CannaBoos Tours
Through October, 8 p.m.

This night of frights and pot-friendly fun starts at Colorado Cannabis Tours headquarters in south Denver, where you'll get free hemp pre-rolls and gummies. Once aboard the tour bus, however, you'll be free to light up any cannabis or hash you bring with you before getting private access to haunted properties in Denver. After visiting a few local haunts, the group will end the tour at 12 Spirits Tavern inside the Patterson Inn, one of Denver's oldest hotels with plenty of ghost sightings of its own. Tickets (21+) are $86.90 each; book online or by calling Colorado Cannabis Tours at 303-420-8687.
Spook-Tacular 420 Ghost Tour
Thursdays through Sundays in October
Downtown Denver
A mobile cannabis lounge will drive passengers around downtown Denver's most notorious haunts and spirits, as well as a few lesser-known spots — but not before stocking up at the dispensary first. After stopping at a pot shop, riders can take their own cannabis aboard the mobile lounge and smoke, vape or eat edibles as guides talk about historical haunts, the city's seedy side and scary events, past and present. Guests can light up in the van, and there are stops around town that involve a little walking. During the walking portions of the tour, guides will use spiritual tracking devices and techniques to gauge ghostly activity, which is pretty frequent in the area, according to Dark Side of Denver. Tickets (21+) are $55.20 each.
