Of the three segments we’ve divided the Florida Keys Overseas Heritage Trail into, the Lower Keys provide some of the best panoramas along the trail.
Sweeping views of shallow flats dotted with mangroves open to vistas along Florida Bay and behind the reefs of the Atlantic Ocean.
With longer continuous segments of bike path and paths out of sight of US 1, it has some good short scenic trips along it for casual riders.
Riding down one of the restored and resurfaced historic railroad bridgesIt also has less traffic crossing the over bike path than along the rest of the trail, since with the exception of Key West the Lower Keys are less densely populated.
While we describe the ride northbound – since you are following US 1 North – in reality most of the time you’re headed compass east through this segment.
Most of the trail parallels US 1 on the ocean sideResources

Open daylight hours to pedestrian and bicycle use. Hikers should use sunscreen and insect repellent. Leashed dogs welcome. Please pick up after your pet.
Class 1 ebikes (pedaling required) are permitted on state trails but other motorized transport is banned on bike path segments.
Because this is an island hopping route, sun and wind play a factor in your enjoyment of the ride. Check wind direction and speed before deciding which direction to ride, or to ride at all.
Flush toilets and running water are limited to several parks along the route as well as stops at convenience stores. Lock up your bike when leaving it unattended at restrooms and trailheads.
Read our information about poisonous plants in Florida before you ride. Along this trail are forests where both poisonwood and manchineel trees are present. Avoid touching them.
Florida’s Toxic Trees Southeast Florida is home to two poisonous trees, the poisonwood and the manchineel. Learn how to recognize them so you don't get too close, and find out how truly dangerous they are. Trail Details
Where you start depends on your logistics. The Southernmost Point buoy is compelling geographically, but it isn’t actually along the bike path.
To get there, it’s best to park at Astro Park, Higgs Beach, or Indigenous Park to do the road ride: Atlantic Blvd south to Reynolds St to South St. Round trip is 2 miles from White Street.
Don’t plan to get a selfie at the buoy, as there is always a line. Ride on by.White Street is where the trail terminus marker for the East Coast Greenway adjoins C.B. Harvey Rest Beach Park, within view of the pier and the AIDS memorial.
Parallel Atlantic Blvd north along the bike path, passing by a walk-in entrance to the Key West Nature Preserve, a tiny patch of nature next to the beach.
At the terminus marker for the East Coast GreenwayThe trail rounds the corner at the T intersection and faces the Atlantic Ocean. When you reach the beach you’re at the south end of Smathers Beach.
While the beach continues for more than a mile, the bike path stays below a wall so views are only at access points.
Shallows as seen from the bike pathNorth of the beach, the bike path is right at the seawall and it’s here you get the most expansive views of the Atlantic Ocean in Key West.
The lack of wave action is because most of the Florida Keys are edged by coral reefs on the Atlantic side, breaking the waves beyond your view.
Cow Key ChannelTurning away from the ocean, the path stays along the water’s edge up Cow Key Channel, where houseboats sometimes anchor in the shallows.
Passing a couple hotels, the Riviera Canal, and the Navy Health Clinic, you come to US 1, 4.6 miles north of the Southernmost Point.
The first US 1 crossingCross it at the light on the crosswalk and turn right to follow the bike path along the bay side of US 1.
Once over the bridge at Cow Key Channel, you’re on Stock Island. The trailhead at the Key West Tropical Forest & Botanical Garden is just a little west of the next traffic light at College Rd.
A nature nook at the Key West Tropical Forest & Botanical GardenThe only two campgrounds near Key West, Leo’s and Boyd’s, are on back streets on the opposite side of US 1 and can be reached by crossing at either of the next two traffic lights.
A convenience store sits at Key Haven Rd at 6 miles. These stores are very infrequent in the Florida Keys so if you need water, stop and buy some.
Underpass at Boca Chica ChannelAt 6.6 miles the trail reaches its first Florida State Parks sign as it passes a pulloff area along the southbound lanes of US 1.
It goes under the highway to reach a dedicated bike lane on the northbound side of the US 1 Boca Chica Channel Bridge.
Crossing Boca Chica ChannelOn the other side of the channel is Boca Chica Key, home to the Key West Naval Air Station. The bike path dips down a ramp to pass the main entrance at 9 miles and back up again to US 1.
