There's an unactivated FTF geocoin trackable for the first to find.
If you have sturdy shoes, plenty of food and water, and maybe some hiking poles, head up this trail. It's called Paddy Go Easy to remind you to take it easy -- the uphill climb will provide you with plenty of challenges, but as you get higher, also many rewarding views. There is one more cache (in rough shape when I just visited) all the way at the top -- I had 2 more to place along the way, but away from the road is part of the Alpine Lakes Wilderness. No new caches are allowed in wilderness areas, so be warned if you are thinking of hiding a cache out here!
Driving directions: Get yourself to Roslyn, WA. Take 1st street through Roslyn, then keep going on Salmon La Sac, which eventually turns to dirt and becomes Cle Elum Valley Road also known as NF 4330. The parking area for Paddy Go Easy is roughly 12 miles after the road turns to dirt. There is a wooden sign at the parking area that says Paddy Go Easy. You will have to ford the Scatter Creek Crossing -- dry in late summer, but this can be an adventure in the Spring -- you may well want a AWD higher clearance vehicle to do so in May. You should really be sporting a Northwest Forest Pass in your car which is required in this area. Get one before you leave at the Cle Elum Ranger District: 803 W 2nd St, Cle Elum, WA 98922
