From US-101 North, take exit 445B to merge onto CA-1 North towards Mill Valley / Stinson Beach. Continue 6 miles on CA-1 North, then turn left on Pacific Way and drive 0.2 miles to reach the parking lot for Muir Beach.
Route in brief: Green Gulch Trail → Coyote Trail → Miwok Trail → Tennessee Valley Trail → Coastal Trail.
Notes: Almost all trails are unshaded. Plenty of wildflowers. There is a short steep hike to a lookout point atop a hill next to Tennessee Beach. The views from this point are awesome! A short steep hike takes you down to Pirates Cove, a small beach. Worthy of a side trip. The section of the hike along Coastal Trail was particularly scenic. There is an unofficial trail near the junction of Coastal Trail and Coastla Fire Road that goes towards the ocean.
