Haverford looks smaller than it is. It shares campuses with Bryn Mawr. BMC / H are twin campuses and do virtually everything in coordination. Plus they can take classes at Swarthmore and UPenn.
Women’s colleges vary in how many men they have on campus. BMC clearly has men on campus as its co-campus is Haverford. BMC also has some grad programs which include men. Getting to Philly is easy. BTW BMC’s geology program is well known and remarkable–noting because of the environmental interest you mentioned.
Similarly Smith is in the middle of a cute small town and part of a consortium that includes co-ed schools. Free buses take the students around. Dorms at Smith and Mt. H allow overnight male guests. I personally like Mt. Holyoke a lot, also part of the consortium. I prefer it to Smith.
Barnard’s co-campus is Columbia and there are men there as well. NYC is on a body of water that has a lot of interesting environmental efforts in progress, especially with oysters. The campus of Barnard / CU really is the entire city.
As for Vassar being “not an urban school” --that’s false. It’s in Poughkeepsie, albeit pushed a little to the side in a more suburban-looking area. You could avoid the city part of Poughkeepsie if you choose to, but P-town offers a lot in terms of providing music venues, restaurants and internship opportunities and even real jobs upon graduation. P-town is also on the MetroNorth commuter line to NYC, which means students can go to NYC as a day trip. Vassar has strong sciences and humanities in addition to the arts, as noted. Vassar’s studio arts program is not as well developed as Haverford’s/BMCs (they share an art department). Vassar is also in the Hudson River Valley, which is lovely and offers abundant nature.
I echo the idea of U Puget Sound–it’s an under appreciated school IMHO and about to be “discovered” I predict. I sense that it’s becoming a “hot” school because it offers so much. And it’s more reasonably priced than similar schools on the East Coast. UPS is in a cute town, solid academics that I estimate are on par with perhaps Connecticut College, on a body of water, Mt Rainier visible in the near distance, close to a major airport with transportation to the campus from there. While it has team sports, the student body seems active in outdoor sports - kayaking, hiking, camping, etc. The orientation activities seem to involve these sports–and a few indoor things as well. I personally like the Hawaiian cultural activities, which speaks to its connection in that direction.
Another school that’s often on people’s list, is UVM. It’s a public school, outdoorsy, and larger than some of these LACs. The town is also adorable, with an airport. I want to also then draw your attention to U of Maine at Orono. It has many of UVM’s features but offers a lower price. The campus is attractive, has a nearby airport, offers nearby National Park (Acadia) and other outdoor sports. The school is offering matching in-state tuition for many states and reduced tuition for the others. The school has excellent (excellent) marine sciences and ABET-accredited engineering. In other words, the academics depending on the department can be top notch.
