Travel in Iliamna is usually by small plane, and seasonally by boat, four-wheeler, or snowmobile. Individuals also use personal vehicles, ATVs, and skiffs. Barges deliver bulk goods to the area via the Kvichak River. An improvised barge landing area is currently available at Iliamna. A breakwater, boat harbor, and dock are also available, although the dock is in poor condition. A state-owned airport with two gravel airstrips is located several miles west of Iliamna. Iliamna Air Taxi, Inc. provides scheduled mail, freight, and passenger air service to several Iliamna Lake communities. A private airstrip is located at the Iliamna Roadhouse, and Summit Lake provides private float plane access. A paved road connects Iliamna to the Iliamna airport, as well as the community of Newhalen located several miles to the south. During the winter, a road is passable between Iliamna and Nondalton, 15 miles to the north, although the road is only paved half way. Construction of a bridge is proposed at the western end of Six Mile Lake, which would provide year-round access to Nondalton. In addition, an unimproved trail, the Williamsport-Pile Bay Trail, runs along the northern shore of Iliamna Lake, connecting Iliamna and Newhalen with the communities of Pedro Bay and Pile Bay Village to the east. Pile Bay Village is also connected to Cook Inlet by road. This corridor is used to transport fishing boats and supplies between Cook Inlet and Bristol Bay, but is considered difficult to use.
