Rolling Hills easy access to great hiking in Orange County Entering the Chino Hills State park from the south Entrance at Rim crest Dr. puts you right in the middle of a great park with an abundance of wildlife and scenery. The hike starts off on the south ridge trail from Rim crest dr. Hike west along the south ridge trail as it allows you views of Orange County. At about 2miles, the road forks. follow to the right on Diemer trail. Diemer trail winds down the hill for about a quarter mile. At the bottom, head east on Telegraph Canyon back 2 miles until you see the trailhead for easy street. head south on easy street trail and back to Rim crest dr. The ridge portion offers scenic views but little shaded areas. Telegraph Canyon offers great shaded areas to stop for a snack and cool down. The easy street trail a smaller trail that is off limits to mountain biking, but still be aware as bikers tend to ignore this rule. Easy street is also a moderately steep climb just over .3 mile.
On a clear day after the rain, was able to see panoramic views all the way to Catalina. If you start the trail going left from the trailhead, it's an easy to moderate level of effort.
Good trail...the inclines were steep and if you are out of shape they take a toll on you, but when you have completed any of the trails...you will feel like you worked out!
great scenic hike.
Good distance hike. My 7 year old son was able to complete the trail with little trouble.
