Tower Bridge is raised at irregular intervals dependent on when the need to let ships pass occurs (around 1,000 times a year). If you want to see it then check out the schedule of lift times on the Tower Bridge website.
Don’t even try to see this. The people at the scrap yard run me off and won’t even let me take some pics. Had to go to a 3 story building to take my pics.
This park is an interesting one. Seeing as its the newest addition to the NPS, there are absolutely zero services or information when you arrive. You'll likely think you're in the wrong place, but the open space is free range to explore. Definitely go during daylight. Didn't spot any fossils, but I'm sure they're out there somewhere!
I look forward to this every year. The docents are kind and excited about the performances, which are great. I love that I can bring my dog and a picnic basket and blanket and have a nice free family friendly night.
