The Brown River has a series of falls that are called the Medicine Bowl Falls. They are located off Forbidden Plateau Road, just outside the Comox Valley. These are awesome falls and easy to get to.
Three waterfalls were born from Browns River. that were carved out by the force of nature and rushing currents. The Medicine Bowls Trail is a great hike for novice walkers, offering spectacular views after a short 2 km walk on a dirt road at the end of Forbidden Plateau Road west of Courtenay, BC.
I have driven my car into this spot, but I would not recommend you use this road unless you have a 4×4 vehicle. The road can be quite rough. At the end of the road is a large turnaround area where you will see a memorial to 2 young swimmers who lost their lives here. This is a very popular swimming hole, but dangerous; one should be careful as the rocks can be very slippery.

At the end of the road, you will see a rock cairn with info about two young lads who drowned there. There is a trail heading down. You walk along this trail for about 1/2 km, and then you will reach the falls and canyon. Please be careful here, like I stated already, the rocks can be very slippery, and you could easily slip, fall and hurt yourself or worse.
In the summer, the river water drops, and you are left with these fabulous “bowls” of water, just like a hot tub! The rock is sandstone, so it gets really hot. These bowls are awesome to see, and when the water is running high in the winter, it is incredible to see. After a big winter rain, the water can be quite high, and it thunders down these falls with a roar.
Update: It is best to park in the pull-out at the junction of the Forbidden Plateau Rd and Brown River Falls Rd and walk in from there. The road has become pretty rough.
