Note: Reservations are required. Reservations are limited to a maximum of 55 visitors per tour. Reservations are on a first-come/first-serve basis. Once the maximum number of reservations is met, we cannot accept any more reservations for that tour date. No guests will be allowed on-site without a reservation. For groups of 5 or more, please call (951) 928-3777 x4226 or send an e-mail to freetaga@emwd.org
