We got this recommendation from our host at Glenella Guest House. From the Blackheath community pool, follow Popes Glen Walk through the preserve (morning walk will be rewarded with prime bird watching) to Pulpit Rock Walk and Govett's Leap. We saw few people on the trail, and very few at Govett's Leap itself. And the views are just as nice as Three Sisters. We finished the nearly 9km walk on Breaside Walk headed back to town. Well kept secret in the Blue Mtns!
