National Parks: Passport Guide

Review by eFreeware

The idea behind National Parks: Passport Guide is simple and specific: a digital version of the passport book that park visitors collect stamps in. Instead of ink and paper, you keep a record inside the app, marking each park as visited, wanted or favorite and attaching the date of your visit. That single concept is what separates it from general travel planners, and it is the reason to consider it.

It is built for people who treat the US National Parks as a list to work through. If you have a shelf of park maps at home or a running tally of which ones you have seen, the app is organized around exactly that habit. Campers get something extra, because the app also surfaces campgrounds and their details for whichever park you are looking at.

It is free to install and supported by ads, with in-app purchases also available. The developer, Code200, states plainly that the app does not represent a government entity, and credits the National Park Service for the images and information it presents.

Tracking visits, bucket lists and favorites

The core of the app is the three-way marking system. Any park can be tagged as visited, added to a bucket list, or marked as a favorite, and those tags can be removed again later. It is a small set of states, but it covers the three questions most park enthusiasts actually ask: where have I been, where do I want to go, and which ones do I care about most.

The visit date is the detail I appreciate most. Recording when you were at a park turns the list from a checklist into a personal record, and it is the sort of thing that becomes more interesting the longer you keep it going. Someone who started collecting park visits years ago would get more out of this than a first-timer, simply because there is more history to enter.

Finding a park is handled with search, plus filters by state and sorting by name. That matters once the list gets long, since scrolling through every park alphabetically is not how most people plan. Filtering to the states you are traveling through is the more natural way to narrow things down, and the app supports it.

The developer also invites users to share photos with other users, which adds a light social layer to what is otherwise a personal logbook. It is not the reason to install the app, but it fits the collecting mentality: the record is more satisfying when it has pictures attached.

Campsite details before you commit

For anyone planning to stay overnight in a park, the campsite information is the most useful part of the app. Selecting a park brings up its campgrounds and campsites, and each entry can include accessibility notes, amenities, directions and regulations. Those are the details that decide whether a site works for you, and having them in the same place as the park record saves jumping between sources.

The campsites for a selected park can also be viewed on a map. Seeing where the campgrounds sit relative to the rest of the park is a practical way to judge how much driving a stay would involve, and it pairs naturally with the app's ability to locate parks on a map as well.

I would treat this as a planning aid rather than a booking tool. What the app does is present the campsite information the National Park Service publishes, organized around the park you have selected, so you can compare options before you commit to an itinerary.

Park information, alerts and visitor centers

Each park entry carries the practical information you would otherwise look up separately: operating hours, fees, passes, location, weather and directions. None of it is exotic, but it is the material you need before a trip, and having it attached to the park you are already tracking keeps the planning in one place.

Alerts are the part worth checking before you set out. The app shows the latest alerts, including park closings and other important notices, along with news about the park. Conditions in the parks change, and a closing can upend a long-planned visit, so a section that flags these is more than filler.

There is also a visitor center locator, which the developer frames as a help to people collecting cancellation stamps. That is a nice piece of understanding about how park visitors actually behave: the stamp is often the point, and knowing where to find the visitor center is how you get it. Local maps and guides round out the browsing side of the app.

Setting up and keeping your record

The app is free to download and carries ads, with in-app purchases offered alongside. It is rated for Everyone, and the image and data credits belong to the National Park Service.

Signing up and logging in lets you save your data in the cloud. Backing up your log is the one setup step worth doing early if you intend to build a record over several years: a visit log is only worth keeping if it survives a lost or replaced device.

The app was first published in August 2019, and the most recent update, at the end of October 2025, fixed a map popup and added new parks to the list. For a reference app that depends on park data, that kind of housekeeping is what keeps it usable.

Where this fits among park apps

This is a companion for the National Parks specifically, not a general outdoors or road trip app. Its value comes from doing a few park-related jobs together: logging visits, keeping a wish list, checking campsite details, and reading up on hours, fees and alerts. Someone whose travel revolves around the parks will find the pieces fit together; someone looking for a broad trip planner is in different territory.

The install base is modest, over 10,000, and the average rating sits at 3.9 from 66 ratings. That is a small enough sample that I would not read too much into it either way, but it does suggest an app with a committed niche rather than a mass audience.

The ads and in-app purchases are worth knowing about before you install, particularly if you plan to spend long sessions browsing campsites. The developer's own invitation for users to suggest features also tells you something about the app's stage: it is being actively shaped, and the roadmap is partly in the hands of the people using it.

If your interest in the parks is mainly about the stamp book and the list of places you have stood, this app is built around that interest rather than around it as an afterthought.

A digital passport for park collectors

National Parks: Passport Guide earns a place on the phone of anyone working through the US National Parks as a long-term project. The combination of visit tracking with dates, a bucket list, campsite details and park alerts covers the practical side of park travel without pretending to be a full trip planner. The cloud saving through an account is the feature that makes the record worth building.

The trade-offs are straightforward. It is free but ad-supported, with in-app purchases available, and it is a focused tool rather than a broad one. The rating average is decent rather than glowing, based on a small number of ratings.

My recommendation is for park collectors, campers who want campsite specifics before choosing a spot, and anyone who wants fees, hours and alerts in the same place as their visit log. If the parks are a regular part of your year, the app is organized around exactly the things you would otherwise track by hand.
