Best Things to Do in Long Island for Young Adults

Visiting Long Island? Spend the day soaking up the sun at Jones Beach State Park, explore the stunning landscapes of Old Westbury Gardens, or wander through the scenic Planting Fields Arboretum. For a dose of fun, head to Adventureland for thrilling rides and entertainment. Whether you’re into nature, history, or adventure, Long Island has plenty to offer!

1. Catch a Wave at Jones Beach State Park

Long Island summers hit differently when you’re at Jones Beach State Park, especially with over six miles of sandy shoreline to explore. This beach is more than just sunbathing—there’s surfing at Field 2, volleyball courts, and a massive boardwalk perfect for people-watching and late-night strolls. I came for a quick swim and ended up staying until sunset.

Jones Beach Theater is just steps away and hosts concerts all summer, making it easy to pair a beach day with live music. If you’re into fitness, there’s also a two-mile fitness trail and bike path that runs along the coast. Surf conditions here are mellow in summer, making it ideal for beginners. Don’t forget to check the NYS Parks website for special events—they often host sand sculpting contests and beach festivals that bring extra energy to the scene.

2. Explore History at Old Westbury Gardens

Tucked into Old Westbury, this historic estate blends grand architecture with peaceful, photo-worthy gardens that are perfect for a relaxed day out. Touring the Westbury House feels like stepping into a different century—each room is filled with original furnishings and stories about the Phipps family who once lived here. I joined a guided tour and learned how the mansion played host to everything from political events to movie shoots.

Outside, the formal gardens stretch over 200 acres, with tree-lined walkways, reflecting pools, and seasonal flower beds that change with the month. I especially enjoyed the Walled Garden, which looked straight out of a storybook during spring bloom. They also host outdoor concerts, art installations, and even yoga on the lawn. If you’re looking for a slower-paced afternoon with plenty of charm, Old Westbury Gardens is one of Long Island’s underrated gems.

3. Stroll Through Blooms at Planting Fields Arboretum

Planting Fields Arboretum in Oyster Bay is a 400-acre oasis of greenhouses, themed gardens, and peaceful walking trails. It’s one of those spots that always feels fresh—whether you’re wandering the Italian Garden, the expansive Camellia Greenhouse, or wooded paths that lead to hidden sculptures and quiet benches. The variety of plant life here surprised me, especially the tropical collection blooming inside the conservatory during winter.

I visited during fall and the foliage was unreal—rich reds and golds that lit up every path. In spring, cherry blossoms steal the show, and the grounds become a favorite for photographers. You’ll also find events like seasonal flower shows, art exhibits, and occasional live music performances. Whether you’re after a quiet nature fix or planning a full afternoon picnic with friends, Planting Fields Arboretum is one of the most scenic places on Long Island to unwind.

4. Spin and Soar at Adventureland

Located in Farmingdale, Adventureland is Long Island’s go-to amusement park for fast rides, nostalgic games, and sugar-fueled snacks. It’s not huge, but it’s packed with energy—especially if you go on a Friday night when the lights and music take over the whole place. The Turbulence Coaster had me screaming, and I didn’t expect the Frisbee ride to hit that hard.

There’s a good mix of thrill rides and more chill options like bumper cars and the classic Ferris wheel, which gives great views at sunset. I also found myself hanging out in the arcade longer than expected—it’s a solid way to keep the fun going between rides. Lines move fairly fast, and they often host themed nights, so it’s worth checking their event calendar. Whether you’re coming for the adrenaline or the nostalgia, Adventureland makes for a fun group outing.

5. Jam to Live Beats at Jones Beach Theater

Northwell Health at Jones Beach Theater isn’t just a concert venue—it’s one of the most unique places to catch live music in the Northeast. Built right along the shoreline, the stage backs up to the open water, creating an epic view behind the performers. I caught a summer show here with friends, and watching the sun set behind the amphitheater made it even more unforgettable.

The venue hosts everything from big-name tours to throwback lineups, with acts like Dave Matthews Band and Post Malone hitting the stage. You’ll want to grab tickets early—good seats go fast, and popular shows usually sell out. Arrive before the crowds to snag parking and explore the boardwalk before showtime. With ocean air, a stacked lineup, and great acoustics, Jones Beach Theater delivers a concert experience that feels way more special than your average arena show.

