For fun, exhilaration, and exercise, hit the trail! But this just isn't any ordinary trek, this is the popular Santa Ana River Trail. This is an extensive, winding trail that runs along the Santa Ana River and offers walkers, hikers, joggers and bikers an excellent way to get out of the city and get closer to nature while getting some great exercise. The path stretches out over 70 miles, so there is plenty of room for you and your fellow trail-dwellers.
