Chugach State Park is Alaska’s most visited protected area and, at 495,000 acres, the third-largest state park in the United States. It spans the mountains directly behind Anchorage, providing over 280 miles of maintained trails and an untold number of off-trail routes into some of the most spectacular alpine terrain in North America — all within 30 minutes of downtown. This atlas covers the park systematically: major trailheads, parking and fees, trail difficulty ratings, seasonal conditions, wildlife calendars, and regulations. Whether you’re planning your first day hike or your tenth backcountry expedition, this guide will help you navigate the park like a local.
