Upcoming Field Trips
Please join the Marin Chapter of the California Native Plant Society on hikes to see seasonal native plants in the field.
- All hikes are free and open to the public, so invite your friends.
- Beginning plant enthusiasts are welcome on all hikes.
- Come prepared for any type of weather or conditions, dress in layers, have non-slip footwear, and bring rain/wind protection just in case. Although it may be sunny and warm when you leave home, the weather could be cold and foggy when we reach our destination.
- Bring lunch and plenty of water, binoculars and/or hand lenses, and your favorite field guides. Field Trips may have links to CNPS Plant Lists of the area.
- For logistics we allow a maximum of 20 participants on each field trip, less if appropriate.
- Please contact hike leaders with any questions about individual hikes.
