I've been to all 63 major US national parks. Here are 10 things I'd never visit one without.

• I stay safe by packing bear spray, a first-aid kit, and plenty of sun protection.
• Offline maps help me navigate parks where cell service is unavailable.

Offline maps come in handy when there’s no cell service in the parks.

First-aid kits are good to have on hand.

I like to bring multiple layers of clothing with me.

Snacks are important for maintaining energy.

Although some parks have concessions with snacks for purchase, they’re not always available. And many times, the nearest store is far from the remote parks.

I love to bring nuts, granola bars, dried fruit, beef jerky, candy, and an apple on my hikes.
