Had a wonderful walk in the woods with the family today on this trail. It’s fairly well marked but several time we reviewed the map to make sure we were taking the right branch. The road getting to the trail was a bit soupy from the spring thaw, but the trail was fine. It’s a perfect spring or fall trail.

I can't believe this is in SE Mich. You show up to the park and suddenly there are steep hills everywhere. Love the constant elevation changes on the trails and the dense forest. Did the beach to campground hiking trail and then found the mountain biking trail and hiked that back to the beach (after checking out the scenic overlook on the bike path just past marker #4). This makes a great loop of 5 or 6 miles.

We arrived about 11:00 am for a walk around the lake under a clear blue sky. The temp was crisp when we arrived, with the muddy trails mostly frozen. There are about a half dozen stream crossings, most with bridges. We saw only one other person on the trail. The east and south sides of the lake are the best. The rest is mostly meadow trail. Saw geese, woodpeckers and heard other birds, including redwing blackbirds.

Well marked trails. Easy to get to. Mix of paved and non-paved paths. Closer to highway than expected. Mountain bike trails look fun though.

Beautiful sunny day, walk the 3.7 miles. 40% was muddy, use a walking stick, it will be more fun. I’m looking forward to doing it again soon.

Beautiful. A good variety of different terrain.

Great hike! It took about 3.5 hours (including breaks and photography). We walked the opposite direction (counter clockwise) so we wouldn’t be surprised by bikers (they go clockwise). Generally, this trail is very remote and serene. We’ll be back.

Trail still closed as of 3/17/18. Looked like it was due to mud as it seemed to be a well groomed trail. Bummed.

The Bloomer Unit is probably the best hike in Ortonville Rec Area. No hunting allowed and the deep woods trails are quiet and peaceful. Unbeatable in the fall!

The orange loop was great, very beautiful!

Excellent trail system right in my own backyard. Love the orange loop, especially. Layout is perfect for hiking, biking, and cross country skiing. The paddling is incredible here too.

These trails go around a landfill that has been filled in. The trail is well marked and there are a lot of options. It is not wilderness hiking as you can often see houses/roads and hear traffic, but the trees are very pretty and it was very leisurely, enjoyable hike.

Two friends and I did a shake-down hike here. Very beautiful but the trails were not marked very well. We got lost and had to navigate out. Trails are well-enough maintained but needs improvement with trail marking.

Try to get here during trillium season, there are huge patches throughout the woods. I try to get on this trail every May/June. It's a nice walk.

My husband and I went out today for some fresh air (March 11). The trails are still very muddy. We saw just one other person out on his mountain bike while we hiked on foot. It will be nicer when Spring arrives and dries out the mud. It was difficult to follow all the switchbacks on the map. We ended up doing a little over 2 miles. The entrance is in the fairgrounds. I'd rate this trail as easy, not moderate.

Still quite a bit of snow and mud on the trail, so wear decent trail shoes or boots. Wasn't terribly busy, but definitely saw a lot more people on the north half of the loop. Trail is not marked. Was easy to tell which direction to go by following tire tracks and footprints, but in a month or two when the trail is completely dry, I could see that being a bit of a pain.

Went on a snowy hike there in early March. Beautiful scenery and the lake is well worthy the trek.

This is a great trail, especially if you are new to mountain biking, like me.

Im a 29 yr Winter Back-Packer and after 6 years of dating my girlfriend she decided to give it a try and find out why for 29yrs I have enjoyed Hammocking in the deep freeze. although there are many beautiful places to go I chose the trails in Fort Custer to be her 1st winter trail Pack-In and camp-out. Here's why:. Its Easy, Its Beautiful, Its Quite, Its Close to Emergency's (If Needed it was 5 degrees at night) No body is hardly ever there (I may see a dog walker or 2 and the Trail I picked was only a 7 mile Loop with camp at the 5 mile mark giving only a 2 mile to hike back to truck if we needed it for emergency reasons(It was her 1st winter pack-in/camp-out and remember it was 5 degrees at night and 27 during day) If anyone is thinking about testing new gear,trying a 1st winter pack-in/camp-out or just enjoying a nice winter day hike Fort Custer has it. Trails are marked very well so if you can read a map or colored dots on trees then you will with no problems feeling safe and not get lost in Custer. These are All things a beginner should learn and look for during a winter Pack-in or hike. Enjoy! ( the water is turned off in campgrounds but all sites are open and Pit Toilets are available during winter season)

Cool place! Today was my first time here. The trails weren’t marked properly, making it hard to figure out where to go. I will be back, my dog and I enjoyed it ☺️

Great for a quick afternoon hike with great views. I was pleasantly surprised how dry the trails were given all the recent rain. I'll be here again.

Great trail. Loop 1-6 was 3.5 miles. Mostly snow covered, some areas were muddy.

Regardless of what this app says or anyone tells you while hiking in this area... you are not required to leash your dog in the State Game Area.

Great afternoon hike. Will do it again in the spring.

Drove over an hour to hit this spot to find the trails are closed until further notice due to weather.. even tho it’s nearly 50 degrees and sunny.. pretty irritated.

Out at PRSA today - Crooked Lake trail was in excellent condition. Essentially no mud, which surprised me given the rain last week. Many of the lakes and bogs still have some or a lot of ice on them. Saw 7 other hikers and one biker.

Nice area tucked away off busy 10 mile. Went for a 2 mile loop. Trail has plenty of very icy spots so be careful this time of year. Went at around noon on a nice Saturday and only ran into one hiker and a pair of bikers. Looking forward to going back to hike the entire trail

Nice single track, decent elevation and little traffic. Many loops to accumulate miles.

The park offers a lot of different route options, with paved trail, grass, and gravel surfaces. It's easy to customize your distance with a lot of connected loops.

Nice trail. Peaceful loop starting along the Chippewa River. One fairly strenuous hill.
