Spring (mid-March through May) and Fall (September through October). Daytime temperatures in the 60°F–80°F range are ideal for hiking, mountain biking, off-roading, and rafting. Summer exceeds 95°F and is intensely hot; winter can drop to 20°F at night. Spring and fall offer the best balance of comfortable weather, open trails, and (outside of Easter Jeep Safari weekend) manageable crowds
