My old neighbor from Renton has 40 acres up the Chilwist Rd. and I usually go up and ride every year. You can get to "Loup Loup several ways:
Go up Chiliwist Rd, take a rt. at the corrals and go to "Lander Road". There is really no place to unload and park on Lander Rd, so if there is enough snow, park near the cattle guard and ride up Lander Rd. In about 3/4 of a mile, you will come to the end of private property and will be on State land if you go straight ahead over a cattle guard there.....In a few miles, Landers will come to a "T" intersecton, go left (west, uphill).....Keep going past the Woody Mt. rd. and continue for another mile or two until you are heading kinda south. When the trail you are on kinda merges via a "Y", make a hard right and head north on the "Y"....You will be on some cross country skill trails and this will merger with the "South Summit Road"....This will take you to Highway 20 and a snow park. Near the snowpark signs on your right is a trail heading east.....Take it thru the trees and it will take you to a safe and easy location to cross Hwy 20.....From there, you can pass the Loup Loup ski area, make a right and ride to Conconully.
OR - Go up Chiliwist and take a left at the Corrals. In about a mile, that road ends at a "T".....Unload, take a right and head west. This will also take you up to the South Summit road, where you would take a right and head north. Take a map or GPS, there is one tricky turn you don't want to mess up on.
Current conditions - They had a good dump, it rained and was solid ice as of a week ago........Good luck...
