Great warm and breezy walk with a ton of wildlife. I used to walk it 4x a week when it was open. Hopefully the renovations will be done soon!

I’m sure it’s a nice walk-but be aware it is CLOSED for renovation as of May 2017.

This is a fantastic walk over a bride even on the hotest of days, there is a breeze. I recommend it to anyone. This bridge is under renovation for the next 2-3 years.

Very easy. Went about halfway and turned around. Saw a sea turtle! Bridge was desperately in need of repair as of oct 2015; sounds like they have closed it for upkeep since then

This is a section of the old US1 highway that starts on the west side of Marathon and continues out to Pigeon Key. 4 mile round trip. Parking is available at the start. It runs parallel to the Seven Mile Bridge on the new US1 Highway. Walk or bike out and enjoy the breeze and year round warmth of the Keys.

We went this past weekend. Gorgeous scenery. Walked to the island. Caught some fish and walked back. Totally awesome family day!! The trail is the old railroad from a hundred years or so ago transformed. In order for this trail to be maintained they are asking for public awareness and help (when you visit the trail, there is no fee). The website to help the trail is We definitely plan on becoming a regular!!!

We rode our bikes to Pigeon Key, a little over 4 miles out and back. The path is not the smoothest on road bikes as it has quite a few cracks and seams. There are signs that say there is an admission fee to visit Pigeon Key, but we explored the island for over an hour and saw no one collecting money.

Hiked the 7 Mile bridge to Pigeon Key the last 2 mornings. With the breeze it's a nice walk. More to see on the bridge than you might think. Enjoy it before they close it to pedestrians.
