Step-by-Step Guide

1. Planning Your Road Trip

Before hitting the road, it’s important to plan your trip carefully. Start by determining the best time to visit the Altadena Crest Trail. Spring and fall offer the most pleasant weather, avoiding the extreme heat of summer and the occasional winter rains. Check the weather forecast to ensure clear skies and safe trail conditions.

Next, choose your starting point. The most common trailheads for the Altadena Crest Trail are accessible from Loma Alta Park or the end of Altadena Drive. Map out your route from your location to the trailhead using a GPS or a reliable map application.

2. Preparing Your Vehicle

Since the journey involves mountain roads and potentially narrow or winding routes, ensure your vehicle is in good condition. Check tire pressure, oil levels, and fuel. It’s advisable to have a full tank before you start because nearby fuel stations might be limited.

Parking near the trailheads can be limited, especially on weekends. Arrive early to secure a spot or consider carpooling with friends to reduce the number of vehicles.

3. Packing Essentials for the Road Trip and Hike

Pack light but smart. Essentials include:

  • Water: Carry at least 2 liters per person to stay hydrated.

  • Sun Protection: Sunscreen, hats, and sunglasses.
  • Comfortable Clothing: Layered outfits suitable for changing temperatures.
  • Hiking Shoes: Sturdy, comfortable shoes with good grip.
  • Navigation Tools: Maps, GPS device, or smartphone with trail apps.
  • First Aid Kit: Basic supplies for minor injuries.
  • Camera or Smartphone: To capture the stunning views.

4. Driving to Altadena Crest Trail

Begin your drive to the trailhead by following your pre-planned route. The drive typically involves taking major highways like the I-210 or CA-2, depending on your starting location. Once you approach Altadena, follow signs for Loma Alta Park or the designated trailhead parking areas.

Drive cautiously on mountain roads. Watch for wildlife and be prepared for sudden changes in elevation. Use pullouts to allow faster vehicles to pass safely.

5. Hiking the Altadena Crest Trail

Upon arrival, check trail conditions and any posted notices. The Altadena Crest Trail spans approximately 4.5 miles one way, with moderate elevation gain. The trail offers panoramic views, shaded sections, and several spots ideal for resting and photography.

Follow marked trails and stay on designated paths to protect the environment and for your safety. Take your time to enjoy nature, and remember to leave no trace by packing out all trash.

6. Returning from the Trail

After completing the hike, return to your vehicle carefully. Stretch your legs and rehydrate before starting your drive back. If time allows, explore nearby attractions in Altadena or Pasadena to enrich your road trip experience.
