October 12, 2025, Marin Museum of Bicycling

An absolute must-see for cycling enthusiasts! This museum in Fairfax tells the story of nearly 200 years of cycling history, from 19th-century velocipedes to modern racing bikes. It's also home to the Mountain Bike Hall of Fame, featuring unique specimens and stories about the pioneers of mountain biking. The collection is impressive and authentic—no replicas, but real bicycles that showcase the evolution of technology and design. An inspiring place where you can truly feel the passion for cycling.

Mount Tam East Peak offers some of the most majestic views north of the bay. From this vantage point, you can see all of Marin, along with Point Reyes to the north and Oakland and San Francisco to the south. The stunning panoramic vistas make the journey well worth the effort. There are restrooms and picnic tables, ideal for a snack or lunch while you capture some incredible photos.

Often busy on weekends, this is a great spot to take moment before/after summiting Mt Tam. There are spigots to fill up water and bathrooms that are open during park hours. The parking lot is very close for those that drive up. There is access to MANY trails for those on foot/bike.
