The Fullerton Loop: Complete Trail Guide for Local Residents

For residents of Sunny Hills, Raymond Hills, and Golden Hills, North Fullerton’s famous unpaved path system isn’t just a recreational park — it’s an extension of their custom backyards. The crown jewel of this network is the Fullerton Loop, an 11.2-mile contiguous multi-use trail system.

Whether you are an ambitious mountain biker, a morning jogger, or an equestrian rider seeking native California woodland shade, navigating this loop smoothly requires understanding specific entry points, local path rules, and the unique terrain blocks that define Fullerton's hillside trail heritage.

1. The Golden Hills Pipelines: Hiltscher Park Trail

If you reside in the Golden Hills neighborhood, your main conduit is the spectacular Hiltscher Park Trail. Stretching across 16 flat, shaded acres of unpaved pathway, Hiltscher runs parallel to Golden Hills’ western ridge, linking directly to the Hundred Oaks Trail Native Garden.

This stretch features active split-rail timber fencing and serves as an equestrian corridor. For hiking and trail running, Hiltscher is considered the most accessible, family-friendly segment in the entire loop as it is wide, protected from vehicle traffic, and heavily cooled by old-growth California Sycamores and Pepper tree lines.

2. Winding Through Sunny Hills: The Robert E. Ward Nature Preserve

As the trail cuts north toward the Sunny Hills community, the terrain shifts from lush village gardens to open California sagebrush and rugged volcanic ridges. The Robert E. Ward Nature Preserve covers critical acreage off Laguna Road, preserving the native flora and wild mustard fields of historical Coyote Hills.

This segment has dramatic, short-burst climbs that reward hikers and athletic mountain bikers with stunning views of the Sunny Hills custom estates. If you are entering from Lagrange or Laguna Road, this is where the trail takes on an authentic wilderness character. Be sure to stick to marked routes to protect local nesting ecosystems.

3. Raymond Hills Trail Connections

While Raymond Hills borders the eastern end of the Coyote Hills Golf Course, local residents can easily tie into the loop via the Panorama Trail or the Coyote Hills Trail pipelines. The elevation here presents winding paths overlooking distant valley views, perfect for a peaceful sunset walk as the lights across North Orange County begin to shimmer.

4. Rules of the Trail & Local Etiquette

Because the Fullerton Loop is highly shared, following unified trail etiquette preserves the rustic community harmony:

• Yield Protocol: Mountain bikers must yield completely to both hikers and equestrians. Hikers yield to equestrians.
• Equestrian Safety: When approaching a horse, slow down, call out of your presence early in a calm, soft voice to avoid startling the animal, and yield to the downhill/outer pocket.
• Pack It Out: There are trash receptacles located at major entry parks (such as Hiltscher Park trailhead and Clark Park). Keep the pathways crystal clean.
