Having bagged Knockullane, you may be tempted to approach the east top directly. Don't. A mere 1.8km away, yet it is a nightmare of swampy ground, hidden barbed wire, the remnants of clear fell which must be clambered over and various other obstacles. My suggestion is to head back to your car from Knockullane, drive to W23055 81392 B, an follow the forest trail to W236 801 E, where a lesser trail leads directly up the hill and will take you virtually to the top, which is a heathery hump marked only by a stick. It may add 4km to your walk, but it's worth it to avoid the misery of the direct approach. Linkback: https://mountainviews.ie/summit/789/comment/23462/
