Reviews Summary

Visitors rave about the stunning 'mini Grand Canyon' views at The Sinks, calling it a beautiful and wild part of Orange County. However, the strict reservation system and limited access are a frequent point of frustration for those unable to secure a spot. The extensive hiking required is also a consideration for many. Reddit

"You must register online and make a reservation in order to get in. I followed a tour today and the group of 25 people hike together and we visit one side of the sink. I plan to visit the other side on a open pass access day. The park is beautiful and worth the 10.5 miles hike in my opinion. If you can walk that long at a moderate pace with confidence, you should come and see it. You should have some hiking experience or otherwise the entire group have to wait for you."
