This is a great place for overnight/longer trips. If staying overnight we recommend staying in the bivey campground in the park itself. This campground has a bouldering feature and is only 5 mins from the park entrance.
Get to the dome early as routes are scarce and it is a pretty popular place. All of the easier routes are on the backside of the boulder.
This is a great place for beginners. Don't work about rushing to get there as it isn't the most well-known location.
