Visitor Comments About Sonoran Desert National Monument

Just make sure you bring plenty of water and a high-clearance vehicle—the roads can be rough but the solitude and scenery are worth it!”
“As someone from a tropical country, the Sonoran Desert was unlike anything I’d experienced before. The vastness and silence were almost spiritual. We visited in March and were lucky to see wildflowers blooming everywhere. The night sky was incredible too—I’ve never seen so many stars!”
“Table Mountain Trail was challenging but offered amazing views of the entire monument. We camped at Margie’s Cove and had the place to ourselves. The desert comes alive at dawn and dusk with wildlife. Just be prepared—we underestimated how cold desert nights can get in February!”
