Hiking

Frozen in the morning, snow packed last 3 miles up, and muddy on lower sections on the return. Snowshoes were useful the upper 3 miles. Walked back on the road from where the trail crosses the road about a mile down from Affleck Park because of the mud.

HikingGreat!

They have redone the trail to make it more fun for mountain biking and to provide more shade. For us on foot, it made it much dustier since it is not hard packed like before. I assume the trail we’ve hiked in the past is merely near where the pioneers and Pony Express came through; I guess the same can be said for the newer, meandering trail. We parked at the trailhead about 2 miles up the canyon from the Little Dell Reservoir and walked to it. We went on 9/25, and the peak fall colors had passed (in addition to this year’s foliage just not being as bright). We always enjoy this trail since it is mostly level and the reservoir is a nice destination.

Nice trail for an easy mountIn bike ride. We walked the trail. Easy and almost flat. It was quiet and saw some fall color. I think we missed peak time.

my sister and I did the full trail from little Dell to Mormon Flat and back. finding the trailhead took a little searching. you need to go down to the reservoir and then pick it up on the north. there are trail markers periodically. at Mormon Flat you have to side step a narrow muddy edge of a stream to get out to the parking lot and toilet. good dirt trail with a few rocky sections. there were a lot of mountain bikers on the trail.

Only went 1 Mile on the trail (2 miles total). Bouts of shade throughout, but also pretty sunny. Flat for the mile we did. Wide enough at the start for 2+ across and then single file. Didn't need bug spray.

Hiking

Started this hike near the Affleck Park Campground and went up to the Big Mountain summit and back for a quick morning excursion, about 5.5 miles roundtrip, 3 hours total. Delightful verdant journey and mostly shade since we started before 9 am. The narrow packed dirt trail was damp for rains of the past few days and very easy walking with only a few sections of steep grade. Mountain bikers going up and down so, yes, beware. Most of them had bells or announced themselves but not all, so be vigilant! This section is recommended as an easy hike.

Great trail. Shade and sun. Lots of beautiful sunflowers along the way. The guard at the entry gate of Little Dell parking area had no idea where this trail was. Just below the parking lot to the left, follow a short path. The right side will go down to reservoir and the left, upper most trail is the actual Pioneer Trail. Lots of mountain bikers so hikers beware. Not too challenging of a hike. Once you get to end of the first portion of trail, you’ll cross road and continue. This part was very muddy. Lots of twist and turns so watch out for the bikers.

If you’re looking for a great way to see the fall colors and have a gentle hike, go up about 2 miles past Little Dell Reservoir. There is a bathroom and trailhead for the Mormon Pioneer/Pony Express Trail. It slopes ever so slightly downward toward the reservoir. Round trip the hike is about 3.8 miles. We did this on 9/30 in the afternoon and had the trail to ourselves. Gorgeous colors probably around for another week or possibly two.

Really pretty fall colors right now. It was raining today at lower elevations and snowing higher up, but just a thin layer sticking, and nothing on the trail.

Enjoyed this trail. Pretty shaded. We did about 2.5 miles and then turned around and headed back. Drive in through the Ranch with cows and horses on the dirt road was a highlight for the kids.

I enjoyed the hike. Only did 11 miles r/t, but the views and scenery were awesome. Mostly cyclists, saw only one other hiker. Start at the trailhead to the left side of Hwy 65 after passing the parking lot of Little Dell Reservoir. Discovered Affleck, a nice campsite.

Road closure thwarted my plan to try lookout peak from Affleck park so I skied the Mormon Pioneer trail up and after encountering a group of dorks shooting guns from the road decided to call it a day.

I did the entire 18+ mile round-trip today from the trailhead close to the reservoir to Mormon Flats. The weather was great, a little cool early but that's better than too hot. I saw several deer and three of them bounded across the trail about 20 feet in front of me. If one of those animals hits you you're in trouble. The trail is very rocky but well marked and well traveled, there is no way you'll get lost. As for Alltrail's directions to the trailhead, you're on your own. It costs to park at the reservoir trailhead at the day-use area, but Alltrail doesn't mention that or where the day-use area for the reservoir is located or how to get to it. If all else fails just drive Highway 65 and look for the parking lot and fee booth above the reservoir. If you want a slightly shorter hike, drive on and look for trailhead markers along the highway. Eventually you'll see one for the Mormon Pioneer trail. The elevation gain of 3000 feet is well distributed over the length of the trail so it's manageable. I went all the way to Mormon Flats and tried to imagine what it was like to have been camped there in 1847. Why are there no markers for Fort Wells? As for bikers, several passed me in either direction and only one yielded to me. The rest slowed but made it plain by their actions that I was going to get hit if I didn't get out of the way. If you're a biker, please obey the rules.

We started at the trail head up top by cell towers and hiked down to Mormon Flats. It was about 4 1/2 miles, nice gentle downhill hike. We left a car at the bottom. Beautiful hike with fall colors starting to come out. Fun that this was a Pony Express route, trail of the Donner Party, and the first Mormon Pioneers. It was a lovely hike!

For the love of all that is holy, follow the TRAIL markers, NOT the map that All Trails gives you! This was my first time using the app as my map and guide. When I came to the first fork in the road starting from Dell Reservoir, the All Trails map tells you to go right on the larger road while there is a small trail marker indicating the left trail. I’ll give you a hint - don’t go right. If the trail starts to get really narrow and somewhat overgrown, if you’ve crossed a bridge right at the beginning, you’re on the wrong trail. I met a lost hiker up there, too. Anyways, once I finally figured it out and biked back to the beginning, it was much better! It’s a steady climb up from the reservoir, but the ride down is super fun! I didn’t see any hikers, just bikers. I went up past the road and bathroom, continued on the other side up until a little ways past the campground. The road is close and you can always hear cars, but still fun.

Beautiful trail...lots of wildflowers but apparently there are some who don't care it's a watershed area. Crossed paths with a couple with TWO dogs. Will be back to this trail. Awesome!
