⚡ EV charging nearby
Nearest charging: 2.8 mi — none of the stations on record within 25 mi is identified as DC fast, so arrive with range to spare.
Distances are straight-line, not driving — the road can be much longer where a river, a lake or a canyon sits in between. From OpenStreetMap — community-mapped, so plug types can lag reality. Verify on your charging network’s app before counting on a charger.
