Weird day trips from Boulder

The strangest Boulder finds are often a short drive out. These 5 day trips — Estes Park Memorial Observatory Open House, Trail Ridge Road Night Sky Tour (Estes Park Adventure Tours), Jackson Lake State Park Dark Sky Stargazing and more — are each hand-vetted and sourced: ghost towns, hot-spring soaks, roadside oddities, and odd small-town museums worth the gas. A weird day trip is its own kind of date.
