San Gabriel Canyon Road & Mt Baldy loop from Lario Staging Area

The loop typically starts from the Lario Staging Area, which offers convenient parking. It's a popular and accessible point to begin this challenging ride.

The terrain is varied and demanding. You'll encounter smooth pavement on San Gabriel Canyon Road (SR 39) with sections reaching an 8% gradient. The climb up Mt. Baldy Road is particularly steep, with sections averaging over 9% and even 13% near the top. Glendora Ridge Road offers a more winding and scenic experience with a well-maintained paved surface. Be prepared for significant and sustained climbs.

You'll experience stunning natural beauty throughout the ride. Highlights include picturesque views of the Morris and San Gabriel Reservoirs along San Gabriel Canyon Road. Glendora Ridge Road offers jaw-dropping mountain panoramas, with massive views of canyons and wooded peaks. The summit of Mount Baldy provides majestic vistas of the Angeles National Forest.

No, this is unequivocally considered a difficult road cycling route, requiring very good fitness. The sustained steep gradients, especially on Mt. Baldy, make it unsuitable for beginners. It's often compared to 'wrestling a bear' due to its intensity.

The best time to cycle this loop is generally during the spring and fall months when temperatures are more moderate. Summer can be very hot in the lower canyons, while winter can bring snow and ice to higher elevations, especially on Mt. Baldy. Always check weather conditions before you go.

While there isn't a specific permit required for cycling this route, portions of the ride are within the Angeles National Forest. You may need an Adventure Pass for parking at certain trailheads within the forest, though Lario Staging Area typically does not require one. It's always a good idea to check the latest regulations from the Angeles National Forest Service before your trip.

This route is primarily a challenging road cycling loop. While dogs are generally allowed on leash in the Angeles National Forest, bringing a dog on this specific, demanding road cycling route is not practical or recommended due to the distance, elevation, traffic, and lack of amenities for pets.

Amenities are scarce along much of the route. It's crucial to carry sufficient water and nutrition. The Mt. Baldy Lodge is a known cycling-friendly stop where you can refuel. Otherwise, be prepared to be self-sufficient for long stretches.

Yes, this route incorporates sections of several other paths. You will ride along parts of the 66 (California) and the San Gabriel River Bike Path, particularly near the start. It also briefly touches on the San Gabriel River Trail - Lario Connector and Thompson Creek Trail.

Given the difficulty and length, you should bring plenty of water, energy gels/bars, compact gearing, and good brakes. Layers of clothing are recommended as temperatures can vary significantly between the canyon and higher elevations, especially during descents. A repair kit, spare tubes, and a fully charged phone are also essential.

The Mt. Baldy climb is considered one of the toughest and most prestigious in the U.S. cycling community. Its sustained steep gradients, particularly the final 8.2 kilometers averaging 8.1%, have earned it comparisons to famous European climbs like Alpe d'Huez. It's a bucket-list ride for many serious road cyclists seeking a significant challenge.

While the main route can have traffic, particularly on SR 39, some cyclists opt for the Glendora Mountain Road and Glendora Ridge Road approach for a more scenic and generally quieter ascent or descent. These roads offer a different perspective and can sometimes provide a less traffic-heavy experience compared to the direct Mt. Baldy Road.
