Daily Guided Walking Tours "From Saguaros to Tequila Plants" at 11:00 am
Our volunteer tourguides research, study and prepare themselves to answer an array of interesting questions – just ask veteran guide Rich Adams. Guests often ask whether its true that Saguaro cacti grow arms to counter-balance the trunk; what plant tequila is distilled from, whether an extract from creosote bush produces the pungent coating on railroad ties - and if palm trees are native to Arizona. Where does BTA get its water? And how do those massive boulders of volcanic rock stay in place above the ‘Switchbacks’ section trail below Picketpost Mansion? Learn about the Sonoran Desert and hear the answers to those and many more questions on a guided 11a.m. tour; they're included with daily admission of $10 (free, for our BTA annual members), and depart from the breezeway lobby of BTA's visitor center daily at 11am.
