Maple Mountain is above Mapleton and Spanish Fork, I grew up in Mapleton and hiked that mountain more times that I could count or remember. It’s a gorgeous hike but a longer one, there’s a nice pond we call Maple Lake when you’re most of the way up and it’s a great place to stop for a while before finishing.
The trail starts at the top of Whiting Campground, a quarter-mile after that you cross the creek to take trail 007 and can’t miss it from there.
I’ve had the hike take 12 hours up and back many times including time to play in the lake and catch salamanders but when hurrying and when in Shape I’ve gone up in 2 hours and come back down about that quick.
There’s plenty of wildlife and scenery and amazing views of the valley from the saddle (after the lake and before the top.)
