To get around Whittier, it's best to rent a car or use a ride-hailing service like Uber or Lyft. Parking is available at all the points of interest on this itinerary, but be aware of parking fees at Santa Fe Dam Recreation Area.
If you have more time, you can explore other attractions, such as The Pio Pico State Historic Park or Whittier Turnbull Canyon Hiking Trail. If you have less time, consider skipping Santa Fe Dam Recreation Area or having a quick snack instead of a full lunch at Marni's Rose Cafe.
