Book your visit to Irvine here.  

Irvine's trails are open from 10am - 4pm. There is no entry permitted after 3:00pm. General admission is free for members and $5/person for non-members. You must be logged in in order to receive free admission. 

Irvine's trails and associated online registration are closed every Monday, on any major holiday, and for certain weather conditions such as heat advisories, inclement weather, or air quality advisories. Online registration will not be available during these times, and trails will be closed to the public.  In the case you have pre-registered but were not able to visit before an advisory is released and we are required to close our trails, you will be emailed. We are happy to apply your registration to a different day. Thank you!

*If your membership is not linked to your online profile (your discounts or complimentary admission is not being reflected), or for general membership questions, please contact Elizabeth Cook at CookE@ExploreNature.org. Thank you!
