Never underestimate the power of flowing water. There are safe areas from which to view but the rocks can be covered with moss and slippery. At times of the year, there is a lot of water moving through the creeks and over the falls.
There are lakes, creeks and waterfalls throughout the Bella Vista region of the Ozark, but Tanyard Creek is easily accessible and a favorite for walkers. The Tanyard Creek trails are rated easy to medium depending on the route. The routes and loops are well-signed. The trails offer both hard and soft surfaces for your hike and include both a suspension bridge and a slightly less adventurous bridge over the falls. Bikes are not allowed on this part of the Bella Vista trails system. There is a large parking lot and restroom located at the trailhead.
Johnson recommends a polarizing filer be used for shooting waterfalls in any kind of light to cut glare off, not only the surface of the water, but reflected light from damp surfaces on adjacent rocks or leaves. By adjusting the amount of filtration with a polarizing filter you can capture or remove rainbows you sometimes get at the base or top of the waterfall.
If you aren’t going for satin-like waterfall and prefer to freeze the falls in place capturing the individual water drops you will need a little more daylight and a faster shutter speed. The more ambient light that exists, the faster your shutter speed can be and the more visible the drops will be.
