The hardest part about this walk with BridgeClimb was finding the place, luckily we had a local who showed us right to the front door. I would recommend giving yourself an extra few minutes before your tour to get there, worst case scenario is that you get there super early so you can enjoy a coffee at the in-house cafe or browse the gift store which has plenty of souvenirs.
There are multiple tour options you can do, from samplers, to the full thing, to mandarin speaking trips, and you can even go up at twilight or night to see the city lights. We chose the full tour, it lasted 3 hours, the first being mainly about safety and getting our gear on. With over 3,000,000 people who had walked the steps before hand, we knew safety was in the front of the staffs minds.Once up on the bridge, there were breathtaking views, the walk itself was not taxing at all, and in fact, a 100yr old lady has done the walk, so no excuses!The total walk is about 1.6km, but the views are so breathtaking that you feel like you haven't walked a step!
Our tour guide was Kate, and couldn't recommend her enough. Full of knowledge, enthusiastic, and remembered everyone in the groups names!
Negatives; I found it hard to pick the experience apart too much as it was a well run, well oiled machine. If I was brutally honest, the only negative would be the price which was $258 for the day climb (more expensive for twighlight/dawn climb, and cheaper for the sampler and at night). In saying that, it is one of those things you do once in your life and you will never forget that you've climbed one of the most famous bridges in the world, so it is worth the price.
