Planning a trip to any US national park this summer, know before you go – check out National Park Service (NPS) website or NPS App.
For each park, find information about current road conditions, weather and alerts.
Road conditions – Find current road status (roads can be closed due to flooding, landslides, wildfires), seasonal opening and closing dates, road construction, which can cause traffic delays.
Weather – To help plan when to visit, check out weather for each month in the park, day and nighttime temperatures. Weather alerts are particularly important, weather can be too hot to hike safely, excessive rain is flooding rivers and trail crossings, roads are damaged.
Alerts – Alerts will cover a variety of topics, from fire, smoke and air quality, conditions of trails, closed campgrounds, day-use reservations required, traffic congestion, when parking lots are full.
For some alerts, you may want to postpone your trip to a particular park.
Wildlife Safety
Never approach animals or block traffic to stop and view wildlife.
Always stay at least 100 yards (91 m) away from bears and wolves, at least 25 yards (23 m) away from all other large animals, including bison and elk.
Do not feed the animals, especially birds, squirrels and chipmunks. Chips and snacks are bad for many animals – feed them people food and they can end up dead.
Fire safety
Each summer, wildfires can be caused by lightning strikes and human activities. Drought, high winds and dry grass conditions create extreme fire danger.
Campfires are only permitted within the fire rings in campgrounds. Campfires must be attended at all times and don’t leave until they are completely out.
To see any wildfire alerts, check out NPS for the park you’re visiting and national weather service.
If a wildfire is burning in your area, don’t go out on a hike – air quality alone will make it unhealthy. Fires are unpredictable, access roads can close, trails may be engulfed in flames.
