This trail is nearest to my home. It is a MUP that is lightly used for local folks, including me, who either walk, run or cycle. Savanah State Park is immediately to the east of this path, which has allowed me to see some wildlife a few times. The highlights have been one hog on the other side of the fence and two alligators on the actual Green River Parkway (GRP) path itself. One was a baby gator sunning himself as I cycled by and the other was about a 5-6 foot gator walking south as I was cycling north. It was pre-dawn, and my spotlight was not bright enough for me to see him far out. By the time I saw him, I was too close to try to turn back. So I rode right by him... he couldn't care less about me and kept going.
I say it's good for locals and gave the path a 3 of 5 stars for a few reasons:
1. There's little to no shade.
2. The Savanah State Park is next to the path, but the road is on the other side of the path. So it feels more like a sidewalk than a nature walk. I consider that a neutral aspect of the path, rather than a negative aspect.
2. The southern 1/3 of the path is relatively smooth, which is on the Martin County side of the path. But the northern St. Lucie County 2/3 of the path is quite bumpy. There are constant dips and imperfections in the surface of the path. I'd say this section is better for foot traffic or casual cycling, rather than serious road cycling. A bike with some shock absorption would be preferred. It's very frustrating for those of us who are avid road cyclists because it would be a perfect location to train intervals with a smoother surface. The uneven surface makes it difficult to feel like you can settle in for the ride.
3. Another neutral feacher of this path is that it starts nowhere and leads to nowhere. It doesn't connect any point of interest to any other point of interest. Yes, the Savanah SP is next to it and just north of it, but there is no access to the northern section unless you have a car. There is no sidewalk or bike lane on that road to the north of the GRP.
4. There are three nice "rest areas" with benches and bike racks, but there is no access to water or facilities. You must bring your own.
FYI: There is about a one mile southern extension of this path that is a concrete sidewalk from Jensen Beach Blvd. to Baker Road. This sidewalk is smoother than the asphalt GRP on St. Lucie County side. South of Baker Road, there is a bike lane on the street that goes about another half mile to Wright Blvd.
So the GRP is adequate if you are nearby, but I would not travel out of my way to visit this path. That being said, I'm glad we have it, especially when I want a short ride during rush hour traffic.
