About This Home

As of February 2026

Nestled down a private lane, 23 Monte Cimas offers an exceptional blend of privacy, tranquility, and access to nature. This charming 2-bedroom, 2-bath home sits on a sunny, oversized double lot, providing a peaceful retreat just moments from premier hiking trails. The thoughtfully designed layout features two spacious primary suites - one upstairs and one down -- plus a bonus room, perfect for home office or additional living space. The generous living and dining spaces feature exposed open beam ceilings and hardwood floors, peek-a-boo views, and easy flow to decks connecting the interior to the natural beauty beyond. The lower level opens to the bucolic yard and magical spaces for gardening, entertaining, or just enjoying nature. There are two fireplaces, and an attached one-car garage. Immerse yourself in the quintessential Marin lifestyle with hiking and biking trails, Muir Woods, and Stinson Beach just a stone's throw away. The shops and restaurants of Mill Valley are an easy drive or hike down the hill, and there is quick access to the freeway and San Francisco as well. A very special opportunity, don't miss it!
