To get to the above places, hiring a car is the best option. If renting a car is not possible, you can use ride-sharing services like Uber or Lyft. The average cost of a ride from Arcadia to the various locations is $15-$20, and the average travel time is 30-45 minutes.
If you have more time, visit the Santa Anita Canyon, the San Gabriel Wilderness, and Eaton Canyon. Don't forget to carry ample sunscreen, hats, and water bottles as the California sun is scorching. Keep your camera handy and buy local produce from the Visitor Center to support local businesses.
