Any mountain biker that appreciates the sport surely loves a good downhill cruise in the mountains but for those living here in South Florida, the trail riding options are varied. The are ways however, to minimize bike travel on busy streets and in high traffic areas. In Palm Beach County there exists a large amount of unimproved roads and pathways which were set up to accommodate the many canals and high-tension power lines. These open areas are maintained and well suited for skirting the busy intersections and road hazards on a bike. Many dead end roads, in fact, continue on along a path or canal and often hook up with a secondary road. It is a good idea to check first with the South Florida Water Management District in regards to public access.

There are certainly plenty of variations in the terrain that allow for catching air, bank turns, and bunny hops. Needless to say it makes an ordinary ride through a section of the city far more interesting. It is quite possible to cut across busy commercial areas to access a city park with biking trails. Rather than cross busy intersections, follow the power lines or a canal. In greater West Palm Beach many canal trails are often wide and susceptible to flooding with large deposits of sand. On other trails, such as those found within managed areas and farther west from the coast, the ground is hard packed, grassy, and shaded by pines. The experience of exploring the area off road is worth it and a welcome breath of fresh air from the exhaust fumes that often permeate the city streets. There still exists plenty of greenways to be found in Palm Beach County where natural areas are interlaced with neighborhood streets and are easy to access.
