Agree museum is a good one. Also simply don't ever get caught on the bar at max ebb.
For those with some time to spend playing the river is easy. Cross the bar at low slack and use the flood to get into Astoria. Spend the night, or longer, and enjoy (and rest after the previous passage). Then leave Astoria at low slack and head
upriver to Cathlamet, Washington
, on the flood. Spend the night there - nice small town. Then grab a low tide and work up to St. Helens, stay at free dock
and go out for dinner. Next day motor
up Multnomah Channel (not main channel) and enjoy beautiful trip without ships. There are free places to stay in the channel (state parks). OTOH a lot of racers coming back from the Oregon Offshore
and Swiftsure just brute force the trip - part of the difference in cultures.
I'll take a look at the wiki.
