Castlewood Canyon Lucas Homestead Ruins

Most people drive out to Castlewood Canyon for the collapsed-dam ruins, never realizing a second, weirder ruin sits a five-minute walk from a different parking lot. Patrick and Margaret Lucas — Irish immigrants who met in Arizona and married in 1889 — homesteaded here and in 1898 built a two-story house out of poured concrete, a bizarre choice for a residence at the time, to shelter their eight kids. The family kept it up until a fire gutted it in the early 1960s; now the bare concrete shell rises straight out of the canyon floor. The 0.35-mile spur to it is short, flat, and almost always empty.

The move: Pair the easy 0.35-mile walk to the homestead shell with the dam-ruins loop, bring a picnic, and split off to the concrete shell when the dam crowd thins out — quiet, photogenic, and over in an afternoon.
