About this Event

In the 19th Century, the northern foothills of Mount Diablo were home to the most important coal fields in California. Today, the once bustling mining towns are gone, and the area is one of the parkland gems of the East Bay Regional Park District.

We'll hike the Chaparral Trail to see spring flowers, view groves of Coulter Pine trees, and marvel at 50-million-year-old trace fossils in the rock along our route. We’ll also visit the historic Rose Hill Cemetery, the final resting place for many of the coal miners and their families, including town matriarch and midwife Sarah Norton, whose ethereal spirit is said to haunt these hills.


TOTAL DISTANCE

This is a moderate 4-mile round-trip hike with a 500-foot elevation gain.


LEADER

Lily Parry.


WEATHER POLICY

Rain cancels.

COST

There is a $5 per vehicle park entrance fee.

WHERE TO MEET

We'll assemble at the upper parking area at the end of Sommersville Road. There is a restroom nearby.

NOTES
