We rode Blue Grouse then took a right on Mule Deer some nice singletrack and kinda technical. You'll eventually get to some campsites just follow the signs for Mule Deer, from here go up the valley..soo nice with a little climb..then descend down a loose rocky douletrack. Keep climbing to the Panorama Point its pretty cool up there, I guess there are some views up here..but the day we rode (5-29-05) it rained off and on all day..so we'll be back. No real long downhills but it is alot of fun getting back to your car if you parked at Kirley Pond. $5 a car is well worth it..hardly anyone there!!
