Pedro Bay is accessible by air and water. There is a state-owned gravel airstrip. Barge service is available from Naknek via the Kvichak River. Goods are also sent by barge from Homer to Iliamna Bay on the Cook Inlet side and portaged over a 14-mile road to Pile Bay, a village 10 miles to the east of Pedro Bay. An unimproved trail, the Iliamna-Pile Bay Trail, runs along the northern shore of Iliamna Lake, connecting Pile Bay to Pedro Bay and the communities of Iliamna and Newhalen to the west. The existing road between Cook Inlet and Pile Bay is used for the transport of fishing vessels from winter retrofitting in Homer to summer fishing grounds in Bristol Bay and back. It is also often the only route by which heavy equipment can reach the Iliamna area. The road has not been adequately maintained. It is narrow in places and several bridges need to be replaced. Improvements to this transportation link were identified as a priority in the 2011 Lake and Peninsula Borough Coastal Management Plan.
