We did this hike earlier today, it is a great hike, wilth an awesome waterfall at the end. The hike itself is easy with only slight elevation changes along the route. The surface is a mix of boardwalk (lots thru swampy areas) and dirt or crushed rock. The hike takes you thru many different vegetation areas and a detour thru the moose (free) enclosure easily demonstrates the impact that moose have on the local vegetation. The other detour to little pond is worthwhile, but is a little more challenging with more elevation changes... a great hike, the falls are truly spectacular.
