The Queen Elizabeth Olympic Park is now open which means that after some years it is again possible to divert east and look at the Bow Back Rivers.
The best entry into the park when walking south is at Hackney Wick where you can go up on to the White Post Lane Bridge and go straight in.
Further south the diversion along the Greenway still affords a good view of the park although it is not so green since you also see the service entrance to the Arena. But the Moka East Cafe (or container cafe) in the View Tube at the end gives a panoramic view.
Here there is easy access to the just relocated Pudding Mill Lane Station.
