The Ring Mountain Open Space Preserve is a small area located in Marin County, just off highway 101 next to Tiburon. The main reason to hike here are the wonderful views of the San Francisco bay, but even in this drought year we were able to find a nice variety of spring wildflowers.

There are several trails and fire roads in the Ring Mountain Open Space Preserve, supporting a mixture of hikers, bicyclists and equestrians. The Phyllis Ellman trail, on the north side, is limited to hikers, and this is the route we took. For a detailed map of the Preserve see the Marin County Parks map for Ring Mountain.
I always like trails that start off going uphill and then finish with you coming down, and this fits that bill. The trail is a moderately strenuous hike from the bay up to the top of the mountain (Ring Mountain is only about 600 feet high), with wonderful views of the Bay to the north and south. Then you head back down. The area is criss-crossed by a large number of trail branches and loops, both marked and unmarked, so it can be confusing. It is easy to work things out, though – just keep going uphill until you get to the top! There aren’t a lot of trees here so you won’t lose your way.
The trail goes up a fairly exposed hillside so it often is very windy – and it might get hot. There are a few clumps of trees along the way, but your hike will be out in the sun. Keep your eyes open, there can be flowers anywhere in the grass, by the rocks, along the stream. This year, with so little rainfall, the plants were low and sometimes hard to see.
There are so many wandering paths that it is hard to determine how long our hike was, but I’ll guess that we went about 3 miles round trip. The views from the top are wonderful! San Rafael Bay and the Richmond-San Rafael bridge to the north. Richardson Bay and Sausalito to the south, with San Francisco off in the distance (if the fog and clouds cooperate).
Turtle Rock, at the top, is very popular for bouldering, and this also is a popular area for people walking their dogs. Don’t expect to have it all to yourself.
Timing is Everything
Since this is such an exposed area I would expect the wildflower season to be short. We hiked in the early part of March and there was a nice variety of flowers, but for the most part you had to look closely to find them. Other than the Buttercups, which were scattered all over the hillside. Many plants were just sending up heads, so the bloom should extend over several weeks. However, this was a very dry year so I don’t know if this is typical. I wouldn’t want to be out here in the middle of the day when the weather gets warmer, and I wouldn’t want to be here if there was a lot of fog or low clouds to obscure the wonderful views.
Please feel free to help me with the identification of any “unidentified” flowers listed here, as well as correcting any errors I may make. Click on any photograph to see a larger image. I’ll start with a few favorites, and then the “gallery”. All pictures were taken with a Nikon D50 with a Nikkor 18-135mm zoom lens, or a Nikkor 60mm closeup lens. It was a windy day, which made it difficult to get pictures.
My favorite flower on this hike was the Oakland Mariposa Lily. Very low to the ground, a little larger than a quarter.
Fremont’s Star Lily could be found tucked back against some clumps of trees. An alternate name is Fremont’s Death Camas, as this is very toxic.
Shooting Stars are very delicate and don’t last long, particularly with the wind. There is a seasonal stream, and we found them close to that.
Iris were just starting to show, it looks like there may be quite a few later in the season.
