Make sure to bring enough water for everyone, as well as some extra in case of an emergency. Pack snacks and food as choices are limited once inside the park. Bring a small first aid kit too for any unforeseen scrapes along the way.
There are areas in the park where you may not have reception.
Take advantage of the cooler morning and evening temperatures. Avoid hikes during peak sun times.
Spring is the best time of the year to go. It’s generally a good idea to avoid going during the summer.
If you are planning to visit several national parks within the year, the “America the Beautiful” annual pass may save you some money. If a member of the family is in the military or if you have a fourth grader, they are eligible for free yearly passes.
