Horse riding AND Mountain Biking are BANNED when snow is present. (They open the park up to Cross country skiing from the Hobart Parking area... ski rental and all)
Pets must be on leashes.
Let's begin with what Chapin is NOT. It is NOT singletrack. It is NOT an epic ride. It is not somewhere where you can expect to ride without seeing someone. Chapin is a great opportunity to ride when the singletrack trails are too wet. When you don't have time to drive 30 minutes to Atchinson, or 1+ hour to any of the other CAMBA maintained singletrack such as Westbranch state park or Vultures knob.
Chapin is a great place to get out on your mountain bike where you don't have to dodge cars, and are still in the woods. Chapin is a GREAT place to take your young kids to get them comfortable riding on something other than cement.
Chapin is a great way to get in a 45-55 minute ride when the real singletrack is too wet to ride. There is perhaps 1/2 mile of rocks that are fun to bounce down on "lucky stone loop" but other than that, it is simply a wide crushed gravel trail through the woods.... that is friendly to Mountain Bikers.
Please pay attention to where you are going. I used to live across the street from the park and would regularly get people from the 306 side trying to find their car on the Hobart road side. The "Stacked loop" design of the upper section confuses people. Pay attention to what trail you are on and maybe what direction is North....
I like to park at the Hobart Road side take the trails across to the 306 parking side, that way you are rewarded with plenty of steady climbs from both directions and they seem to be spaced nicer than if you go the other way...
There are picnic areas, restrooms and even water fountains near some of the parking areas. Chapin is a very popular park, even in the worst of weather I regularly see several hikers in the area.
Please keep in mind that this is a shared use trail. You WILL see pedestrians, people with kids, and people on horseback. Remember how to pass someone on a horse... stop, and ask them what you can do to go past, and do what they ask. We need to keep these trail users on our side, or at least not make enemies.
