Wear the right shoes. Hiking boots aren’t necessary, but a comfortable pair of athletic shoes are recommended.

Due to the many local microclimates, dressing in layers is best. A walk that starts in cloudy, chilly weather may end under clear skies and temperatures in the 90’s.

Bring a full water bottle and drink before, during and after your hike.

On warm days, avoid hiking mid-day when temperatures are high.

Wear sunscreen even on overcast days.

Stretch before beginning your hike or start out slowly to allow for proper warm up. Know your abilities’ limits and don’t overexert.

Each trail also serves as habitat for local animals and plant species. Be aware of poison oak and wild animals as you hike. General rules of thumb for encountering wildlife:

Don’t intentionally approach animals.

If hiking with a child or small dog pick them up.

Report sightings to the Antioch Police Department.

If you encounter a snake, slowly back away.

If you encounter a mountain lion, raise your arms and make yourself seem larger than you appear, make loud noises.

Lougher Loop Trail

Begin this loop trail from the Sydney Flat Visitor Center, heading east as the trail begins on the other side of Somersville Road.

Not only are the stunning views of the delta present, you will also tour through the Rose Hill Cemetery which has been untouched in over 100 years along with stops through old mining country.

Lower Chapparal Loop
