Sunset Bench via Lower Clamshell Trail

The trail is approximately 4.6 miles (7.4 km) out-and-back. While the komoot tour data suggests a shorter duration, given the steady incline and varied terrain, most hikers should plan for 2 to 3 hours to complete the round trip, allowing time to enjoy the views at Sunset Bench.

The trail primarily follows a fire road, making it wide and generally accessible. However, don't let that fool you; it features a steady ascent through chaparral-laden hillsides with some steeper sections that will challenge your calves. You may encounter dirt jeep roads, steep switchbacks, and in some areas, ruts or washed-out sections, especially after rain. There are also options for more experienced hikers to take singletrack paths.

While generally considered 'easy' by komoot, the trail's steady incline and some steeper sections make it moderately challenging for those new to hiking. Beginners should be prepared for a good workout, especially on the ascent. It's a great trail to build stamina, but be aware it's not entirely flat.

Parking is available on North Canyon Blvd in Monrovia. From there, you'll have a short walk up to the official trailhead for the Monrovia Hillside Wilderness Preserve.

Spring is an excellent time to visit, as wildflowers are abundant, adding vibrant colors to the chaparral landscape. For the most stunning views, plan your hike to reach Sunset Bench during the 'golden hour' as the sun sets, offering breathtaking panoramic vistas across the San Gabriel Valley.

As you hike, you'll pass by oaks, sycamores, and typical chaparral flora. Keep an eye out for scurrying lizards and red-tailed hawks. There's also a possibility of encountering deer, squirrels, coyotes, and even less common sightings like cougars or bears, so always be aware of your surroundings.

The primary destination and landmark is the 'Sunset Bench' itself, which offers expansive, panoramic views across the San Gabriel Valley. Along the ascent, you'll also enjoy constant views of rolling hills to the south and mountain peaks to the north, with Monrovia coming into view partway through the climb.

To avoid crowds and experience the trail at its most tranquil, consider visiting on a weekday morning. While the sunset views are iconic, a morning hike offers cooler temperatures and a different perspective of the valley waking up. Also, be aware that some parts of the trail can have ruts and washed-out sections, especially on switchbacks, so wear appropriate footwear.
