(BPT) - From the geysers of Yellowstone to the granite cliffs of Yosemite, America's national parks remain a premier destination for outdoor exploration. For many travelers, visiting national parks is a bucket list ambition. In fact, one in four Americans aspire to visit every national park in their lifetime, according to a recent online survey conducted in January 2025.*

With warmer weather on the horizon and outdoor enthusiasts gearing up for the season - especially around moments like National Park Week, happening April 19-27 - now is the ideal time to start planning a national park adventure.

Before hitting the trail, OFF!^® Mosquito and Tick Repellents has partnered with the National Park Foundation to share six tips to help make any national park experience worry-free and more memorable, so you can focus on the adventure.

1. Reserve entry passes and campsites early

Many parks have moved to a reservation-based system to manage crowds. Book timed entry passes, campsites and guided tours well in advance. Highly visited parks like Arches, Glacier and Rocky Mountain often sell out weeks ahead.

2. Plan for unexpected weather and layer up

Weather can be hard to plan around. Temps can drop fast - especially at higher altitudes - and unexpected showers can change hiking plans instantly. Come prepared with extra clothing - like a lightweight jacket, waterproof gear and long sleeves - in case the weather changes. If camping, consider extra layers for chilly nights.

3. Don't let mosquitoes and ticks ruin the experience

With Mother Nature comes the presence of biting insects, like mosquitoes and ticks. Check the OFF!Cast Mosquito Forecast to see mosquito activity in the area up to seven days in advance. Bring a long-lasting mosquito and tick repellent, like OFF!^® Deep Woods, to help prevent bites and ensure the outdoors are enjoyed uninterrupted.

4. Pack high-protein snacks and water

The summer heat can drain you, especially in Southwestern parks like the Grand Canyon. Pack a large water bottle (two liters or more) and hydrate frequently. For longer hikes, consider packing a filtration water bottle or straw. Save room in your backpack for high-protein snacks to keep you energized.

5. The early bird catches the worm

For the most peaceful experience, arrive before sunrise. You'll beat the crowds and get a front-row seat at a beautiful sunrise.

6. See them all

Why stop at one? Visiting every national park may feel like a dream, but with planning, it's achievable. Make a plan by searching for national parks based on a location, activity or topic and get one step closer to adventure.
