Two day rim to rim hike with one night in Bright Angel Campground sounds almost boring but it was everything but...Got our permit as walk ins the day before, reserved our bagged lunches, and dinner at Phantom Ranch, and since we didn't care for being human mules, we had our camping stuff shuttled from the North Rim to the South Rim, where it got delivered to the Phantom Ranch Duffle service. (we also had our car driven to the South Rim by a responsible person from Jacob's Lake Inn). So, all we had to worry about on our backs was food and water for the trip. Getting an early start (6am)allowed us to stay cool for couple of hours before the midday heat. We skipped both waterfalls, as we were determined not to be stuck in The Box in the worst heat of the day - forecast called for 105 F! Eazy breaze made it possible for us to move fast, and we were eating lunch at Phantom Ranch by 1PM. Despite the soaring temperatures, Bright Angel Creek stayed cool around 45 degrees, so that's were we spent most of the afternoon. Next day, early start again (even though we were the last campers to leave around 6 am), we made the easy ascend throught the Devil's Corkscrew to Indian Garden in about 3 hrs. The last leg is always the hardest - almost 3000 feet in elevation change on about 4 miles. As if the heat, the elevatation and the mileage wasn't enough, the "turist hikers" heading down are in your way on every step. However, we still made it out of the canyon by 2PM with plenty of time to admire the views on the way out.
