Best overall pick
Lake Siskiyou Beach & Splash Zone
Near Mount Shasta City • Family-Friendly Lakeside Beach • Best Mix Of Swimming, Views, And Amenities
A managed sandy beach with big mountain views, roped-off swimming, and an easygoing, kid-friendly vibe.
For many locals, Lake Siskiyou is the go-to when the thermometer spikes, thanks to its soft sand, mellow water, and postcard views of Mount Shasta across the lake. The designated beach area offers roped swim zones, seasonal water toys for kids, and nearby concessions, so you can stay all afternoon without packing the entire kitchen. It works just as well for a quick post-hike dip as it does for a full-day lakeside hangout.
02
Best wild escape
Medicine Lake Recreation Area Beach
Medicine Lake Highlands • High-Elevation Volcanic Lake • Best For Quiet, Uncrowded Swims
A cool, clear mountain lake with simple shoreline beaches and a backcountry feel far from highway noise.
Set in an ancient volcanic caldera, Medicine Lake feels worlds away from the bustle of I-5 and Highway 97. The small day-use beach areas are rustic—think pumicey sand, picnic tables, and cold, clear water that wakes you up fast—but that minimalist setup is part of the charm. It is a great choice if you want to pair swimming with camping, paddling, or exploring the nearby lava flows and forest roads.
03
Best combo with a waterfall visit
Lake Britton at McArthur-Burney Falls Memorial State Park
Mcarthur–Burney Falls Area • Reservoir Beach With Classic Park Feel • Best For Pairing Swimming With Sightseeing
A laid-back lakeside beach just up the road from Burney Falls, with gentle water and an easy park setup.
After you have walked the loop to see Burney Falls, Lake Britton is where you cool down and spread out. The beach area has the simple comforts you want in summer—picnic spots, mellow swimming, and space for kids to dig in the sand or splash near shore. Expect warmer water than the high-elevation lakes closer to Tennant, plus the option to rent small boats in season if you want to explore beyond the swimming zone.
04
Best big-lake feel
Bailey Cove Beach, Shasta Lake
Shasta Lake, North Of Redding • Sheltered Cove On A Major Reservoir • Best For A Full-Day Lake Outing
A protected cove on Shasta Lake with a small beach, nearby boat ramps, and that classic big-reservoir scenery.
Bailey Cove puts you right on the edge of Shasta Lake without dropping you into the chaos of the busiest marinas. The compact beach and picnic area work well for families or small groups who want a simple base for swimming, paddling, or meeting up with friends who are out on a boat. Water levels on Shasta fluctuate, but when they are decent this cove offers an appealing mix of sun, shade, and easy access to the wider lake.
05
Closest local shoreline
Lake Shastina Shoreline Beach
Near Weed And Lake Shastina Community • Low-Key Neighborhood Lakefront • Best For A Quick, Close-To-Home Swim
A modest stretch of shoreline on Lake Shastina that locals use for quick dips, paddling, and sunset watching.
When you do not have time to drive all the way to Mount Shasta or Shasta Lake, Lake Shastina is often the most practical choice from Tennant. Depending on water levels, you will find small pockets of beachy shoreline where you can wade in, launch a kayak, or relax with a camp chair near the water. It is not a polished resort-style beach, but for a close, easy swim with mountain views, it more than does the job.
