## What is National Park Trail Guide?

National Park Trail Guide is your comprehensive guide to hiking and site seeing in our National Parks.

• Currently packing complete trail data and hike descriptions for many of your favorite National Parks, including life-list destinations like Yellowstone, Yosemite, Grand Canyon, Zion, Grand Teton, Mount Rainier, Point Reyes, Rocky Mountain, Zion, Acadia and many more!
• Search for hikes using the map or a park's “best of” list curated through star rankings from the community.
• Never get lost again! See your live position on a terrain or satellite map and vertical profile
• No cell signal needed. The data is available offline, and your phone uses its built-in GPS to show your location.
• Plan the perfect trip for you, using our hike difficulty ratings, elevation profiles, star ratings, and informed insights on seasons, camping and lodging, guided tours, food and drink, and more.
• Traveling with kids? We have an expert-selected list of Family Friendly Hikes. Want to target the park’s most beautiful features? View our list of Gems.
• Other cool features: Create a to-do list, track your hikes, or send your exact location to help in case of emergency.
• The app is completely free--it’s our gift to you as part of the National Park Service's Centennial Celebration.

### 2/5 — Basemaps not loading

*2026-04-05, version 4.6.14*

Basemaps are not loading and we’re just getting to the spring hiking season!  Unusable until this is fixed.

Ahh, just clicked on support link - takes you to a website for a totally different app.  Looks like they’re not actually seriously updating this app anymore.

### 1/5 — Used to be great now maps don’t even load

*2026-01-24, version 4.6.12*

Used to be great now maps don’t even load

### 1/5 — Crashes on opening latest OS Mac

*2025-06-18, version 4.6.8*

Even deleting and redownloading fails to get the working

### 1/5 — Now Worthless!

*2025-03-26, version 4.6.7*

I updated the app today & now it quickly closes as soon as I tap to attempt opening it!  What was previously a beautiful, informative app is now completely worthless - even after deleting & trying to re-install it.

### 3/5 — Good but wrong

*2025-03-06, version 4.6.6*

Nice layout. Good info. But missing Canyon and NP in Utah but had a NM instead.

### 5/5 — Well designed

*2025-02-26, version 4.6.6*

Love this app for finding the not as crowded gems in the parks. I love all the trail details and difficulty ratings so we know what we are getting into. Recommend 10/10!

### 1/5 — Nothing

*2024-12-25, version 4.6.4*

I just ran across this app. Downloaded to iPhone and iPad (older). There is nothing here. No parks no search result. NOTHING. And yes I logged in to a new account.

### 3/5 — App Says it will take a second to update – It’s been 20 minutes

*2024-09-05, version 4.5.10*

I was enjoy using the app to research Glacier National Park.  Today I open the app and get message that app needs to update the data & that it will take a second.  Twenty minutes later, the app still is not providing any National Park information and keeps repeating the message.

App should be updated such that data refresh takes place in background and the current data is still displayed.

Current version is inconsistent and makes using it for planning unreliable.

### 1/5 — Won’t let me create account

*2024-06-30, version 4.5.8*

It won’t let me create an account. Can’t get past “enter email” page. Can’t use the app without creating an account 🤷‍♀️

### 4/5 — Almost perfect

*2024-05-26, version 4.5.8*

This is a fantastic app for learning about and enjoying the National Parks….for the ones they have decided to include. I wish it was all inclusive, as we are trying to visit ALL NP’s, but several are not included in this app.
