Accessibility

No Wi-Fi at the campground. Free, public Wi-Fi is available at the Albright Visitor Center.
There is a cell phone tower near Mammoth Hot Springs: check with your provider to verify coverage. The number of people in the busy summer months of July and August can overwhelm cellular circuits resulting in an inability to send or receive a call, text, or data.
Wood and charcoal fires are permitted, though special fire restrictions are occasionally put in place when the danger of wildland fires is great. If you plan to light a fire in the park, please ask about current fire restrictions at the entrance station when you arrive or email our Visitor Services Office immediately prior to your visit. Propane grills and stoves are normally not restricted.
