This isn't something we would have chosen to do but we got it because if was the only way to get Alcatraz tickets!
Still, glad we did because the tour was fun and showed us aspects of the city that we probably would have missed on our own.
Lina was great guide. Fun and engaging, although I'm sure she was trying to ditch us and another couple at crosswalks! 😜
The walking isn't hugely strenuous, although when we booked it we missed the fact that it was 4 hours. May be something to consider when booking.
