Had a 4 day break here in our camper trailer. If your after lawned completely flat bays, don't stop at coalmine, but if your after a nice leafy park, with lots of trees around for shade, that bring in the magpies, kookaburras and kangaroos this is the spot. Ablutions are adequate, several clean bbqs around, great playroom/tv room with ping pong table, kids playground that was very popular. Fire pits in every other bay, with wood available in the on site shop.
Walpole is a 2-3 km walk away through a scenic walking trail. We walked the Knoll scenic drive, about 4 km trip, which starts and finishes just outside the park.
Weekend was fairly busy in the park as it was around Australia Day, but was very quiet midweek.
Had a look at the knew glamping tents. Very nicely set up, family tent has 4 bunks, queen bed , lovely bathroom and kitchenette. Very roomy.
