Field Trips

Marin Audubon Society is providing a full schedule of free field trips for the 2024 season.

Advance registration is required for most of our trips, nearly all which have size limits to prevent overcrowding. Registration on the MAS website’s Field Trips page will open ten days before the trip date. 

Trips can fill up quickly. Please register early to make sure you get a spot. If you won’t be able to attend a trip that you have registered for, please cancel using the “contact organizer” button on Ticketbud so that the spot may be opened up for someone else.

Attention: Recently Ticketbud has not opened for trip signups precisely at 8:00AM. This has led to confusion among would be participants who assumed the message “There are no tickets available at this time” means the trip is already sold out, but it doesn’t, so please try to sign up again a minute or two later. Ticketbud is working on the problem.

Our field trips are free to our members and the public, but we greatly appreciate your donations to support our programs and conservation projects! A donation of $35 or more qualifies you for an annual membership at Marin Audubon Society! **New Members Only
