Tips for Visiting National Parks in August

Prepare for Crowds: August is a popular time to visit US National Parks, so it’s important to anticipate higher visitor numbers. To make the most of your experience, plan ahead and consider arriving early to beat the crowds. Starting your day early allows you to secure parking spots, avoid long lines, and relish the serenity of nature before it gets busy.

Research and Plan Ahead: Take the time to research the specific regulations, permits, and any reservation requirements for the park you intend to visit in August. Some popular National Parks may have limited availability for campsites, accommodations, or activities. By planning ahead and making reservations in advance, you can ensure a smoother and more enjoyable trip.

Consider the America the Beautiful Pass: If you plan to visit multiple National Parks throughout the year, consider purchasing the America the Beautiful Pass. This annual pass grants access to over 2,000 federal recreation sites, including National Parks, and can save you money in the long run. It’s a convenient option for exploring different parks during your August adventure.

Check Pet Policies: If you’re traveling with pets, be aware of the pet policies of the National Parks you plan to visit in August. Some parks have restrictions on where pets are allowed to ensure the safety of wildlife and protect the park’s natural environment. Review and abide by these policies, and plan accordingly by making arrangements for your furry companions.

Practice Leave No Trace Principles: Respect the environment by following Leave No Trace principles. Pack out your trash, stay on designated trails, and minimize your impact on natural resources. By practicing responsible and sustainable outdoor practices, you help preserve the parks’ pristine beauty for future generations to enjoy.

Know Before You Go

Plan ahead: Take the time to research and plan your itinerary based on your interests and the available time. Keep in mind that certain activities, like backcountry camping, may require reservations, so it’s essential to plan accordingly.

Views of Denali Not Guaranteed: Denali, formerly known as Mount McKinley, is the highest peak in North America. It stands at an impressive 20,310 feet (6,190 meters) above sea level. Weather conditions often obscure the mountain, but clear days provide spectacular views. The best chance to see Denali is early morning or evening. 

Be Prepared for Spotty Cell Signal: When it comes to communication, be prepared for spotty cell signal. The visitor center area has excellent cell coverage, but as you venture farther away, especially a few miles from the center, the cell service rapidly deteriorates and may become virtually non-existent.

Check road conditions on Denali Park Road: Normally, private vehicles are not allowed beyond mile 15, and currently, due to a recent landslide, the road is closed beyond the East Fork River at mile 43, including buses. Stay updated on the road conditions to avoid any surprises during your visit.

Wildlife safety: In Denali National Park, wildlife is abundant, including moose and all three species of bears. It’s crucial to familiarize yourself with wildlife safety guidelines and maintain a safe distance from animals. Carry bear spray and be prepared for potential encounters while hiking or exploring the park.

Visiting multiple National Parks? We highly recommend getting the America the Beautiful pass, which costs about $80 per year and gives you free access to over 2,000 federal recreation sites, including ALL National Parks.
