01
Best overall pick
Lake Camanche – North Shore Swim Beach
West Of Martell Near Ione • Lively Lakeside Swim Beach • Best All-Around Choice
A broad, managed swim area with warm water, easy parking, and plenty of room to spread out.
North Shore is usually the go-to beach day from Martell, with a wide roped-off swim area, gentle entry, and a social, easygoing vibe. Expect lawns, picnic tables, seasonal snack options, and nearby boat rentals if you want to get out on the water. It’s an easy drive down through Ione, but arrive earlier on hot weekends for the best shade and shoreline spots.
02
Close-to-town escape
Lake Amador – Swim Pond and Lakeside
South Of Ione In The Foothills • Family-Friendly Swim Pond And Lakefront • Best For Kids And Casual Lounging
A compact sandy swim pond backed by a quiet foothill lake, ideal for low-key family days.
Lake Amador’s small swim pond packs in a lot of fun, with a sandy edge, mellow water, and a laid-back, locals-first feel. A little store, nearby camping, and easy parking make it simple to turn a quick dip into a half-day hangout. It’s not a huge beach, so it feels cozy rather than sprawling, and it can fill up on the hottest summer afternoons.
03
Scenic reservoir day trip
New Hogan Lake – Oak Knoll Recreation Area
Near Valley Springs • Open Shoreline Reservoir Beach • Best For Combining Beach Time And Boating
A roomy stretch of reservoir shoreline with picnic spots, launch ramps, and big-sky views.
Oak Knoll offers a more open, natural-feeling beach experience, with sloping shoreline, scattered trees, and easy access to the water. The beach is more gravel and packed earth than fine sand, so water shoes are a smart bring, but the tradeoff is fewer crowds and broad views. Pair a swim with a picnic or a boat outing and you have a full day trip from Martell without feeling rushed.
04
Big-day outing
Folsom Lake – Granite Bay Main Beach
Northeast Of Sacramento • Busy State-Park Lake Beach • Best For Groups And Amenities
A long, groomed lakeside beach with patrols in season, concessions, and space for big gatherings.
Granite Bay has the feel of a classic summer beach day, just on a reservoir instead of the ocean: wide sand, designated swim zones, and plenty of people-watching. It’s a bit farther from Martell, but the payoff is solid facilities, multiple restroom areas, food options in season, and nearby trails if you want to stretch your legs. Water levels and shoreline size shift with the year, so expect a different look between early and late summer.
05
Forest-fringed retreat
Sly Park Recreation Area – Jenkinson Lake Swim Area
Near Pollock Pines • Shady Mountain Lake Cove • Best For Cooler Summer Days
A sheltered swim cove tucked into pines, with clear water and a relaxed mountain-camp feel.
Jenkinson Lake’s main swim area trades wide-open heat for tall trees and cooler mountain air, perfect when the foothills are baking. The beach itself is compact but pleasant, with nearby picnic tables, short shoreline trails, and easy access to the water for kids and casual swimmers. Come prepared for slightly cooler water and air temperatures, and you’ll get one of the most refreshing beach-style escapes within day-trip range of Martell.
