Ethel M

Ethel M is the Mars family's premium chocolate brand, and its Henderson flagship pairs a free self-guided factory viewing aisle with a three-acre Botanical Cactus Garden of 300-plus desert plant species, which Ethel M calls the largest cactus garden in Nevada. Both are open to the public year-round at no charge. The catch on the chocolate side is timing: chocolatiers work the line Monday through Friday, 10 AM to 3:30 PM, so a weekend or evening visit means staring at idle kettles. A free sample is a long tradition here but not a guarantee - enjoy it if offered, don't plan around it.

Size your expectations. This is a 30-to-45-minute stop (viewing aisle, shop, garden loop) about 11 miles southeast of the Strip, so it needs a car and works best chained with other Henderson stops. And a correction to the common myth: the beloved winter Holiday Cactus Garden Lights are not free. Ethel M charges entry for its seasonal events, holiday and Valentine's alike, and sends the proceeds to local charities; last season the gate was $3 per person, with 65-plus and under-2 free and a free opening night. The 2026–27 run is set for November 5, 2026 through January 3, 2027, nightly 5 to 10 PM, closed Christmas Day and cut to 5 to 8 PM on Christmas Eve, New Year's Eve and New Year's Day. This season's entrance fee is $3 per person, with children under 2 and seniors 65 and over free. The daytime garden stays free the rest of the year, and so does parking.
