The dog-friendly Lagoon Valley Loop trail circles the lake at Pena Adobe/Lagoon Valley Park in Vacaville. The loop is just over 3 miles long and is relatively flat with gorgeous views of the lake and surrounding rolling hills.
Dogs are permitted provided they are on a leash. Coyotes have been spotted in the area; be cautious and follow leash laws. Long pants are recommended on this trail due to spiky plants where the path narrows. The route is not well-marked, so it’s best to use an app like AllTrails.
Parking fee applies, pay at the kiosk.
