Marin isn’t just about the trails. The outdoor scene spills over into the local hangouts—think breweries like Fieldwork Brewing or Pond Farm, where you can wind down and swap stories after a day outside. This blend of adventure and community is a big part of what makes Marin feel special, whether you’re just passing through or sticking around.
Hiking
Some of Northern California’s best hiking trails wind through Marin. The terrain changes a lot, and the views? Pretty stunning. You’ll find something for everyone, beginner to seasoned hiker.
The Dipsea Trail is a local legend, earning a 4.8 rating from visitors. This historic route runs from Mill Valley to Stinson Beach, and it’s not shy about throwing stairs and steep climbs your way.
Mount Tamalpais State Park is the crown jewel for hikers. You’ll find everything from easy walks to tough grinds, and on clear days, the views stretch out to the Pacific, San Francisco Bay, and even the Sierra Nevada if you’re lucky.
Kentfield, Greenbrae, and Ross hug the base of Mount Tam, so you get quick access to a bunch of good trails from these towns.
What should you toss in your pack for a Marin hike?
- Water (at least 1 liter per person)
- Sun protection (hat, sunscreen)
- Layers (weather can flip fast)
- Trail map or a hiking app
- Sturdy shoes
Spring (March through May) usually brings the best hiking weather—wildflowers everywhere, and it’s not too hot. Summer can get foggy near the coast, but inland trails clear up nicely.
Keep your eyes peeled for deer, coyotes, and all kinds of birds. Just remember to give them space and don’t feed the wildlife—no one wants a pushy raccoon.
Most trails are pretty well-marked and easy to follow, even if you’re new around here. A lot of trailheads offer free parking, but the popular ones fill up fast on weekends, so get there early if you can.

The Marin coastline is dotted with beaches, each with its own personality. Exploring them is definitely worth your time.
Rodeo Beach is easy to spot with its dark sand and colorful pebbles. It’s tucked into the Marin Headlands and is popular for surfing, picnics, and birdwatching.

Responsible Recreation and Travel Tips
Getting out in Marin’s wild spaces means helping to keep them beautiful. A little know-how goes a long way in protecting these natural areas and making sure everyone stays safe, no matter the season.
Leave No Trace Principles
Whenever you hit Marin’s trails or parks, stick to Leave No Trace basics. Look up your route and check park rules before you head out.
Keep to designated trails—it helps protect fragile plants and keeps erosion in check. Marin’s ecosystems can take years to recover from even small damage.
Pack out everything you bring, even food scraps. Stuff like orange peels doesn’t break down as fast as you think, and it can mess with local wildlife.
Watch animals from a distance. Feeding them changes their habits and can get dangerous for both you and them.
Try to keep things quiet out there—wildlife (and other people) appreciate a little peace and quiet in nature.
Seasonal Safety Guidance
If you’re hiking in summer (June-September), get an early start to dodge that relentless midday heat. Mount Tamalpais, for example, can feel brutal under the sun—shade is scarce up there. Honestly, don’t skimp on water; two liters per person is the bare minimum for anything more than a stroll.
Winter (December-February) usually means rain in Marin. Trails turn muddy and slick, making each step a little dicey. Stormy days? Best to skip the woods—falling branches in places like Muir Woods aren’t worth the risk.
Spring (March-May) is all about wildflowers, but it’s also tick and poison oak season. Long pants help, and it’s smart to check for ticks when you’re done. If you don’t know poison oak’s “leaves of three,” maybe take a minute to look it up—it’s not something you want to brush against.
In fall (September-November), the weather feels just about perfect for hiking, but fire danger goes way up. Always double-check fire restrictions before lighting up a camp stove, and if you see smoke, don’t hesitate—let the park authorities know right away.
