The summit has great views of the Confederate Salish-Kootenai Tribes land, the Flathead River, three alpine lakes, the Mission Mountains and the Ninemile Valley.  A Flathead Reservation Use Permit is required. 

Vermilion Peak is accessed via a moderately climbing trail in the southern Cabinet Mountains.  It also makes an easy SOTA double when teamed up with Mount Headley, W7M/LO-018.  The summit has fine views of nearby summits and distant peaks, like the Cabinet Mountains Wilderness Area.

Summary:

Gifford Peak is a forested summit above Blue Lake in the Indian Heaven Wilderness. This area is a popular destination for day hikers and backpackers, directly on the Pacific Crest Trail, so be prepared to meet crowds any day with good weather. The lake can be approached from either Falls Creek Horse Camp or the Thomas Lake Trailhead. Once there, take Thomas Lake Trail to the northwest corner of the lake, and proceed up the ridge off-trail. The ridge is pronounced and easy to follow to the true summit.

Approach: Rough gravel road in from Hyak.  Little parking and congested driving at hairpin curve ~1.7 miles before  the trail head.  Just past the hairpin curve the road is extremely steep, rocky and potholed, to the point only vehicles with good clearance can get through. (I have an Outlander PHEV that did fine going up, and scraped on one rock coming down.)  Once at the trail head it was busy, but easy to find an open parking spot on a Sunday afternoon.  

TL;DR version - A nice four pointer and a good place to do a leisurely activation. Enough of a hike to feel like the one worked for the summit. Good APRS coverage, okay ATT data coverage. QRM on small portions of the CW frequencies (40/30/20M). Get there early or risk not finding a place to park and don't forget your WA Discover Pass.

Big Mountain is part of Whitefish Ski Area and in the summer you can take the chairlift to the top ($20) and hike, ride bikes and activate Big Mountain.  The communication towers that sit atop the summit are easy to see from the top of the chairlift and it's only a short quarter mile walk up the graded road to the top.

This summit is a progressively more difficult climb as you ascend. The activation is challenging but rewarding. The route I took starts with an easy well trafficked trail, but the second part of the ascent has no trail and involves navigating through the Angell Basin which consists of areas of large granite boulders.
