Manitoga - Sugarloaf Hill - Castle Rock - Glenclyffe - Arden Point Loop:  13.5 miles
Manitoga - Sugarloaf Hill - Castle Rock Loop:  10 miles
Manitoga - Sugarloaf Hill on Osborn Loop:  8 miles

Although this is a pleasant hike in the summer many of the views are obstructed by foliage.  Go when the leaves are down for the best views.
The hike starts at Manitoga.
Dragon Rock
Trail starts as white/blue/red.

Castle Rock
Exit the blue/red Castle Rock Trail at the Castle Rock pillar and cross over Route 9D.
Sign along Route 9D
Turn right and walk north along Route 9D briefly then turn left before the Garrison Institute sign.
The beginning of the Marcia's Mile Trail is behind the map.  You have to duck under the beautiful, large evergreen tree to find the marker.  If you pass the 10 mph speed limit sign, you just missed that tree.
Marcia's Mile marker on large tree behind trail map.
This sign is a little farther along the trail.
When turning right at this sign heading towards Arden Point, watch a few steps along for stone steps leaving to the left.  Make note of that trail as the turn is not marked and this will be the trail to take after returning from Arden Point.
At the end of Marcia's Mile turn left and cross the bridge over the railroad tracks to Ardens Point.

Historic Overlook (obstructed by foliage) of Benedict Arnold's escape point at the Hudson River.
The trail follows part of Benedict Arnold's historic escape route.
The red-blazed Glenclyffe Loop Trail comes out at a mowed lawn.  Turn right and head towards Route 9D then turn left and and follow Route 9D a short distance before crossing over at the Castle Rock and Wing and Wing pillars.  Follow the signs for the parking lot as you proceed along the blue-blazed trail.  Continue following the blue markers through a meadow.
The blue-blazed trail crosses through meadows with lots of birds and butterflies with better views of the castle.

Because the field was very overgrown blue markers fizzled out but keeping straight through the meadow, go up small incline into the woods up on an umarked woods road with the state property boundary signs to the left.  Turn right and follow this unmarked road through the woods straight to the red trail at the gazebo.

Continue on the red-blazed Sugarloaf Trail back to the intersection with the blue-blazed Osborn Loop Trail, then continue straight on the blue-blazed trail towards another gazebo.
The blue-blazed Osborn Loop Trail ends at the white-blazed Appalachian Trail.  Turn right and follow the AT until you reach the beginning of the Osborn Loop which will bring you back to Manitoga.

  1. Thank you very much for this very helpful guide. I've hiked the blue and red trail from the Osborn Loop but I never knew one can take the AT trail to connect to the blue Osborn trail from Manitoga. Now I can take the Metro-North train to the limited stop at Manitou to visit Manitoga, then take the Osborn trail to Arden Point. Then on to the local train station in Garrison.

    1. You are very welcome! So glad it is useful for you.
