used to be right up on the water here, which became pretty nice in the summer months. since the lowering levels id recommend heading somewhere toward the Mohave line as you will not have to commute as far to lake drop ins. otherwise, mountain biking has picked up in this area with easy access to a wide variety of both single track and downhill.
Great primitive campground on the Nevada side of Telephone cove. There's a boat launch, vault toilets and that's it. It's free so it fills up fast on weekends with campers and day use water enthusiasts.
