Even though Roundtop Peak does not have a great deal of prominence, it's location away from the closely-packed ridge systems of the Pine Ridge, makes it visible for many miles away.
It is an easy peak to reach the summit of, and visitors will be amazed at the great views of the badlands of Toadstool Park and Cedar Canyon to the north, and the Pine Ridge forests and peaks to the west and south.
To get to the Roundtop access point, go north from Crawford, Nebraska on Highway 2 & 71. The Toadstool Road turnoff is just over 4 miles north, and is well-marked. It goes straight west for 2 miles then sharply turns north-northwest. Six miles from the turn is the turnoff road for Hudson-Meng, and is shown on many maps as Sand Creek Road. That road is well-maintained and well-marked.
Just past the junction with Milo Road, you will see on the right an old 2-track road marked 918. Follow that course for .5-mile and you will be in the saddle between Roundtop Peak (east) and Pine Butte (west). That's a good place to park and do an easy hike up Roundtop (Pine Butte next, if you are so inclined)
