A good training ride if you need to get in and out fast. Steep and grueling at times it can really test your limits.
Rattlesnake Mountain is a long ridge overlooking the South Fork Snoqualmie River Valley, Interstate 90, North Ben, and the Cascade Mountains on the east and the Issaquah Alps and Puget Sound basin on the west. Although the hillsides have been stripped of their forests and the ridge crest dotted with telephone and radio relay towers, the riding is outstanding. The loop climbs over the summit ridge of Rattlesnake Mountain then descends along the Raging River drainage. The ride is almost entirely on logging roads, some in excellent condition, some steep and rough. The road is gated at the base so the entire ride may be vehicle-free when loggers aren't working the area.
How to get there:
Drive Interstate 90 east from Issaquah for 8 miles to Exit 25. Turn south on Highway 18 for about a quarter of a mile, then take the first left on SE 104th Street. Go straight for 200 feet then park in the large open area at the right-hand side of the road.
If you're looking for awesome scenery this is the place!
