15The Cave of the Bells
This cave, nestled in Coronado National Forest’s striking Sawmill Canyon in Patagonia, provides perhaps people with the state’s most fun spelunking experience. You have to hike for four miles up a dirt road to reach this place. If you’re not feeling athletic, drive a high-clearance or 4WD there.
Believe it or not, the inside of the cave is actually warm. There’s also a permanent lake not too far from the cave entrance. This underground lake is roughly 263 feet below the surface. The official lake tunnel entry leads to this well-known underground lake.
Strangely, the deeper you hike, the warmer the temperature of both the air and the lake. Experts say this happens because there is actually some heat source under the surface of the lake. Be aware that, just like Onyx Cave, the entrance to this cave is gated and locked.
Due to this cave’s extremely delicate environment, travelers must contact the Coronado National Forest Supervisor’s office, make reservations, and leave a deposit of $100.00 to get the keys. When the gate keys are returned, the deposit is refunded.
