Trail Overview: The winding scenic George Miller Trail (GMT) takes you 1.7-miles gate to gate from its west end at Port Costa, to Martinez at its east end. Sitting high above the shoreline it provides spectacular views of Carquinez Strait, Benicia’s waterfront, Mt Diablo, and an active railroad line; you might hear an occasional train pass by. If you’re a manual wheelchair rider and looking for a good workout you’ll find plenty of dips and climbs to build up your muscles. Mature oaks dot the rolling grasslands and a scampering lizard may cross your path.

For an off-road adventure, follow the fire road trail, that when traveling towards Martinez, is located just beyond the eastern trail gate and the roadside parking. It gradually climbs inland along the hillside amongst towering oaks and birdsong filled the air on my early June visit. I personally found this trail more peaceful than the GMT. According to the park’s map it’s the Franklin Ridge Loop Trail although the sign at the gate said Fire Trail. I followed the lower portion of the loop because at the first fork the upper part of the loop climbed steeply. Unfortunately, I had to turn around after ¼ quarter mile so as not to disturb a hornet’s nest.

More Info: There's very few level stretches. At 1.3 there is a tenth- mile stretch that has a 13% grade. Cross slopes on the Fire Trail may be greater than 2% The Fire trail is compacted dirt and may be muddy after rains.
