The County of Marin, north of the Golden Gate is primarily a peninsula composed of hills, ridges and small mountains. Some of the "hills" are higher than the "mountains". Most of the populated areas are along the eastern side in the lowlands by the North Bay. The lions share to the west is rolling, hilly ranchland, including Open Space, State Parks and the Golden Gate National Recreation Area as well as Point Reyes National Seashore.
This page attempts to feature a comprehensive listing of all but a few named highpoints throughout the county as well as a few unnnamed ones. Like all mapped geographical regions the naming of features is somewhat arbitrary. Some prominent ones are left unnamed while some insignificant ones are. Most of them are accessible to the public and some are on private lands. Everything is featured starting from the highest elevation to the lowest. Each one also includes what type of land it is on and the accessiblility. The ones with quotation marks are unnamed but given names for this page.
From San Francisco County take the Golden Gate Bridge north.
From Sonoma County Take Hwy. 101 or State Hwy 1 south. From Napa or Solano County take State Hwy 37 above the north bay or take Interstate 80 to the San Rafael Richmond Bridge west.

When to hike and what to expect
Deer Park looking northwest
All of these mountains, ridges and hills can be climbed year round. Even in raging rain storms ripping off the Pacific it can be an exhilarating hike if you've got some simple light weight rain and wind attire. There is seldom lightning accompanying these rainstorms in the bay area unlike the Sierra. In the summer when there is low pressure along the coast the fog tends to move into the county over the hills on the heels of a westerly wind during the course of the night, especially over the Inverness Ridge and the west Marin hills but often burns off by afternoon. The more inland you go the warmer and calmer the weather, If it's hot inland you can go out towards the coast for cooler hikes. On hot summer days it can reach near 100 by mid afternoon. The use of sunscreen cannot be underestimated.
Regardless of the time of year it is always good to bring plenty of water, a snack and at least a windbreaker. No matter how mellow it is at the bottom by the time you get up 1,000 ft or so it can get windy and significantly cooler.
There need not be much concerned for insects. There are virtually no mosquitos but in the summer when your are trudging and sweating up some hot hillside in the sun the horse flies can attack you at your weakest depending on the numbers produced by the previous winters rainfall.
Springtime is the best time with the hills green and wildflowers arriving by March. In summer the hills dry out and become brown.
