Summer (June to August): This is the peak tourist season. The weather is generally warm and conducive to outdoor activities like hiking, camping, and wildlife viewing. The park is bustling with visitors during this time, so expect crowds and book accommodations well in advance.
Fall (September to October): Many visitors consider fall the best time to visit Custer State Park because of the beautiful fall foliage. The park's forests turn vibrant shades of yellow, orange, and red, creating stunning scenery, especially along the Needles Highway and Wildlife Loop Road.
Spring (April to May): Spring brings milder temperatures and blooming wildflowers, making it an excellent time for hiking and wildlife viewing. However, some trails and facilities may still be closed due to lingering snow or seasonal maintenance.
Winter (November to March): Winter transforms Custer State Park into a winter wonderland. While some roads and facilities close during this time, you can still enjoy activities like cross-country skiing, snowshoeing, and wildlife viewing. The park's annual Buffalo Roundup typically occurs in late September or early October, attracting visitors from around the world to witness the spectacle of wranglers herding the park's buffalo.
