Great place to trek. I was there with my wife and kid couple of weeks back on a beautiful semi-cloudy day. I think its the best time to trek these peaks. My wife and 4year old girl were trekking along with me. Had to carry my little one couple of times but other wise she enjoyed walking and running along. Great views from above.
One word of advice, never try to touch those tiny cacti. I tried touching a nodule of teddy bear cholla which was lying on the ground.. and the next thing I knew was my four fingers got tangled with the thorns deep in my fingers. Was able to get them out only after 10 mins !
Overall great experience and adventure for me and family :)
