The Grand Slam Peaks

The Grand Slam Peaks are 4 peaks near Boise that I have used for Spring Training for many years. These peaks generally melt out early and offer an enjoyable range of hiking experiences for people anxious to get out into the mountains.

I generally climb the peaks starting with [the lowest] Cervidae Peak because it always melts out first. It is often snow-free by mid-February. I then tackle Kepros Mountain. Kepros offers ridge walking with great views. It is a 10-mile up-and-down hike, which really will stretch your legs. As a bonus, you can climb Peak 5380 that lies midway between the trailhead and the summit of Kepros Mountain.

Shaw Mountain/Lucky Peak is #3 on the list. My favorite route for this peak is from ID-21 where the Highland Valley Road leaves the highway. I like to mountain bike this route because it makes the descent pure joy. There is no better place to view Boise than from the top of this peak.

Finally, Mount Heinen is the real test for your conditioning program. If you can climb Heinen and feel strong doing it, you are probably ready to tackle higher peaks. If you take the standard route, you will find that it’s a real challenge and is an extremely enjoyable route. Scroll down the page for links to “Extra Innings Peaks” for additional Spring climbing ideas.

Here are links to 2 other takes on the Grand Slam Peaks. Both are good reads:

Home Runs—Speed Records!

  • Traditional Vehicle Shuttle Between Peaks:  P.A. Campbell climbed all 4 Grand Slam Peaks on Sunday, June 10, 2018. Campbell started with Mount Heinen at 5:20AM followed by Cervidae, Lucky Peak and finishing with Kepros. Campbell’s total time, including driving, was 16 hours and 25 minutes. He used the following routes: Mount Heinen (Irish Creek Standard Route); Cervidae Peak (Southeast Ridge Standard Route); Lucky Peak (Canyon Springs/Homestead Route staying on the road, no short cuts) and; Kepros Mountain (Standard Route using Bypasses #2 and #3).
  • Completely Self-Propelled: Erik Pohlmann climbed all 4 peaks in a 24-hour period. Read about Erik Pohlmann’s epic adventure by clicking on this sentence. In case you want to take a run at Erik’s record, you have to beat a time of 20 hours and 13 minutes while ascending 15,500 feet and covering 93 miles–all self-propelled. Good luck with that.
