The sensory garden makes this trail unique in all the trails for people with visual impairments that I have walked. It is a beautifully designed space with a stripe of cobblestone underfoot as a tactile guide through the experiences offered there. The garden is edged in a combination of stone walls, trees, and logs cut to establish lines of short stumps and logs cut in longer lengths set cleverly together in an almost braided effect on the ground. Within the variable interactive boundary are a few attractions that are lovely to behold with eyes as well as hands, including 2 wooden rowboats commemorating the history of boat use on the river, a xylophone or marimba bench that can be played while you sit on it, and a large boulder with a grinding space evoking the lifestyle of the first people who lived in the vicinity.
On the west end of the oval - the side closest to Watertown square - nearby there are a few picnic tables accessible off the continuing trail. It would be nice to see a navigational extension for blind trail users to these tables. They are quite a statement, conveying the flow of the river in their design. A few of the benches along the Braille Trail share similar elements and provide lots of enjoyable resting spots.
