Ready to level up? Solstice Canyon offers advanced riders a serious challenge with steep climbs, technical descents, and chunky rock sections that demand skill and fitness.

The Challenge

With a 50/50 split between paved approach and technical singletrack, Solstice rewards the effort with some of the best descending in Marin. A consistent climb leads to a sustained descent that will have you grinning ear to ear.

The Route

  • Approach: Paved road climbing out of Fairfax
  • Climb: Sustained fire road and singletrack gaining 2,400 ft
  • Descent: Technical singletrack with rock gardens, drops, and tight switchbacks
  • Return: Mix of trail and road back to town

Technical Features

  • Rock Gardens: Chunky, loose sections requiring line choice
  • Steep Grades: 15%+ pitches on the climb
  • Exposed Sections: Ridge riding with drop-offs
  • Root Sections: Technical climbing through forest
  • Fast Descents: Speed management crucial

What You’ll Need

  • Fitness: This is a workout - be prepared
  • Skills: Comfortable with technical terrain
  • Full Suspension: Highly recommended for the descent
  • Extra Water: 3+ hours, limited refill options
  • Tools & Tube: Remote sections, self-sufficiency required

Rewards

  • Incredible views of Mt. Tamalpais
  • Epic singletrack descent
  • Sense of accomplishment
  • Solitude - fewer crowds than Tamarancho
  • Wildlife sightings (deer, hawks, occasionally bobcats)

Best Season

Spring and fall offer the best conditions. Summer can be hot on exposed sections. Winter may have muddy patches.

Local Tips

  • Start early to avoid afternoon heat
  • Walk technical sections until you know them
  • Check your brakes before the descent
  • Bring snacks - you’ll need the energy
  • Ride with a buddy - remote trail
  • Tell someone your plans
