Getting clinical experience during the school year depends on having a hospital nearby (or a doctors office or clinic - you’re talking about shadowing?) Summers and breaks are there for shadowing otherwise, if you can find them near your home instead.
Kids at LACS do research in summer and during the year, and students from any school can apply to pre-med summer opportunities like REUs at their own or other colleges and hospitals.
The study abroad vs pre-med thing really is the same no matter where you go to school because pre-med required courses are determined by medical schools, not colleges. If you take your one year physics, one yer Bio, two years Chem, one year math, etc on your own campus then you can go abroad and do just language or electives. Any good school - LAC or otherwise - will have pre-health advisers who can help you plan your schedule and figure out a way to include a semester or year abroad in it.
