April 7, 2024,Ed Towsley Canyon
Some areas of the trail have been eroded by the heavy rains recently. Some sections require crossing water streams.
Blue clear skies today in Santa Clarita with just the right amount of warmth. I could smell the tarpits as well as the armpits. A small bobcat jumped out of the bushes in front of me and jumped back in. I too was ready to jump.
Don Mullaly trail to Elder Loop trail at Towsley Canyon in Ed Davis Park at Santa Clarita. Warm day, no stream water, dry vegetation. You can still smell the tar nearby.

Frequently Asked Questions

Where can I park to access the Don Mullally Trail?

The Don Mullally Trail is primarily accessed through Ed Davis Park in the Santa Clarita Valley. You'll find parking available at the park's entrance, which serves as a convenient starting point for your jog.

Are there any permits or entrance fees for Santa Clarita Woodlands Park?

No, there are generally no permits or entrance fees required to access the trails within Santa Clarita Woodlands Park, including the Don Mullally Trail. It's open for public enjoyment.

What is the terrain like on this route?

The terrain is quite varied. It starts with a level paved road, transitions to wide dirt doubletrack with a gradual incline, and then narrows to singletrack with winding ascents and descents. You'll encounter steep sections, some described as 'thigh burners' going up and 'knee breakers' coming down, along with concrete steps near tar pits and a tight canyon chute called 'The Narrows'.

Is the Don Mullally Trail dog-friendly?

Yes, the trail is dog-friendly! However, please ensure your dog is kept on a leash at all times to protect wildlife and for the safety of other trail users.

What's the best time of year to jog this trail?

Warmer months are great for seeing wildflowers, but be aware that some sections lack shade, making it a hot climb. The rainy season offers the chance to wade in Towsley Creek. Consider visiting in spring or fall for more moderate temperatures, or early mornings in summer to avoid the heat.

What notable features or landmarks can I see along the way?

You'll encounter several natural tar pits, a unique passage through The Narrows with interesting rock formations and a creek crossing, and panoramic views of the Newhall Valley and Polena Mountains. There's also a beautiful grassy picnic area shaded by cottonwood trees and the Towsley Canyon Loop Trail highlight.

Does this route intersect with other trails?

Yes, while primarily following the Don Mullally Trail (92% of the route), this jogging path also includes sections of the Wiley Canyon Trail (16%), Towsley Trail (10%), Towsley Canyon Loop Trail (7%), and Taylor Loop (2%).

Is this trail suitable for beginner joggers?

The difficulty varies. A shorter, 2-mile loop within Ed Davis Park is considered 'Easy with a few moderate hills' and is suitable for beginners. However, the full Don Mullally Trail, especially the longer loops, is classified as 'Difficult' due to significant elevation changes and steep sections. Beginners should stick to the easier, flatter portions.

Are there amenities like restrooms or water available?

Yes, particularly near the Towsley Lodge area, you'll find amenities such as a picnic area, restrooms, and a water fountain. The Sonia Thompson Nature Center, with wildlife dioramas, is also located there.

What should I bring for a jog on this trail?

Given the varied terrain and potential for steep sections, sturdy trail running shoes are recommended. Bring plenty of water, especially on warmer days, as some areas lack shade. Sun protection like a hat and sunscreen is also advisable. Consider trekking poles for the steeper descents if you have knee concerns.

What's the best strategy for tackling the steep sections?

The trail features challenging 'thigh burner' ascents and 'knee breaker' descents. For the climbs, pacing yourself and taking short breaks can be helpful. On descents, focus on controlled steps to minimize impact. If you're doing a longer loop, consider starting early to avoid the midday sun on exposed climbs.
