Mount Coolum was a good climb. It’s not as high as nearby Mount Ninderry, but it’s a more challenging climb because there’s more slippery rocks to negotiate.
I rode the bike down from Coolum Beach, chained it to a tree in the car park, and climbed from there.
There are spectacular views in all directions, but it’s not as panoramic as Emu Mountain. You need to move around the summit a bit to see in different directions.
Nevertheless, it’s quite high, and very close to the coast, so it’s worth having a look.
