The falls are located just to side of the road with a couple of different places to park. There's a $5 or $10 entrance/parking fee. A gre...

    Snowy Hike to Rattlesnake Ledge

    4.5
    4 mi / 1160 ft gain
    The trail to Rattlesnake Ledge is one of the busiest in Washington. Usually, a Saturday or Sunday is a no go for a lot of avid hikers due to the crowds.

I usually use it as a starter hike to kick start the season and highly recommend you get an early start on this one as the further...
