Description:
The Jeffrey Open Space Trail is short but sweet. Today there is a delightful one mile segment running along Jeffrey Rd. from Trabuco Rd. up to Irvine Blvd. In time the City of Irvine plans to extend it from the Quail Hill Trailhead just south of the 405 Freeway up to Portola Parkway, about 4.5 miles, and beyond to something called Gateway Park (not there yet).

The JOST is a well-landscaped concrete bike/walk trail which winds thru small hills and large lawns with interesting side paths. It undercrosses Bryan Ave. where, just above, the Venta Spur Trail overcrosses. The most interesting aspect of the trail is the history. A series of intaglio panels are set across the trail at intervals, visible from space.

These trace the history of the Irvine Ranch from the Rancho era (Irvine Blvd. end) to the 20th Century (Trabuco end). Take your time and enjoy tracing the history of this remarkable ranch. Don't worry about speed. As soon as you get up to speed, you zip over another panel. Hit the brakes, back up and read on. When you reach the far end, you can blast back to the start.

This should be a fun trail for a family outing. Today it connects with the Venta Spur Trail. When finished (20 years?), it will connect with a number of others from the Hicks down to the Shady Canyon Trail at Quail Hill.

The Jeffrey Open Space Trail - history under foot.
By toolbear in February, 2010

This is a bit different for a bike trail. It’s also a history trail.

At intervals down the trail inset intaglio panels present various aspects of ranch history. If you start at the upper end at Jeffrey and Irvine Blvd. and ride south, you trace the history of the Irvine Ranch starting with the Mexican Rancho era on the north end and ending with the military bases on the ranch from 1914 to the Ligher Than Air station and El Toro Marine Corps Air Station. In between are panels covering such themes as: The JI Ranch – 1864-1876, The Irvine Ranch – 1886-1894, The Railroad arrives – 1887, Myford becomes Irvine, the General Store – 1911-12, The Need for Water – 1890-1961, Michelson’s Measurement – 1921.

It would make a nice family ride. It’s a high speed trail – but only connects to the Venta Spur – which is distinctly low speed. When the whole length is finished from Quail Hill to Portola and beyond, it will be busy.

The first time out, it’s hard to get up to speed. Soon as you are moving, you zip over another panel. Stop, back up, read the display. Reading the panels is not that easy. Getting a good photo of them is harder. You need the right light – and a broom. There is not much contrast between the surface and the inscription.

Take your time, read the exhibits, then go back and ride it straight thru. It’s a short mile ride across what was probably once a lima bean field or orange grove. One suspects the hills you see were put there. The surrounding land is flat as a table. They certainly did a nice job on the landscaping. Looks good from Google Earth. The trail moves in sweeping curves from one lawn to another while a decomposed granite jogging trail curves the other way in counterpoint. Something of a double helix.

There is a nice restroom of fieldstone with water, bench and bike rack at GE: 33.703686° -117.754061° in the upper third (“Great Lawn”) section. Trailside water and seating are on the other side of Bryan Ave. There is no parking associated with the JOST. We used the excellent Woodbury Community Park on the Venta Spur as the trailhead. It’s about 0.3 miles up Bryan Ave.


Ride on!
