Mount Headley is easily accessed via a moderately climbing trail in the southern Cabinet Mountains. It also makes an easy SOTA double when teamed up with Vermilion Peak, W7M/LO-056. The summit is the tallest in the area and has fine views of nearby summits, lakes and distant peaks. Be sure to stop and view Graves Creek Falls w
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.
Follow any road map to Soda Mt. Rd or Hobart Bluff TH off of Hwy 66. You will follow the gravel road down past Hobart Bluff Trailhead, there is a parking area and restroom here. Go on past the trailhead aways until you reach the gated driveway for Soda Mountain on the right. It is a 1.5 mile walk up to the summit using the road. Minimal parking area as you will be in wilderness and there is very few pullouts to park in.
Henline is a relatively low traffic hiking trail in the Opal Creek Wilderness. It boasts rhododendrons, a mostly-well-maintained trail, and reasonably consistent gains. The hike is entirely on public right of way, and can be accessed via North Fork Santiam Road and NFDR 2207 from Hwy 22 out of Salem. Turn left on North Fork Santiam Road about 22 miles from I-5, then drive straight. Eventually this road turns to a moderate gravel road, followed by a fork between 2207 and 2209. Take the left fork and head uphill a ways. You'll pass the more popular Henline Falls Trailhead.
Flattop Mountain is a drive-up for those with capable high clearance vehicles. And maybe for those ready to buy new tires - which was required of us - as the road was steep with sharp rocks.
Here's a nice summit with a trail to the top, about 5 miles RT and more elevation gain that you might have wanted at 1800 feet - but know that it's worth it. A bit obscure perhaps outside of huckleberry season, you might not see many folks at other times. The views of Mt. Adams are fabulous.
