This trail starts in Gorges State Park (but eventually leaves the park property). Drive past the Visitors Center and down the hill to the large, paved parking lot. Downhill from the trailhead the trail splits - left is the Raymond Fisher Trail and right is the Rainbow Falls Trail. Go right. On the trail there are two creek crossings. The first is a shallow and easy two stepper but the second is a deeper six stepper. I made it across without poles. Rainbow Falls has two nice viewing areas (one farther away to take in the full view and one up close to feel the mist). Turtleback Falls is where all of the swimmers go to slide down the falls. There is no formal viewing area there but the large boulders are easy to climb and navigate and afford great views. The waterfalls are particularly picturesque.