At the top of that ramp the bike path comes to an abrupt end and forces you onto the US 1 bike lane briefly to get around a culvert.
A very brief break in the bike pathWhile this is a very minor break in the path, much longer breaks happen frequently farther north, where you must ride the bike lane in the direction of traffic travel.
Leaving Boca Chica Key, the trail uses the first of the first of the historic railroad bridges that make this such an interesting bike route, the Rockland Channel bridge.
Starting across the historic bridgeThe next convenience store adjoins the trail at Boca Chica Rd, just a quarter mile before the parking area at Shark Key wayside.
Just past the pulloff at 12.3 miles, the trail crosses the historic Shark Channel railroad bridge. The next several miles are especially scenic.
Taking a break before the bridgeAs the trail traverses the Saddlebunch Keys, using several historic bridges, you have broad views on either side.
Look down where possible, too. The clear aquamarine water is shallow and you can see sea life at the base of the mangroves.
Shallows along the trailBaby’s Coffee is a Keys icon and a popular stop before the nearly continuous bike path ends, forcing you into the bike lane of US 1 at Lower Sugarloaf Channel at 16.3 miles.
This is the first, but not the last, of the old railroad bridges that you can’t cross. Some will eventually be restored. Others have become fishing piers.
Riding the US 1 bike lane adjacent to the old bridgeCross over two bridges in the Sugarloaf Keys along US 1. The bike path doesn’t reappear until S. Point Drive, 1.4 miles north of where it ended.
It crosses to the bay side of US 1 at a somewhat pointless crossing: don’t take it unless you’re stopping at Sugarloaf Lodge, as you’ll only have to return to the northbound bike lane soon after.
There is no bike path along Park KeyThere is no bike path between Sugarloaf Lodge and Park Channel, where at 19.5 miles cyclists can get out of the bike lane to cross the historic Park Channel railroad bridge.
After the pulloff on the north side of the bridge, you’re right back onto the US 1 bike lane again.
Park Channel and some of the other bridges have a “bike only” lane painted down the middleAt 20.8 miles, the bike path begins again at Johnson Rd on Sugarloaf Key. Watch out for darting iguanas as you pass a short stretch of forest.
Mangrove Mama’s restaurant is on the other side of US 1. A large KOA adjoined the trail just before the historic Bow Channel railroad bridge, but their website indicates they are still closed.
Taking a break on the bridgeEnjoy nice views across Bow Channel on this crossing. Not far past the pulloff at the north side of the bridge on Cudjoe Key, the trail crosses US 1 to the bay side.
Our experience is that traffic doesn’t stop for crosswalks. But the trail remains on the bay side across all of Cudjoe Key, so cross over.
Crossover on Cudjoe KeyThe north side of Cudjoe Key has massive salt flats, which the trail skims along the edge of along the historic roadbed of old SR 4.
After a side road crossing, you’re in a dense mangrove forest for the rest of this island. At 21.1 miles, the trail crosses US 1 again, this time to lead to the historic Kemp Channel railroad bridge.
Riding old SR 4Passing through a paved parking area on the north side of this bridge, keep alert for another hop across US 1 to the bay side.
A boardwalk leads the trail to the edge of the flats, where you turn right to continue north via Old SR 4 on Summerland Key.
Taking a break on the connecting boardwalkA mile later, the bike path swings out towards US 1 and parallels it on the bay side before coming to another crosswalk to the ocean side.
After the crosswalk, it crosses East Shore Dr and continues up to the disappointing fence across the Niles Channel bridge, which has yet to be restored for trail use.
Fence across Niles Channel BridgeBefore you get to that fence, hop over to the bike lane along US 1 northbound again. Niles Channel is quite wide and you’ll see a big chunk of the railroad bridge is missing.
On the north side of Niles Channel make a quick jog off the highway to the right to get back on the bike path. Beware the soft sand.
Keep alert for iguanas on this ride, tooThe bike path parallels US 1 northbound all the way across Ramrod Key. Crossing W Indies Dr, you’ll find a convenience store and the Looe Key Dive Resort.
The bike path ends at the end of the island at 28.6 miles, so jump back in the US 1 bike lane to cross over to Little Torch Key, where the path resumes again.
View across the channel to Little Torch KeyThe bike path deposits you onto US 1 for a bridge crossing, and then is continuous to the end of this island, where you hit the next closed bridge.
