Hillel publishes lists of schools with particularly high numbers of Jewish students, both in terms of absolute numbers and in terms of percentage. Since LACs are small, the latter list is more relevant. The following LACs, with estimated % Jewish enrollment, show up on that list:
33 Barnard
31 Goucher
28 Sarah Lawrence
26 Oberlin
25 Muhlenberg
24 Haverford
23 Hampshire
21 Vassar
19 Skidmore
18 Mitchell
16 Kenyon
14 Bryn Mawr
14 Union
13 Franklin & Marshall
Hillel apparently didn’t have the numbers for Wesleyan University, but Wesleyan is a top LAC with relatively high Jewish enrollment. Wesleyan estimates it at 20-22%.

The Hillel list also includes universities, some of which are relatively small, like Brandeis, Lehigh, Tufts, or Clark.
