Sevenmile Slough · Isleton, California
Twenty acres on the riverfront, about an hour from the East Bay and Sacramento. Park the boat, slow down, stay a while.
Tucked away amid the quiet waters of Sevenmile Slough, just off the San Joaquin River, with 20 acres of open green space, an abundance of wildlife, and views that feel never-ending. The tempo here is slower, an atmosphere that fosters relaxation, ambling walks, and the enjoyment of simple pleasures.
A beautiful riverfront setting in the California Delta, just minutes from Isleton and Rio Vista. Easy vehicle access via Delta Highways 12 and 160, a straight shot from I-80 and I-5, about an hour from the East Bay and Sacramento. By vessel, we are at channel marker 41 with no draw bridges to contend with.
A slower, easier pace on the water, with the amenities families enjoy.
