Castine is 16 miles south of U.S. Route 1. Turn south on Route 175 in Orland (east of Bucksport) and follow it to Route 166, which winds its way to Castine. Route 166A offers another, alternate route along Penobscot Bay.
Castine lacks a formal information center, though the clerks at the town office (tel. 207/326-4502) are often helpful with local information. (Don't abuse this privilege, though, since they have actual work to do running the town.) The town office is open Monday to Friday from 11am to 3pm. The Blue Hill Peninsula Chamber of Commerce handles tourist inquiries in a more formal manner.
