We recently went to check out Fields Bridge Park in West Linn, stop 22 on Oregon's Mt. Hood Territory Heritage Trail.
No, you cannot see the Willamette Meteorite there; it resides in the American Museum of Natural History in New York.
The walking trails criss-cross a little more than usual for parks, I believe so that all of the relevant points can be hit. The numbered map of the sites is repeated in a few locations. The "heritage trail" aspect is well-developed here.
Otherwise, it is a nice park, with a playing field, a large community garden space, and an interesting playground.This includes basketball hoops with adjustable height, so with a little bit of customization, anyone can dunk.
And all the while, you can hear the river rushing by.
(I enjoyed that, but it is a reason to keep an eye on children. Dogs are allowed, but on leash.)
There are currently some renovations planned, including a canoe/kayak launch.
At this point I would say benches are not well-maintained. Even those with no missing boards were very mossy. However, more renovations may address that.
Accessability: The playground is not particularly accessible, which seems like a missed opportunity. Accessible bathrooms are available, and the paths are mostly level and well-connected, though there are a few rough spots where roots are growing underneath. That requires some attention.
COVID: Everything is outdoors, and maintaining distance was easy, though that might be less true if attending a game or using the picnic shelters. Use your best judgment.
