  • Awesome app Nov 16, 2020

    By mpc64
    There’s so much info here it’s great. Just about every NP is covered and even some National Monuments and such. But what really impressed me was today when I was at Pinnacles NP I wanted to make sure I was going the right way on a trail in a place where I had no cell service s nothing else would even work. I opened the Trail Map and not only did it show all the trails, but it pinpointed where I was on the trail exactly. Thinking it may have been a lark I continued on and then tried it again. It took a second or two to update and then had moved my location along the trail. I moved off the trail a bit and even then it updated my location in relation to the trail and the parking lot I was headed to. I don’t know whether that works in all parks or not, but it was pretty amazing and may actually save people who’ve lost track of a trail, if they can see exactly where they are in relation to the trail, even in areas where there’s no cell service. Not sure how that works, but I was impressed.

    Used the app travelling across country. Good detail on maps and trails... Enjoyed using it to explore parks we would consider visiting in the future.
  • As a parkie, this is THE BEST app Nov 23, 2020

    By Grand Teton Man
    I spent last summer as an employee in GTNP and can say that this is the singles best app for hiking in the national parks. The map feature is amazing and intuitive, the trail profiles are super helpful, and the trails that have guides are very well written and helpful. Being able to see my location on the map even without service saved me a few times while hiking through the Utah desert. There are a few glitches every now and then, especially when switching between screens or trying to search for a trail, but overall works very well. If only this app worked outside the national parks.

    Great info for novice hikers and those of us who just love little hidden treasures near better known trails.
  • So much better than I thought! Jul 29, 2020

    By LilyAAG
    Really like this app! So useful with being able to find hikes offline and seeing where you’re at. The location is pretty darn accurate. I also really like how it tells you the elevation and mileage at various points of the hikes. Also so nice that you can add hikes to your “to do” list and then mark them as complete when you’ve done it! Some things that would be great to improve/add. One is there may be some glitch with adding “Gems” to your Completed list, it won’t let you for some reason. And it’d be great if the map can overlay the hikes you’ve already done so it’s easy to see where you’ve been, plus just would be super cool to look at

    Beautifully built app with lots of potential. Too bad that it doesnt offer directions to get to these places
  • Mar 24, 2020

    By Linda Hansen
    The app itself is nice, easy to navigate and easy on the eyes. The 1-star rating is due to the fact that there is no way of navigating (getting directions) to these trails. If you live near one, you can find it easily. If new to the locale/state, forget it.

  • Useless Oct 24, 2020

    By Triippp
    There is no list of parks anywhere to be found! I did find a way to get to the map, but the map does not show anything other than the name of the parks. You can see the geography And the town’s but there’s no indication of trails or park features anywhere . Pretty much useless! Well, after 4 months I get a response to my review. And it looks like some people have been waiting since January and February. At this point it looks like they rebuilt the entire app. Their solution was to delete and reinstall. Their updates did absolutely no good. I can’t say that I am encouraged by their lack of communication. I will not be giving them any more stars.

  • Used to be a good app. May 23, 2020

    By Karen LH
    I don’t know what happened with the last update. The app no longer works on my iPad. The nice UI that allowed you to easily get to the National Park that you want to see is gone. Instead, you get a screen that says “Guides in progress” and trying sort by most popular or alphabetically does nothing. If you attempt a search, you end up back on the search page with no parks found. Did Adventure Products take over this app and try to make it like their other products? If so, it was a bad idea—I can’t even get a park to come up, so I can’t review the trail information.

  • Crashing! Dec 3, 2018

    By Angrymonkeymermaid
    After the latest update it keeps crashing when trying to open it. And yes I have done everything: unloading and redownloading, shut down phone, exit and restart app. But to no avail. I use this app everytime we go to Acadia, although makes me wish we had more national parks in the Northeast, but I’m planning a road trip to Yellowstone this upcoming year and need this app to work. App is great for a good starting point when planning a trip and other info. If the app stops crashing then I’ll bring the app back again to 5.

  • Best hiking app! Oct 6, 2019

    By Grand canyon R2R
    I cannot say enough about how great this app is. I just hiked Grand Canyon rim to rim and used this all along the way. Clearly there is no service in the canyon but the app still worked and showed us all along the way exactly where we were. We were able also to navigate to side hikes and know we were on course. We threw out paper maps and just used my phone for this app. After the Grand Canyon we went to Bryce NP and were sore so not wanting to do big hikes so we just focused on seeing the gems rei suggestions and they were all amazing. Thank you rei for a great app!

    Pretty nice app. Some road names don't show up even when you zoom in, which kind of sucks. Also, the most annoying feature I have found about this app is that when you back out of a particular trail description page the app always takes you back to the beginning of the trail list. I just don't understand.

