The Chigmits, where the Alaska and Aleutian Ranges meet, are an awesome, jagged array of mountains and glaciers which include two active volcanoes, Mt. Redoubt and Mt. Iliamna. Numerous lake and river systems in the park and preserve offer excellent fishing and wildlife viewing. Open year round. Weather conditions in the region change suddenly and proper equipment, rain and cool weather gear, extra food, and extra cooking fuel, are essential for any back country travel. Frost and snow can occur in September and October, and in mid-summer evening frost should be expected.
Strong winds can occur at any time.
Access to the Lake Clark region is by small aircraft. Float planes may land on the many lakes throughout the area. Wheeled planes land on open beaches, gravel bars, or private airstrips in or near the park. There is no highway access to the park and preserve. A one to two-hour flight from Anchorage, Kenai or Homer will provide access to most points within the park and preserve.
