On back-to-back days, we paddled the Seymour Arm of Shuswap Lake and  the southern end of Adams Lake.   The contrast was amazing.  

Although the Seymour Arm is a remote and scenic spot, it was inundated with dozens of houseboats, jet skis, powerboats, noise, and a collective disregard for others.   The area is probably very quiet in the off-season, but we can't recommend it in the summer.  

On the other hand, we found Adams Lake to be remote, quiet, and relatively deserted.   No houseboats, jet skis, or ski boats.   Every time we travel to the shore of Adams Lake, we find clear water, wildlife, and a quiet wilderness environment.   The lake is long with a few access routes off Holdings Road.   We drove north to the lake, then past the mill at the south end to Adams Lake, then a few kilometers north to Adams Lake Provincial Park (Bush Creek).   We parked at the campsite and used the boat launch, paddling north up the shoreline toward Agate Bay.   The water in the lake is high so the beaches are covered, but there are few roads, few homes, and lots of scenery.   On a previous trip we had found broad, pristine beaches.   We will return to Adams Lake many times.   Shooting video from a kayak is a challenge, but we posted some footage to give readers/viewers a sense of the sights and sounds:
