The Glendora Mountain Road (GMR) trail is the perfect choice if you want an amazing downhill biking experience with minimal risks involved. It consists of a single-track downhill trail that branches out as you approach the bottom, offering an array of different experiences with respect to the chosen path. Another section of the trail begins from a different point from the main road, offering a steeper ride laced with exciting jumps as you go down the hills.

If you’re looking for an amazing long-ride in the mountains, consider riding your MTB on the GMR trail. You can start all the way from the bottom and work your way up the 8-mile climb. Bear in mind that the journey towards the trail is quite a long drive in itself, but the overall experience is worth it. You can also opt for a shuttle ride with Crazy Bear Shuttle service – just pay for as many runs as you need to make tr buy a day-long pass for your ease.

​The fast and smooth GMR downhill trail allows you to put your speed and cornering abilities under the test. However, it doesn't offer much in terms of thrill unless you take the west-side trail. The main trail is quite long and splits off into three trails towards the bottom. For an easier ride, you can take the path towards your right. However, this path does get a bit slow and rocky as you approach the bottom. On the other hand, taking a left will give you a shorter yet more challenging ride with unexpected turns, sharp rocks, and nice jumps. The downside of this path is that it has more hikers coming up so you'll have to look out for that. And if you decide to go straight, get ready to put your mountain biking skills to test as this steeper section of the ride is quite challenging, even for experienced riders.

The west-side of the Glendora Mountain Road trail also offers a challenging experience with it’s steep, rocky descends and man-made jumps. Keep in mind that the path integrates a few gap jumps as well so make sure you’re confident with your mountain biking skills. It’s recommended to initially run down the trail without taking the jumps to check the ones you can actually cross.

On the whole, GMR trails offer an exciting downhill ride. Unless you're interested in riding all the way up on your mountain bike, taking the shuttle to get to the top is a good idea. It allows you to relax on the way up and keeps your mind from getting exhausted so you can make the most of your downhill ride. If you want to take another shot on the GMR trail, you can take the shuttle again when you get to the bottom.

It goes without saying that you should wear appropriate protective gear when going outdoors for mountain biking. Just a helmet is fine for a mere stroll down the main section, but knee and elbow pads are a must of you're planning to go down faster or on the west-side trail.

Right after the fire station will be a dirt parking lot where you can park your car and take a shuttle to get to the top. But if you want to reach the top on your own, you’ll have to drive for another 8.5 miles ahead of the parking lot to reach the downhill trail.

To access the west-side trail, you would need to ride for an additional 4.3 miles after the parking lot.