Back in the bike lane, you can see the bad shape that the railroad bridge is in. Thirty miles into the ride, hop back onto the bike path north of the channel.
Following the bike path towards Big Pine KeyIt lasts until the next bridge crossing. Note the signs regarding Key deer habitat. This next island is Big Pine Key, one of the largest in the Florida Keys.
It’s here that you need to watch for vehicles crossing and stopping on the bike path, as the path passes many businesses.
Keep alert for vehicles on the pathAt Big Pine Key Blvd, a side path leads past the largest shopping center between Key West and Marathon into the National Key Deer Refuge.
If you’re not stopping for food, restaurants, or a side trip to look for Key deer, stay on the ocean side of US 1. Otherwise swap sides at this light to visit the stores or the refuge.
Key deer can be seen roaming through yards on this islandThe path on the bay side of US 1 ends in front of the Nature Center for the Florida Keys NWRs, a new visitor center on the island.
On the ocean side, the bike path continues past St. Peters Church across from the Nature Center and then pushes you out onto the US 1 bike lane.
Joining the bike lane for the second causewayAfter the causeway a narrow strip of path flanks US 1 on both sides through the heart of the refuge, which is fenced. Rejoin the bike lane for the next causeway.
As the road curves and the causeway ends, the narrow path starts again. This time there’s a crosswalk, at 34.1 miles.
Campground at Big Pine Key Fishing LodgeIf you are not stopping at the Big Pine Key Fishing Lodge, which is just ahead on the right and has drinks and snacks at the campground store, use the crosswalk.
You must get to the bay side of US 1 for the next bridge crossing, a lengthy and scenic span across Spanish Harbor.
Starting across Spanish Harbor ChannelIf you haven’t run into conflicts with fishermen up to this point, this is where they start becoming commonplace.
Most of the bridges in the Middle Keys swarm with casual anglers who set up chairs, tents, and coolers. Watch out for people casting, too.
Anglers occupying much of the width of the bridgeAt the north end of this span, the bike path splits: a side swoop into the Spanish Harbor parking area, or a crosswalk to the ocean side of US 1.
Crossing Scout Key, you ride past two long-established Scouting camps, Camp Sawyer for the Boy Scouts and Camp Wesumkee for the Girl Scouts.
Riding past the Camp Sawyer entranceAt the north end of the island, the bike path swoops towards what was the grandest and longest railroad bridge in the Keys, the one over Bahia Honda Channel.
Until the early 1970s, US 1 still crossed it. Looking at the crumbling infrastructure, it’s a little terrifying both how narrow and aged it is.
The Overseas Highway was added above the railroad bridge after rail service endedBahia Honda Channel was the deepest natural channel the Overseas Railroad had to cross, and the resultant bridge designed won international engineering awards.
From this pulloff at 36.3 miles, you can see down the length of the span. But to cross the channel you must join US 1 in the bike lane.
Riding the US 1 northbound bike lane across the channelIt’s more than a mile across this highway bridge over Bahia Honda Channel, practice for the Seven Mile bridge that lies ahead. Expect a great deal of wind.
Once you reach Bahia Honda Key, the bike path uses an underpass to get to the bay side of US 1.
If you are not stopping at the state park use this underpass to get to the bay side of US 1If you are finishing your ride at the state park itself, ignore the underpass and ride up to the entrance, which you reach at 38 miles.
It’s another half mile to the parking area, where there are restrooms and a gift shop with a snack bar. An entry fee applies to cyclists.
Trail’s end at the Bahia Honda State Park entranceDuring our research, we wrapped up our first day with a stay at Big Pine Key Fishing Lodge, as it’s tougher to snag a space at Bahia Honda State Park.
To avoid park entrance fees (or if the park is full to capacity), other alternatives for end points include Spanish Harbor at 35.1 miles and Bahia Honda Channel parking at 36.3 miles.

A limited amount of parking is available at pulloffs adjoining the historic bridges along this part of the trail. Do not assume you can park overnight at these locations.
For overnight or multi-day trips, make arrangements in advance to leave your car at a state park or a business you’ll be patronizing along the route, such as a hotel.
Key West Transit runs the Lower Keys Shuttle up and down US 1 with scheduled stops between Marathon and Key West.
They can get you and your bike back to your car, or close enough. Plan your end point based on their stops, which include Bahia Honda State Park. Check their website in advance.
