The hike to Mount Perry along Dante's Ridge is easily the most underrated in Death Valley National Park. The easy-to-follow trail follows a ridge along the Black Mountains, offering jaw-dropping views into Badwater Basin and as far as Mt Whitney and the Sierras.
This is a rugged and fairly remote hike. Don't expect to see others and prepare for the conditions, which are often windy and exposed.
Even though it's cooler at this altitude than lower in Badwater Basin, it can still get extremely hot here. In the winter it can be freezing but don't expect snow. In the summer, temperatures can be deadly. Checking the weather and conditions before you do this hike is critical.
Bring at least 3L of water when it's warm out.
The trail is rocky and overall in good condition. Trail runners are a good choice for footwear.
There is intermittent cellular service along the route but nothing dependable. If you have a satellite messenger, I'd bring it.
Osprey Hikelite 26Lightweight, carries all your gear, and your back doesn't get sweaty. Oh yea, it's also one of the most inexpensive packs you can get.
Badwater Basin is the lowest point in North America at -282 feet. During the last Ice Age there was a massive lake there called Lake Manly. The water dried up about 10,000 years ago but occasionally heavy rains will create mini-lakes in the basin.
