One of the more well known wine regions in the country. Famous for Semillon and Shiraz. Due to the distance between wineries it is not the best place for biking between wineries but it is possible around Pokolbin. The hop on hop off tour or guided tours are probably a better option. Many wineries are charging to sample wines.
This road should be OK for 2wd if the weather is dry. Fairly easy 1 1/2 hour track walking track through beautiful sub alpine forests. Lots of lookouts. The waterfalls are spectacular after rains. You can also walk the Gloucester Tops circuit here which takes about 4 hours and is one of the best walks around.