  • Fantastic app, just needs a little more work Aug 5, 2020

    By MaeFun
    I’ve had this app for about a year now, and it’s worked absolutely perfectly! There is one thing though that is annoying, and that’s the inclusion of NPS units that aren’t National Parks. It would be great if there was a way to filter those out, maybe through a main menu screen giving the option to chose from “National Parks” and “All National Park Service Units”. Another thing is that the map for the territory of Virgin Islands National Park does not include the “newly” acquired Hassel island off of St. Thomas. But other than that, this app is phenomenal and deserves a ton more attention!

  • Great App! Oct 13, 2020

    By Shea al'Thor
    This app is fantastic for visiting parks. I’ve used it on several trips now and it makes planning and exploring super easy! Only issue I have with it is that there isn’t a way to delete downloaded content after your trip. So after a while the app had several gigabytes of data downloaded to my phone (hike paths, park info, photos, trail ratings etc.) Being able to download parks for offline use is super handy for when traveling outside of cellular coverage, but we need a way to delete the data when we no longer need it.

  • They destroyed the app Oct 24, 2020

    By weswilson4
    Unclear why the development of the app necessitated having to delete it and download it again, but it’s working again. They have a lot of national parks but not all. It would be nice to see the parks on a national map so you could see which ones are near you — even those that don’t have guides. Also, having just used it, the Grand Canyon would be slightly more helpful if it was split between north rim and south rim.

    By Patrick Horton
    This is good, but I wished that it had many more parks or the option to add more. I downloaded it to see what it had on the State Park that's in the same county as me, but it doesn't have anything on it. I would use it if it had all state parks.

    By Mike McMahon
    The idea is good. However, you can find info on the best known National Parks anywhere. As this is app has REI associated with it, I expected more"off the beaten path content". l want to be informed of places I wouldn't otherwise know about in an app like this. The content it does have is great quality. And it is free. But you need to try harder to improve and expand your content.

    I was looking for a detailed, interactive, physical map. This has that, but I wish there were better labels for the geography (e.g. Fruita Cliffs, Navajo Sandstone domes). It's just Google.
  • App is not working on iPhone 7 Plus May 24, 2020

    By Mar-feja
    Not sure if it was discontinued or it is just not working on my phone. When I open the app it offers me to go over to 3 other apps one of them is the hiking project (which is not user friendly, I still can’t figure out how it works and what’s the purpose). But I really liked the National Parks app, not sure what happened though

  • All park cameras Dec 5, 2020

    By Ralph Dady
    Tired of trying to view live camera shots in all the parks and finding at least half of them don’t work. Grand Canyon and Yellowstone not working. Denali only one working, North Cascades hasn’t been working for at least 2 years. And the one I check most often, because it’s closets to me quit working about 6 months ago. I wish there could be something done about it. Since it’s government, I doubt if anything will happen be. Considering deleting app. Ralph Dady

  • Michigan is out of luck Aug 27, 2019

    By RedBearMich
    I have recently started to hike and am a photographer so I love hikes that provide photography opportunities. Michigan is home to Pictured Rocks National Lakeshore (not in the app), Sleeping Bear Dunes National Lakeshore, voted ‘Most Beautiful Place in America’ by Good Morning America (not in the app), and North Country National Scenic Trail (not in the app), Huron-Manistee National Forest (not in the app), and Hiawatha National Forest (not in app.) Why have you forgotten Michigan. As much as I would love to see all the other park and National Forests, I want to start at home. I am sooo disappointed.

  • Outdated information, disjointed organization Mar 26, 2019

    By Why play at all?
    Too bad they don’t update the information in this app. March 2019 : Just saw that a location is expected to be re-opened in 2017– so how can other info be trusted? When telling you about the Mist Trail, they don’t mention you have to hike to Vernal Falls to get on the trail. They tell you about hiking to Artist’s Point, but the trail is not listed in their trails or hikes.

  • Family Unfriendly section Jul 14, 2018

    By jelwell
    For Zion National Park they offer a Family Friendly section. The number one suggestion is Angels Landing hike. A hike with multiple deaths including a 13 year old girl in 2018. The National Park Service lists this hike as one of the most strenuous and not for young children. I hike and camp with my kids every month and do long hikes with them. Whoever curates the REI family friendly section should be held liable when families use the app as a reference. The app says, “kids that reach the top will never forget the journey or the view”. That 13 year old girl who died doesn’t remember the view.

  • App needs work Nov 12, 2020

    By 44hg789 w2a88
    The app isn’t functioning well. It’s difficult to make a to do list and even more difficult to check in. The button to check in doesn’t work. It’s impossible to check in retroactively. Would love to be able to make a running list of all the places I’ve been but cannot do so in this app.
