South Rim vs. North Rim: South Rim (Open Year-Round): Best time is March-May and September-November (comfortable 20℃). April sees crowds but beautiful wildflowers. North Rim (May-October): Cooler by 10℃, with stunning pine forests and snowy mountains. Delayed opening this year, so check the website before planning. Safety Tips: Sun Protection: High altitude means quick sunburns. Always wear sunglasses, SPF50, and a wide-brimmed hat. Hydration: Hiking for an hour can consume 2 bottles of water. Limited water refill stations inside the park. Cliff Safety: Avoid risky poses on cliffs. It’s illegal and dangerous due to loose soil. Respect Native Culture: Do not touch rock art or build cairns. #GrandCanyon #TravelTips#SpringTravel
