The Griegos Acequia is my nearest ditch and the one I ride up most often, especially when I just need a 30 minute cardio workout and don't want to load the bike onto the Prius. It flows north to south, like most do and technically ends just west of Valle Lane and my neighborhood of Candelaria Village. What's left continues into Matthew Meadow as the Menaul Lateral.
The northern beginnings of the Griegos Acequia is vague on the MRGCD maps. Map 31 shows the Griegos Lateral coming down from the north behind Los Poblanos, going under Montano Road via an enormous siphon, and arriving at the edge of Dietz Farm. The Griegos Wasteway splits off here and strikes to the west to empty into the Atrisco Feeder.
What water doesn't head down the wasteway flows southeast along an unlabeled section of channel crossing Rio Grande Blvd, going over the Griegos Interior Drain, and eventually being identified as the Griegos Acequia near Guadalupe Trail and Griegos Road. From that point it runs south until it goes under Candelaria Road just east of Valley High School and surfaces in the short section west of Valle Lane.
The Griegos is not only a great local cardio workout, but the gateway acequia to many of my North Valley favorites. Let's peddle north and see how it goes.
I have to bike a 100 yards or so up the sidewalk of Candelaria to reach the ditch by the high school where I cross at the light. The bit to the south deadends at a wall at the edge of Matthew Meadow, so I ignore that, but it's an obvious hangout for students who keep cutting the lock on the ditch gate.
On the north side of Candelaria, the west bank runs behind the auto mechanics shop of the high school into the Broadview Addition, a very normal North Valley neighborhood. The path drops down to cross Cherokee Road. You can take that west to a pedestrian walkway the gets you on Valley Pool Road and points west.
North of Cherokee staying on the west bank one crosses Van Cleave Road and shortly after come to San Lorenzo Avenue. At this point it's easiest on a bike to pop a few yards east to San Clemente and bike a hundred yards until there's easy access to the east bank of the acequia via someone's driveway where the street turns hard right. This avoids hopping a curb and struggling with a rough, narrow patch.
The east ditch bank trail continues behind residential properties (with a side branch going west to Avenida Cristo Rey) until it comes out on Griegos Road at Guadelupe Trail. The traffic volume means extra caution needs be taken when crossing--there is no light.
Most often I ride up Guadelupe Trail to Colombus Park and then return for a 3 mile trip. One can also head further north from the park, cross Montano, and make your way into the Los Poblanos Open Space... but that is another trip.
If one stays on the east bank past Griegos, the acequia runs by larger homes and fields. At one field there are two awkward styles that requires some careful maneuvering to squeeze your bike through the fence. Beyond that, it's an easy peddle curving to the northwest until one reaches the Griegos Interior Drain and its very wide access road.
From here one can go south a bit along the drain to Dietz Place and thence to the Flying Star and other shops at the Dietz Farm Plaza. Continuing mostly west on our acequia, one quickly comes to Rio Grande Blvd. On the west side of the street, the acequia's source is found where the Griegos Lateral bubbles up after passing under Montano and the wasteway tumbles off towards the river.
Total distance from Candelaria Rd to Montano, 1.67 mi (2.69 km).
