From the starting point along Lake (in Oceanside), or College (in Carlsbad, where the new Carlsbad High School is being built), you can get to the top of MT. CALAVERA in 30-45 minutes depending on how leisurely a hike you want it to be.
There are some pretty steep parts (I would not personally describe it as an easy hike but moderate, but that’s my opinion). Be sure to take water and your camera.
