99% of the mountain biking population calls this exact route "Whiting Ranch Loop", or just "Whiting" for short.

This is a great loop through Whiting Ranch that has many branches to create your own trail suitable to your enjoyment and fitness level.

Need to Know

There's a mountain Lion warning for this area. Be alert. It gets pretty busy on weekends so come early. Very popular with local hikers so be prepared to share the trail. You can only traverse Borrego Trail in one direction on a bike. If you want to return (ride the Borrego Trail backward to the starting point) you are supposed to walk your bike.


Park in the shopping center across Portola Parkway. Cross Portola and start at Borrego Trail. Borrego Trail is a one-way, very slight gradual positive grade for approx. 2 miles. At the end of Borrego take the fork to the right up Mustard Road.

Mustard Road is a fire road that gets steep as you get further up it. The road is about .6 miles with around 350' of climbing. At the top you'll reach 4 Corners.

Begin a singletrack section by going down Cactus Hill Trail. At the first fork in the road, continue right down Sleepy Hollow Trail. Take the next fork right at Serrano Cow Trail. Meet up with Live Oak Trail or Serrano Creek Trail and continue until you're back to Portola Pkwy. The last .75 miles, head west on Portola to get back to where you parked.

Great too see this tool being made available. A few comments - can you PLEASE list this and related Orange County rides as Orange County and NOT Los Angeles! We are NOT in Los Angeles. Second - how do we help you post more of our great local trails? I would be delighted to assist pulling together the information if possible. Thank you! Sep 5, 2013

This is the easiest - and most popular - loop through the park. Once you have mastered this loop, consider adding the more difficult trail sections. The trail map does not include the trail to Vista Overlook - which is the second highest hill in the park and has (as the title suggests) a beautiful overlook of the area. It also has a picnic table in the shade of an oak tree. If you put a route together that has you riding the highest 5 hills in the park - while minimizing repeats - you can ride 17.8 miles in this park while climbing 3000 feet. The ride featured here, which me and my friends call "the lazy loop" has you climbing 1 of the hills. Aug 13, 2018
