Best overall pick
Medicine Lake Recreation Area Beach
Medicine Lake Highlands • High-Country Family Beach • Local Favorite Day Trip
A sheltered swim beach on a clear volcanic lake, ringed by pines and classic picnic spots.
Set in the Medicine Lake Highlands, this small sand-and-gravel beach feels like a classic mountain swimming hole with room for kids to splash and adults to stretch out a camp chair. The day-use area sits close to campgrounds and boat launches, so it is easy to mix a lazy afternoon on the sand with paddling or a short hike through the surrounding forest. Afternoons can get breezy, so many locals aim for late morning when the water is glassy and the shoreline is quietest.

Best classic lake day
Lake Britton Beach at McArthur-Burney Falls Memorial State Park
Near Burney • Forest-Framed Swim Beach • Great For Families
A broad, managed swim beach on Lake Britton that pairs perfectly with a visit to Burney Falls.
Just beyond the famous waterfall, Lake Britton’s main beach offers a wide arc of shoreline with designated swimming, nearby parking, and shaded picnic tables under tall pines. The water here warms up earlier than at the higher-elevation lakes, making it a comfortable place for kids and more hesitant swimmers. Many visitors walk the falls loop in the cool of the morning, then settle in at the beach for an unhurried afternoon of swimming, lounging, and watching boats drift past.
03
Best for camping by the water
Eagle Lake – Gallatin Beach
North Shore Of Eagle Lake • Wide-Open Lakefront Beach • Ideal For Multi-Day Stays
A long, gently sloping beach backed by campgrounds on the broad blue expanse of Eagle Lake.
Gallatin Beach sits on one of Eagle Lake’s most inviting stretches of shoreline, with easy walk-in access from nearby campgrounds and day-use parking. The beach tapers gradually into the water, so you can wade out a good distance before it gets deep, and there is plenty of room to spread out even on busy summer weekends. Evening brings big-sky sunsets over the lake, and many regulars linger on the sand to watch the colors fade before wandering back to camp.
04
Best cross-border escape
Goose Lake State Recreation Area Beach
Goose Lake Valley • Shady Lakeside Lawn And Beach • Relaxed Picnic-And-Swim Spot
A grassy, tree-dotted lakeshore with small beach areas that feels more like a park than a remote frontier lake.
On the north end of Goose Lake near the Oregon–California line, this state recreation area offers an easygoing mix of lawn, shade trees, and access to the broad lakebed when water levels allow. It is the kind of place where families bring lawn games, unfold a blanket, and wander down to the shoreline for a cooling dip between picnic rounds. Conditions on the lake can change with drought years, so locals often check in advance, but when the water is up it is one of the more relaxed places in the region to spend a hot afternoon.

Quietest option close to Canby
Big Sage Reservoir Shoreline
West Of Alturas • Remote, Uncrowded Reservoir Shore • Best For Solitude Seekers
A rough-around-the-edges high-desert shoreline where you can usually find your own private stretch of water.
Big Sage Reservoir does not have a groomed swim beach, but it makes up for that with open views, low-key access points, and a good chance you will share the shore with more hawks than people. Locals use small pullouts and informal coves along the edge of the reservoir for wading, cooling off, and launching kayaks or float tubes. It is exposed country with little built shade, so come prepared with plenty of water, sun protection, and a willingness to trade amenities for wide open space.
