Three Mile Beach is really two beaches on one peninsula off Naramata Road: a fine-sand swimming beach beneath sandy bluffs, and a rockier boating beach with day moorage for boats. The dog rule follows the split: dogs may run off leash on the South (boating) beach but are not allowed on the swimming beach. It is worth knowing that Visit Penticton notes the area is well known as a nudist spot. The City lists no facilities here.
