Garmin Instinct Solar: Best Affordable GPS Smartwatch

The Garmin Instinct Solar has had an amazing new upgrade to the original watch that was launched about one year ago. This hiking watch now has a solar-charged battery that delivers endless hours of operation. This is an amazing feature for weekend warriors, backpackers, or thru-hikers who are out on the trails for days at a time.

We rate the Garmin Instinct Solar the best “most affordable” GPS smartwatch for hiking you can buy right now. There is also a special edition Instinct Solar watch. If you are looking for a luxury watch on the opposite end of the price spectrum, check out the Garmin Marq Adventurer.

This watch is like the baby sibling of the Garmin Fenix 6 Pro Solar that we rate as the best overall GPS hiking watch with full-color maps.

Now that you have a high-level understanding of what this watch offers, let’s now review the details that makes this the best most affordable GPS watch.

Top features of the Garmin Instinct Solar

I love it when a company improves its products quickly. I really am amazed at what Garmin has managed to do with the Instinct Solar in just one year. There are so many awesome features that you just could not get on a watch at this price point a year ago.

Extra long battery life

The battery life for this watch is nothing short of incredible. If you are hiking or backpacking in a sunny climate, I would be shocked if this watch power died on you. Essentially, you have very near infinite battery power with this watch.

  • Smartwatch Mode: Up to 24 days, 54 days with solar
  • Battery Saver Watch Mode: Up to 56 days, unlimited with solar
  • Full GPS Mode: Up to 30 hours, 38 hours with solar
  • Max battery GPS Mode: Up to 70 hours, 145 hours with solar
  • Expedition GPS Activity: Up to 28 days, 68 days with solar

Amazing! Not only do we think this is a great GPS watch for hikers, but due to this long battery life we think it is also a great option for trail runners.

Very durable: U.S. military standard 810

This watch is tough and is built to the U.S. military standard 810. This means that it is shockproof and water-resistant to 100 meters. The Corning Gorilla Glass on this watch is scratch-resistant as well for those accidental moments.

Multi GNSS Support

Do you adventure around the world? With the Garmin Instinct Solar, you can access multiple global navigation satellite systems (GPS, GLONASS and Galileo). Super important if you like to travel.

Built-in Sports Apps

If you are a multi-sport fanatic than you will love the built-in apps for surfing, swimming, running, biking, hiking, rowing, strength training, and more.

Smartphone notifications

This is a superb feature for fast power hikers that are constantly on the move. Toss your smartphone in a zipper pocket or your daypack and get going! Now you can see important notifications on your watch as you cruise to your destination. Relay emails, texts and other data directly to your watch face.

Power manager

Certain settings and sensors drain battery life. Battery life is key in the backcountry. The power manager that is in the Garmin Instinct Solar watch allows you to extend battery life to the max by implementing different combinations of settings. For example, turn off certain sensors you are not using, or make the watch check-in on GPS location less often along the trail. Super simple.

Wrist-based heart monitor

Get heart rate data on the go with alerts from the wrist-based heart monitor. Get an instant idea of how hard your heart is working on your hikes. Adjust your activity accordingly.

Stress tracking and body energy monitor

Usually, hiking reduces stress and invigorates your overall energy levels. Know for certain with the power of the powers of the wrist-based heart monitor and get an idea when you might need to take it easy.

Pulse Ox2 sensor

Heading up to high altitude? This watch allows you to gauge how well you are acclimating to the altitude as you hike. The Pulse Ox2 sensor uses light beams fired at your wrist to gauge how well your body is absorbing oxygen. This is an incredible feature, especially for those that are coming from lower altitudes. As you get higher up you will feel the effects of altitude. This feature will help you decide when you need to take a break, drink some water, eat some food, and inhale more oxygen to avoid altitude sickness which can become a serious health concern quickly.

ABC sensors

ABC sensors help you navigate the trail and avoid sudden shifts in weather. What are ABC sensors? The Garmin Instinct Solar has a built in altimeter to keep track of elevation data. The watch also has a barometer to monitor weather and alert you of upcoming changes. Finally, keep track of your direction with the three-axis electronic compass. There you have it, ABC.

Tracback routing

Another mandatory feature of a GPS watch for hiking. As you go, the Garmin Instinct Solar watch drops breadcrumbs that allow you to navigate the same route back to your starting point. You can also use the watch to guide you with point-to-point navigation.

Pairs for satellite communication + maps

Another key feature for hikers that like to get deep into the backcountry for extended trips. The Instinct Solar pairs with Garmin InReach Mini, other Garmin satellite devices, and the Garmin Explore App. This is super important when you are not in an area of mobile phone service. Every hiker that hits the backcountry should have these tools available for use. By integrating these devices you will be safer, and will know exactly where you are located on a bigger screen.

This concludes our review of the Garmin Instinct Solar watch that we think is the best GPS hiking watch that is somewhat affordable.
