Maps are available at the visitors center. See Juneau Trails for more details. Rubber-soled boots and rain gear are recommended for hiking. Plan to spend the entire day at the preserve. If you are an experienced paddler, you can rent a kayak and explore the inlets along Gastineau Channel on your own.
Most outfitters also offer day trips.
The Davis Log Cabin Visitors Center has a list of charter boat operators in Juneau who will take you fishing or out to view wildlife. If you like beer, ask for an Alaskan Amber or a Pale Ale. If you didn t sign up for the cruise-sponsored salmon dinner, you may not be out of luck. Both may be booked, depending on how many ships are in port. But there is sometimes room for a few more.
