Monarch Migration (see more detail at www.99places.com) Head down to Pacific Grove to see the largest collection of Monarch butterflies in the United States. February is a great time to view the Monarchs as they winter in Pacific Grove. After a restful winter they start to wake up in January and February to look for a mate. Plan your trip on a warm day in February, as the Monarchs aren’t active unless the temperature is over 56 degrees. See the full description of this trip at www.tripicks.com.
