This is a combo loop made from 4 trails Hoeferlin (yellow), Macevoy (blue), Castle Point (white), and Skyline Connector (red/white)
We did this hike with 4 kids ranging from 2-6. This was not an easy hike, even if you are not with kids, there were some challenging points.
Start at the North Parking Lot. Head down the main path till it forks and veer left. Start following the yellow markers. There is one point midway it got confusing, there were yellow markers heading in 2 directions, take the markers going down. Follow the yellow trail till it meets the main path. Head on the main path till you hit the lake and turn right. Start following the blue markers.
Part way down you will see a stream coming out of the forest. We took a break here and cooled. We climbed the rocks up and followed the stream into the forest a bit, then headed back to the main path. Keep following the blue markers until you hit a fork. Take the road to the right with the 2 cement pillars. About 100 ft up is the white trail head. This part is uphill but it is not very long. About 10-15 minutes. At the end of the uphill will be the castle ruins. This is a cool spot to take some pics and hand out in the shade. Once your read to head down, on the other side of the ruins is a wide clear path, follow it down to the main path. Continue on the main path , but we on the look out for the white markers. You will pass a private house and a little after that the white markers are on your left. Follow the white markers all the way to the end. You will meet the main path again. Take a right and about 50-100 ft down veer left onto Skyline Connector (red/white) Follow that all the way back to the car.
Great Hike. Would definitely do it again
