Lake Arrowhead, San Bernardino National Forest, California (a signature setting, with many lakeside scenes shot there).

San Bernardino National Forest more generally, used for outdoor and mountain scenery.

Forum / Trending Angle

On classic‑film forums and niche cinephile blogs, the filming question often comes up because fans notice the distinctive mountain lake scenery and want to identify the real place behind the melodrama.

“Was that really some Swiss lake or was it just California pretending again?”

The answer, as with many mid‑century Hollywood dramas, is that California’s lakes—especially Lake Arrowhead and Big Bear—were doing the heavy lifting behind the camera.

TL;DR:
Magnificent Obsession (both 1935 and 1954 versions) was filmed largely at Lake Arrowhead and Big Bear Lake in the San Bernardino National Forest in California, plus studio work at Universal Studios and some extra footage at Venice (Los Angeles) and Lake Tahoe.
