To get around Azusa, renting a car would be the best option as the natural locations to visit are quite a distance from each other. Plan to spend about $200 for a rental car for the week. Make sure to also budget for gas, approximately $50 for the whole trip.
If you have more time, consider visiting the Mount Baldy area for some beautiful scenic drives and hikes. If you have less time, shorten some of the activities and consider combining some locations.
