Directions to the Cabin
The Cabin is Located in Monrovia Canyon Park located at:

1200 North Canyon Blvd.
Monrovia, CA 91016
Off the 210 Freeway, exit Myrtle Avenue, drive through Old Town Monrovia to Foothill Blvd, turn right, go to Canyon Blvd, turn left, drive through residential area for about 1 mile staying to the right, turn right into Canyon Park at the 3-foot-tall sign. Once in the park, the cabin will be on the left hand side. Google Maps will direct you when coming from the 605 and heading West on the 210 to exit at Mountain Ave. Either way will get you there. 
UPDATE: Once you have entered the park, you will come to a parking pay station/kiosk. Parking is $5.00. We had planned on mailing out parking passes to everyone who had completed their RSVP and accepted. Instead, we have been informed that we can have the parking passes available for everyone right at the entrance kiosk. This is much easier...no parking passes to lose or left at home. So as you enter the park, just inform the ranger that you are attending the wedding at the cabin and they will give you your pass to display.
