Before you visit, check out these tips to enhance your trip! WeatherCheck the weather forecast before you head out! Winter and spring are wonderful times to visit giant sequoias, but it can be below freezing and very cool in the sequoia groves especially in the morning or evening. Weather can include snow and cold rain. Plan ahead by packing multiple layers of clothing so that you can adjust to warmer or colder conditions.Driving Mountain RoadsSnow is a possibility in the sequoia groves and rain or snow can occur in the foothills. Tire chains or cables are often required on park roads from fall through spring. Prepare for your visit by learning about tire chains and winter driving. From fall through spring, we recommend that you carry chains or cables in your car, regardless of conditions. Check out our current road conditions before arriving.Be prepared to drive winding roads with poor visibility and reduced traction. Our roads are steep and curvy, making them very dangerous and slippery to drive on in bad weather. Drive slowly and follow speed limits. Use turnouts when needed. Learn about driving mountain roads. Black IceBlack ice is patchy, transparent ice that cannot be easily seen. It forms on roadways during snowy or rainy conditions and during the spring when temperatures fall below freezing overnight. Roadways become very slippery when black ice forms, leading to hazardous driving conditions and an increased risk of car accidents. Please drive carefully and keep an eye out for black ice!Seasonal Closures and Road ClosuresDuring winter and spring there are multiple seasonal closures of roads, areas, campgrounds, visitor centers. Please double check operating hours before arriving! The following areas are closed at this time:
