NOTE: We register field trips for each upcoming season, so you may not see availability more than three months ahead. For later visits, please join our waitlist and you will receive an e-mail when registration opens. Staff-led trips take place Tuesday through Friday. Self-guided trips take place on Mondays and Fridays. Please select a self-guided trip option to see availability. If you don't see an option that works for you, please email email@example.com and we will do our best to accommodate you.
