We took the Tonsina Coastal Trail as far as we could go. It was high tide and there's a bit that becomes completely submerged and inaccessible. It's a gorgeous walk up the wooded cliffs, into a field of wild irises (!!), through a soft mossy forest, past a clear deep stream, and then down to the windy pebble beach.
The sun didn't go down until 11 pm, and even then it was still light. We caught the sunset in Turnagain on our way home around 10.
