Lake Superior Pebble Beach Professional Review and Guide
"A hike for the whole family that follows a long and wide stretch of Lake Superior shoreline. The Pebble Beach Hike, also called the Lake Walk, follows the Superior Hiking Trail for what must be its easiest and gentlest section; the shoreline trail follows the points and crescent-shaped bays of the lake. The beach at Park Point in Duluth has ample sand; this beach has plenty of flat pebbles.
One of the most popular sports among the Pebble Beach hikers is the fine art of skipping stones. The flatter stones here are certainly capable of a dozen skips. For amateur mineralogists or those who just want to know what they are throwing, the assortment of rocks includes red felsite, gray basalt, granite, jasper, and the occasional agate that got washed in from Isle Royale or Canada. Special attractions: The wind and waves of Lake Superior, beach-combing, and skipping stones."
