It is one of the biggest bridges I have ever seen or been to in my life. The only gripe I would have is the weather. Most of the time its usually covered in clouds so make sure you plan accordingly. I was in SF for about a week and I only saw this bridge clear as day for one of those days. This was during August. Other than that I highly recommend to rent a bike and to bike across the bridge and explore!
