This beautiful counter-clockwise loop heads north from Duncans Mills and Cazadero to the challenging climb up Kings Ridge Rd to Tin Barn and Skaggs Springs Rd. It climbs out of the dense coastal redwoods to Stewarts Point followed by a gorgeous 27 miles stretch along the stunning Sonoma Coastline to the Russian River at Jenner.

Begin this ride from B St at Duncans Mills.

Turn left onto CA-116 E; it rolls along the Russian River with views of the forested Sonoma Mountains to Cazadero Hwy.

Head north on Cazadero Hwy; the flat terrain on this road takes you along Austin Creek through the towering redwoods and residential community.

Cazadero Hwy winds its way along the creek through the center of Cazadero to King Ridge Rd.


Kings Ridge begins on gentle terrain for the first 2.6 miles as it heads north through a small pocket of homes to the dense woods along Austin Creek into Holmes Canyon.

After first bridge crossing, the road kicks up for a 0.6 mile climb with an average grade of 8.5% followed by a mile long descent to the next bridge crossing over Austin Creek.

From here, the road tilts up for a steady climb for the next 1.3 miles as it weaves its way to the first sharp switchback; the average grade is 10.4 % with steep pitches of 12-14%!

The road exits the woods out to the back ridge and levels out to the iron gate at mile marker 10-the first summit. Enjoy the surrounding mountain views!

From the gate, the road drops down for half a mile back into the woods and onto uphill rollers for the next mile-average grade 4.5%.

The road descends for a very short bit followed by a 0.7 mile steep climb with 13-16% pitches at the switchback and an average grade of 11%!

You’re near the top of the ridge when the trees lead out to the open skies ahead.

This is the part everyone loves about this road-it’s a grind to get up here but it’s well worth the effort! It’s a whole new world of riding as you roll along the top ridge line with expansive views of the surrounding dense variegated forests, open hilltop meadows, vast mountains, and ridges!

This is also cattle country with free roaming grazing cattle and ranches.

The road continues with short rolling climbs along the ridge for 7.4 miles.

The gentle rollers take you across a few cattle guards through the open ranch lands with weathered old barns, wooden cattle pens and old ranch homes.

Kings Ridge Rd ends with a climb out to the junction at Hauser Bridge/Tin Barn Rd; it’s 0.7 mile with an average grade of 4.8%.

Hauser Bridge/Tin Barn junction:

Turn right onto Tin Barn Rd, it continues north along the top of the ridge.

The rolling terrain on Tin Barn Rd takes you through the hilltop meadows and woodlands to the heavily gated Odiyan Retreat Center.

Tin Barn Rd climbs for 0.8 mile with an average grade of 5.1% before descending into Stewarts Point Rancheria; home to the Kashia Band of Pomo Indians.

Skaggs Springs Rd leads you through the Rancheria to Miller Ridge before twisting down into the canyon to the bridge crossing over the Gualala River. Watch out for the cattle guards!

Skaggs Springs Rd climbs out of the remote shaded canyon for one mile with an average grade of 6.4%; it winds up through the gorgeous coastal redwoods and continues on gentle rolling terrain on a beautiful narrow road to Stewarts Point off Hwy 1.

Cross Hwy1 for a stop at the Stewarts Point Store.

The coastal run on Hwy 1 S to Jenner is 27.2 fabulous miles. The rolling terrain has gradient ranges of 3.5-7%. Take in the magnificent views of the headlands and rocky coast to Salt Point State Park.

Hwy 1 S to Gerstle Cove:

Ocean Cove to Stillwater Cove:

Timber Cove to Fort Ross:

From Fort Ross, Hwy 1 S levels out to the coastal cattle ranch. Watch out for the free-roaming cattle on the road!

Hwy 1 S continues with a series of climbs and descents with gradient ranges of 5-10% from Mill Gulch to Timber and Jewell Gulch. The coastal views are stunning!

Hwy 1 S climbs out of Jewell Gulch to Meyers Gulch with gradient ranges of 5.5-7%; it continues winding along the coast on rolling terrain to the summit at Meyers Grade Rd.

Get ready for a screaming wild descent on Hwy 1 S from Meyers Grade; the road swiftly winds down and around the guardrails on super smooth pavement to Russian Gulch. Keep your eyes on the road-the views can be distracting!

The road climbs out of the gulch for half a mile with an average grade of 6.6%.

Hwy 1 S continues on gentle rolling terrain towards Jenner.

Brief stop at the River’s Mouth, where the Russian River meets the Pacific Ocean.

Hwy 1 S runs through Jenner and continues along the Russian River to CA-116.

The rolling terrain on CA-116 E leads you along the river valley through the cattle ranches and barn to Duncans Mills.

This magnificent hilly route takes you along the remote country back roads around Sonoma County out to the gorgeous Sonoma Coastline. You’ll absolutely enjoy the phenomenal vistas atop King Ridge and the stunning ocean views along the craggy coastline, secluded coves and ragged headlands!
