We got the Cape Perpetua visitor center at 3pm. When asked about Thor's well, the stuff there told me that it's not what you saw on the internet...The low tide for that day was about 4pm and to be honest, we did not find the big hole at first glance. It was hidden near the sea, just next to(like 20m away from) the Cook's chasm. It's not as big as it appears, and only until the tide gets higher(also windy), you can expect to get a good shot of the fallen water. The high tide for that day was about 10pm and the sunset was 9pm, so I couldn't get a perfect big wave to flow all around, with the sunset. This is the best one I've got there.
