Kepros Mountain Day Hike - Grand Slam Weekend

Sat, May 2 · 7:30 AM MDT

Albertsons 6560 S. Federal WAY Boise, Idaho, 6560 S Federal Way, Boise, ID, US

Join in the first leg of the Idaho Hikers and Backpackers Grand Slam Weekend on Kepros Mountain!

If there is one hike to do this weekend, Kepros is the one. Kepros is a moderate hike of 9.5 miles, with 1978 ft of elevation gain. It's never very steep (except for the steep one part you can see from the parking area...trust me, it's not all like that). From the summit you can look down on Lucky Peak (the reservoir) from far above.

If you are feeling strong after the Kepros hike, you are welcome to continue on to summit Lucky Peak as well.

Note: you do not need to sign up for this event if you are already signed up for the either the Saturday or Full Weekend events. We just want those who can only join for one hike know they are welcome.

We will meet near the Subway in the Albertson's parking lot on Federal Way & Hwy 21 so we can carpool to the trailhead. Parking is good, but somewhat limited. This will be the meeting point for all the Grand Slammers on Saturday ... the Kepros-only group, the all-day-Saturday group and those of us attempting the complete Grand Slam. It should be a great time.

Mt. Heinen Day Hike - Grand Slam Weekend

Sun, May 3 · 8:00 AM MDT

Albertsons 6560 S. Federal WAY Boise, Idaho, 6560 S Federal Way, Boise, ID, US

Join in the third leg of the Idaho Hikers and Backpackers Grand Slam Weekend on Mt Heinen.

Day 2 of Grand Slam weekend kicks off with Mt. Heinen. Join the group for a challenging hike of 9.6 miles and 3717 feet of elevation gain. Since this is an out-and-back hike, you will see most of that gain in the first half of the hike, so it may be the toughest 4.6 miles of the year (so far). It won't be an easy hike, but if you arrive fresh you might be able to leave Scottie in the dust.

If you are still feeling strong after summiting Heinen, stick around for Cervidae. It's right down the road anyway. And it's short, right? ;)

Note: you do not need to sign up for this event if you are already signed up for the either the Saturday or Full Weekend events. We just want those who can only join for one hike know they are welcome.

We will meet at the trailhead for Mt. Heinen along the shore of Lucky Peak Reservoir. Some of the group will already be camping in the area, so please give yourself plenty of time to make your way up the winding dirt road to the trailhead.

Note: The group members are camping near the trailhead at the Irish Point dispersed camping area. Keep your eyes open for the group among the campers if you arrive early, but please meet at the trailhead for the hike.
