Mount Leinster East Top is an uninspiring rise, just under 2k east of the main top. It is often confused with Black Rock Mountain, which is a further 2k east and is more defined.

There are a number of ways to reach the top. The most obvious is to use the service road leading to Mount Leinster itself before heading east over the bog to the East Top. The road begins at a viewing point at a height of 400m on the South Leinster Way at S81645 54640 A, where there is parking. This route will take in the order of 2.5 hours.

A more interesting ascent starts at Ballycrystal S860 506 B, heading north to Black Rock (599m; not a MV listed hill), then west over Mount Leinster East Top and onto the main top. A return trip is c. 4 hours, but probably an hour less if you forego the main top. Some parking is also available at S843 516 C which provides a short, but steep ascent directly to the summit or an alternative point for a second car.

The views from the top of Back Rock Mountain are almost as good as those from Mt Leinster itself. Makes an ideal stop on a circuit of Ballycrystal. Picture shows the summit cairn and the view towards Mt Leinster itself. Linkback: https://mountainviews.ie/summit/184/comment/879/

Looking at Mount Leinster East Top from Mt. Leinster with Black Rock Mountain in the background as per the photo. Parts of this short route were particularly damp and boggy in contrast with most of the surrounding mountains. Linkback: https://mountainviews.ie/summit/184/comment/1350/
