Powder Canyon Loop Trail is a 6.1 mile moderately trafficked loop trail located near La Habra, California that features beautiful wild flowers and is good for all skill levels. The trail offers a number of activity options and is best used from March until October. Dogs and horses are also able to use this trail.
The whole park is awesome. Everything from easy to as long as you could possibly want. One can actually leave the park, pick up the trail next to Hacienda Rd, go to the
Buddhist temple and cross over Hacienda. There one will be on a green belt that goes nearly to the 605 in Whittier. I did about 25 miles one day and made it to probably Workman Hill. Still lots of trails to go.
No water so bring your own. Spring and summer there is little shade and lots of hills.
