You can walk downtown Petersburg, but you'll need wheels or a boat to get to most outdoor activities. The Tides Inn Motel and Scandia House both rent cars, but not many are available in town, so book well in advance for summer.
A boat opens more of the area than any other mode of transportation, allowing exploration of Wrangell Narrows, the trails on the far side, and the opportunity for inexpensive self-guided fishing. Jensen's Boat Rentals, in North Harbor (tel. 877/442-4010 or 907/772-4435), offers 18-foot skiffs and a 21-foot runabout with a top, with quality outboards and trolling motors, for $135 and $300 a day respectively, including a crab pot. The firm also rents fishing and shrimping gear.
