The Orange Belt Railway, which ran from Jacksonville to St. Petersburg, was once the longest narrow gauge railroad in the nation. Now, part of the line is a premier Florida rail trail. The trail begins in Altamonte Springs where it skirts lakes, pastures and a country club, connects to the Cross Seminole Trail via the Interstate 4 Trail Overpass in Heathrow, and enters the Wekiva River Protection Area. The Wekiva River is abundant with wildlife and quiet observers may see rare and endangered species such as the wood stork and sandhill crane.
