The Big Four Mountain and Ice Caves in the Mt. Baker-Snoqualmie National Forest are off the Mountain Loop Highway
outside the town of Verlot (where you must pick up a trailhead parking pass for $5 at the Verlot Public Service Center). The ice caves are a nice short hike with the help of the new aluminum bridge that gets you across the river. As of June 27, 2009 the new bridge opened(the old bridge was washed out in 2006). Questions? Call the Darrington Ranger District 360-436-1155.
