FOAM reaches out to the Humboldt Bay community by offering free Marsh tours, curating a monthly art show, and scheduling free lectures to raise public awareness of the Arcata Marsh.

Weekly and Monthly Tours

Postponed due to COVID until further notice. Ninety-minute tours of the Marsh leave the Interpretive Center every Saturday at 2 p.m., rain or shine. Tour leaders are volunteers recruited and trained by FOAM. FOAM also offers a one-hour, “slower-speed” tour the last Tuesday of each month that leaves from the first parking lot south of Samoa Boulevard on South I Street.

Art Shows

Postponed due to COVID until further notice. FOAM has curated art shows at the Interpretive Center since 1999. This changing exhibit showcases local wildlife and landscape artists and photographers. Artists interested in participating should consult Guidelines for Showing at the Interpretive Center.


FOAM sponsors free public lectures, usually on the third Friday of the month, on Marsh-related topics. During COVID lectures are available on Zoom. Check the Events Calendar for links.
