Thanks, Tretta. Very helpful. Anybody else have any thoughts on the heat and water situation being manageable in the lower sections from the Mexican Border for hiking the first part of May?
As stated, May is not the best time to be in the desert trekking, especially when the trail offers such a variety of experiences that are more suited for the heat. IF you do decide to try it, umbrella and lots of water as mentioned. Electrolytes for sure, but also salt - just plenty of salt each day so that you don't experience hyponatremia. Also, you'll be hiking early - on the trail by 4-5am. Sit out the heat of the day by creating shade with umbrella, mylar blanket - what ever you have, then hike in the evening til dark. Passage 1 will start out hot but then you'll quickly get up in the sky island. 2 and 3 will be pretty warm as will be both ends of 4 - you'll get some elevation in the middle. 5, 6, 7 offer great views but little shade. Passages 6 and 7 you will be leaving the grasslands and entering cactus and desert flora. As far as shuttle in that area, Ken's shuttle service, listed in Resources on the ATA site, may be able to help. Final thought - May can be fickled. Some years the heat doesn't come til mid-May. Other years - WHEW! As always, Mother Nature is unpredictable.
