There are several kayak rental companies in Glen Arbor that provide kayak rentals and drop in services. The Crystal river meanders through a series of loops to Route M22 in Glen Arbor. There is one ford required when the river passes under county road 675 West Crystal View Rd.
Alternatively from this site you can drop in across the road and kayak a short stretch of the Crystal river into Little Fisher Lake. From there Little Fisher lake connects to Big Fisher lake which then connects to Big Glen Lake.
