I have visited this site many times & am due again in 2 weeks. The Dart crossing is not a C charge (Congestion zone charge) as stated in the below reviews from May 2017 which may be a little confusing for those that are not familiar with the charges. There is a Dart crossing charge 7 days a week, but not charged on an evening. This is not part of the LEZ area but the site is within the LEZ area so if you do not meet the criteria you would get a charge for entering the LEZ but the bridge is not part of the LEZ. The difference I think is a LEZ charge is around £100 a day I believe on week days where the Dart crossing is £2.50 and cheaper if you have an account. I just wanted to clarify this for visitors.
