1. Late fall is best
Fall colors don't usually appear before November in our canyons.
2. Come during "bad" weather.
After (or during) a rain is the best time. The moisture saturates the leaves and also the color. Trabuco Creek Road is dirt of course, so you will need high clearance vehicle (and possibly 4x4) if it's raining. A sunny day following a storm can also be a great time.
3. Adjust your expectations.
This is not Vermont. On the other hand, if you come in December, it'll probably be 65 degrees outside and not 22 degrees.
4. The canyons are great,but don't forget about the chaparral.
The buckwheat and deerweed turn a golden bronze in the fall. The temperature is far more comfortable than the summer and the bugs and flies are gone. This is a great time to hike the ridgelines.
5. Don't come too late.
A strong Santa Ana wind or early winter storm can vacuum the fall colors from the canyons. The prime season is typically between early-mid November and the end of December.
6. Get out of the car.
Good locations such as Trabuco Creek trail require a short hike (3 mile out & back).
