Great variety of trails; meander easier trails near the visitor center, or drive in to the park and spend a day [or more] exploring; follow the Superior Hiking Trail west from the campground for overlooks, then head north and traverse around Mic Mac and Nipisquit lakes before returning. See below for details on hiking to the waterfalls and from the Lax Lake Road trailhead.
**note the trail from the visitor center area to the falls has a lot of steps, so not the best for those with knee issues; instead, consider parking at the Superior Hiking Trail trailhead on Hwy 1 and hiking in [still some steps]
