I live within walking distance of Reed, and as long as you’re in town looking at PSU and Lewis & Clark I’d recommend thinking about if Reed may be worth a visit just for a different “flavor” of school? Basically PSU, L&C, and Reed are in a triangle, all about 15-20 minutes from each other.
PSU is very urban, and can feel though a lot like a commuter school; great ties to the hospital OHSU, quite good in other areas, but also lots of non-traditional students: busy people in their 20s-30s taking classes and not sticking around, and also some high schoolers who are doing a dual credits situation. They do however have an honors program and separate dorm and structure for those students which is worth looking at if that may be a fit. (If you’re there on Saturday, the PSU Farmers market is held 9am-2pm in the park blocks in the center of campus; it’s the largest farmers market in the city and a great place to walk through and grab some food.)
Lewis & Clark is in a residential, hilly part of town, farther afield, a nice campus and far more of a traditional LAC feel - there’s a wonderful old growth forest (Tryon Creek State Park) quite close by, but you do need to hop on a bus or drive to get “into town;” where it’s located there just isn’t a place to really hang out nearby.
Reed is also in a residential neighborhood, is more stately looking yet also has Reed Canyon running through it (ducks, herons, trails, ponds, wetlands and creek). While it is also in a residential neighborhood, this one is different - it has two walkable shopping/café districts very close by and it’s also closer to the center of town with a lot of easy bus options plus the Max (light rail) line a couple blocks away.
I’m not sure when you might be planning a visit - but I’d really recommend waiting until a little later in the spring. January and February is just in the middle of the dark, wet and gloomy period here, and if you’re looking to help her get in engaged in the process, maybe wait until the flowers start budding out and things look cheerier - at least late March? April would be even better - all the cherry trees start popping. Then, even if it’s drizzling, at least the flowers will be out and things will feel more nice and approachable, it won’t be dark so early and you’ll be able to walk around more easily and the food carts will be busy and people will be out and about.
Happy to answer any questions if this feels useful!
