01
Best overall pick
Sweetwater Regional Park Trails
Central Bonita • Riverfront Regional Park With Rolling Hill Trails • Best Overall Hiking Hub
A versatile network of dirt paths and fire roads follows the Sweetwater River right in Bonita’s backyard.
Trailheads around the Sweetwater Summit area let you stitch together everything from quick leg-stretchers to half-day loops along the river and up onto low ridges. Expect mellow grades, open views, and a mix of walkers, runners, horses, and occasional bikes. It is a great place to learn the local terrain and have a reliable go-to hike close to home.
02
Best water views
Sweetwater Reservoir to Cactus Hill Trail
East Bonita Near Sweetwater Reservoir • Open Lakeside Route With Gentle Climbs • Best For Big-Sky Views
An out-and-back along the south shore of Sweetwater Reservoir with wide-open water views and a short climb toward Cactus Hill.
This stretch of the Sweetwater Reservoir Riding and Hiking Trail trades shade for space, with broad vistas across the lake and low coastal hills. The path is mostly smooth and gradual, making it a good choice for relaxed pacing or golden-hour walks. Bring sun protection, as the route is exposed and you will often share it with equestrians and cyclists.
03
Shadiest canyon walk
Rice Canyon Trail
North Bonita Canyon • Shaded Riparian Canyon Path • Best For Hot Days
A surprisingly lush canyon walk with pockets of shade tucked just a few minutes from Bonita’s main streets.
Rice Canyon offers a narrow dirt trail that winds along the creekbed under willows and other riparian growth, giving it a cooler, more secluded feel than most nearby routes. Short ups and downs keep things interesting without ever becoming strenuous, and the setting works well for leashed dogs and steady kids. After winter or spring storms, expect mud and a more rugged feel underfoot.
04
Best easy mileage
Otay Valley Regional Park
Chula Vista – Otay Valley • Urban Greenbelt With Wide Multi-Use Trails • Best For Relaxed Distance
Flat, family-friendly paths trace the Otay River through a long green corridor between Bonita and south Chula Vista.
Multiple staging areas let you pick a short out-and-back or stack segments into a longer walk without much elevation gain. The wide decomposed granite tracks pass ponds, meadows, and restored habitat, so there is usually birdlife to watch even on busier days. It is ideal for strollers, first-time hikers, or anyone wanting easy miles, though shade is limited so earlier starts are more comfortable.
05
Classic San Diego summit
Cowles Mountain at Mission Trails Regional Park
Mission Trails Regional Park, Northeast Of Bonita • Steady Summit Hike On A Rocky Singletrack • Iconic Local Peak
A popular 3-mile round-trip climb to the highest point in San Diego city limits with sweeping coastal-to-mountain views.
Though it requires a short drive from Bonita, Cowles Mountain is the closest true summit hike that feels like a mini adventure. The well-defined trail climbs steadily over rock and hardpack, rewarding you at the top with a 360-degree panorama that takes in downtown, the bay, and the inland ranges. Go early or near sunset to avoid heat and crowds, and plan on limited parking at the trailheads.
