferry back may depart before sunset depending on the season, so plan accordingly.

Sunset Bay Park, Grassy Key

Just north of Marathon on Grassy Key, Sunset Bay Park is a quiet natural area with Gulf-side views, native vegetation, short walking trails, and a pier. It’s less well-known than the other spots on this list, which is part of its appeal — you may have the sunset nearly to yourself. The park’s natural setting feels untouched, with flowering vines and various species of palms, and it’s an excellent spot for a peaceful evening stroll before or after sunset.

Sunset With Dinner: Waterfront Restaurants

If you’d rather watch the sunset with a cold drink and a plate of fresh seafood in front of you, Marathon has excellent options.

Hurricane Grille at Blackfin Resort — You don’t even need to leave the property. Hurricane Grille’s outdoor seating faces the Gulf side, and the laid-back atmosphere makes it easy to settle in for the evening. Grab a table, order dinner, and let the sunset come to you.

Sunset Grille & Raw Bar — Located at the foot of the Seven Mile Bridge at Mile Marker 47, Sunset Grille is built for this moment. The tiki-style restaurant has a large oceanfront deck, a pool, and a sandy beach area. The views of the bridge and the open Atlantic during golden hour are hard to beat.

Island Fish Company — With panoramic Gulf views and what’s reportedly the longest tiki bar in the Keys, Island Fish Company is a popular sunset dining spot. The patio faces west, so you get a direct view of the sun going down over the water.

Porky’s Bayside BBQ — A waterfront tiki restaurant on the Gulf side with live music nightly from 6 to 9 PM. The relaxed atmosphere, smoked BBQ, and sunset views make for a great combination. Pet-friendly too.

Keys Fisheries — More casual and counter-service style, but the waterfront picnic tables offer solid sunset views along with their famous lobster reuben. It’s a great option if you want good food and good views without a long sit-down dinner.

Sunset Cruises

Watching the sunset from the water takes the experience to another level. Out on the open Gulf, there are no buildings, trees, or anything else blocking the view — just a 360-degree horizon with the sky changing color all around you. Several operators in Marathon offer sunset cruises, from catamarans and sailboats to the popular Cruisin’ Tikis floating tiki bars. Most trips last about two hours and include drinks.

For something more active, Florida Keys Kayak and Paddleboard runs a sunset kayak tour that takes you through mangrove tunnels before opening up for the sunset. After dark, the kayaks are fitted with underwater LED lights so you can spot marine life on the paddle back. It’s one of the more unique sunset experiences available anywhere in the Keys.

From Your Own Boat

If you’re bringing your boat to the Keys or renting one during your stay, the best sunset views are from the water. Launch from Blackfin Resort’s boat ramp, motor out into the Gulf, and drop anchor wherever the mood strikes. Some of the best spots include the shallow sandbars west of Marathon, the waters around the Seven Mile Bridge, and anywhere along the Gulf side with an open western horizon. Bring snacks and drinks, and you’ve got your own private sunset cruise.

When to Watch: Sunset Times by Season

Sunset times in Marathon shift significantly through the year. In summer (June), the sun doesn’t set until around 8:15 PM, giving you a long, warm evening. In winter (December), sunset is closer to 5:45 PM, which means earlier dinners and quicker transitions to dark. Spring and fall split the difference with sunsets around 7:00–7:30 PM.

The best colors often appear 15–30 minutes after the sun dips below the horizon. Don’t pack up and leave the moment the sun disappears — stick around for the afterglow, which can be even more spectacular than the sunset itself. A few clouds on the horizon actually make for better sunsets, giving the light something to bounce off and creating more dramatic color.

Sunset Photography Tips

• Arrive early. The light 30 minutes before sunset is beautiful in its own right and gives you time to find the best angle.
• Stay late. The afterglow 15–20 minutes post-sunset often produces the most vivid pinks and purples.
• Include foreground interest. A dock, palm tree, boat, or the Seven Mile Bridge gives your photo depth and a sense of place.
• Use your phone’s HDR mode. It handles the contrast between a bright sky and darker foreground better than the standard camera mode.
• Turn around. The sky behind you often lights up with reflected color. Some of the best sunset photos face away from the sun.

Watch the Sunset From Blackfin Resort & Marina

Blackfin Resort & Marina sits on the Gulf side of Marathon, which means sunset views are built into your stay. Walk down to our private beach or waterfront area in the evening and watch the sky put on a show. Grab dinner at Hurricane Grille without leaving the property, or take your boat out from the marina for a sunset on the water. If you want to explore, Sunset Park and the Old Seven Mile Bridge are both just minutes away.

The sunsets are free. The memories are priceless. But someone had to say it.