6. Navigate the Night Sky at Vanderbilt Planetarium

Located on the grounds of the Vanderbilt Museum in Centerport, the Charles and Helen Reichert Planetarium blends science, visuals, and music for a night out that’s anything but ordinary. I visited during their Pink Floyd laser show, and the mix of lights and sound under the domed ceiling was hypnotic. It’s definitely not just for kids—it’s a full sensory trip.

Beyond the special events, the planetarium hosts guided astronomy shows where you can explore stars, galaxies, and planetary systems. The seating is comfortable, and the sound system is surprisingly good. Check their calendar for themed nights, like Beatles laser shows or live stargazing events. If you’re into astronomy, music, or just want something low-key but cool, this is a great spot. It’s also right near the harbor, so you can grab dinner nearby and turn it into a relaxed night out.

7. Solve Mysteries at Can You Escape? LI

Can You Escape? LI in Islandia offers an adrenaline-pumping way to spend an hour with friends, especially if you like teamwork and puzzles. I tried their Zombie Room, and it was way more intense than expected—we were solving riddles while the clock ticked down fast. Every room here is story-driven, from treasure hunts to sci-fi escapes.

The sets are surprisingly immersive, and each challenge is designed to test your communication and creativity under pressure. It’s not just about solving locks—it’s about stepping into a real scenario and thinking fast. Whether you’re with friends, coworkers, or on a date, it’s a great way to bond and laugh over your successes (or hilarious fails). Book ahead—weekend slots go quickly, especially for larger groups. If you’re looking for a break from the usual night out, Can You Escape? LI keeps things fun and unpredictable.

8. Rally at Riverhead Raceway

For a different kind of thrill, head to Riverhead Raceway, one of the last remaining NASCAR-sanctioned tracks in the Northeast. The sound of engines revving, the scent of burnt rubber, and the close-up view of short-track racing make this a high-octane experience. I went on a whim one Saturday, and by the end, I was yelling louder than the regulars.

Races range from figure-eight competitions to demolition derbies, and the stands get lively fast—expect die-hard fans and lots of local flair. There’s food, beer, and a welcoming vibe even if you’re totally new to motorsports. Check their schedule ahead of time for themed nights, fireworks shows, or classic car events. For something off the beaten path and packed with energy, Riverhead Raceway delivers excitement you don’t often find on Long Island.

9. Scale New Heights at Island Rock Climbing Gym

If you’re craving something active indoors, Island Rock Climbing Gym in Plainview is one of Long Island’s best spots to challenge yourself. The gym features a wide range of climbing walls, from beginner-friendly routes to overhangs that test both grip and nerve. I hadn’t climbed in years, but the staff helped me get comfortable quickly with a short intro session.

You’ll find bouldering areas, auto-belays, and top-rope climbs, making it great whether you’re solo or with friends. They also offer classes and weekly climbing nights for different skill levels. After an hour on the wall, I was exhausted in the best way. The vibe here is laid-back and welcoming—no pressure, just encouragement. If you’re into fitness with a mental twist, Island Rock gives you a full-body workout and a dose of problem-solving all in one session.

10. Catch the Thrills at Splish Splash Water Park

When the summer heat kicks in, Splish Splash Water Park in Calverton is the ultimate cool-down spot. This 96-acre park has everything from mellow lazy rivers to high-thrill slides like Dr. Von Dark’s Tunnel of Terror, which caught me completely off guard with its surprise drops and pitch-black turns.

There are over 20 rides, including Bombs Away, where you free-fall from a trapdoor, and the classic wave pool, which is perfect for groups. I went with a few friends and we split the day between rides and lounging in shaded cabanas near the food court.

Lines can get long by mid-day, so arriving early helps. They offer lockers and fast passes, both worth considering on busy weekends. Whether you’re chasing adrenaline or just looking for a fun way to stay cool, Splish Splash delivers a full day of water-fueled excitement.

11. Battle It Out at Long Island Laser Bounce

Located in Levittown, Long Island Laser Bounce is a neon-lit playground that combines laser tag, arcade games, and just the right level of chaos. The laser tag arena is multi-level, dimly lit, and full of hiding spots—ideal for sneaking up on your friends. I joined a walk-in group one evening and ended up teaming with a bunch of college students. Total blast.

Besides laser tag, they’ve got everything from skee-ball and air hockey to VR experiences and retro games. It’s a great place for group outings, birthdays, or just letting off steam. Weekends can get crowded, so book ahead if you’re going with a group. Wear comfy shoes—you’ll be running around more than you think. For low-pressure fun that still gets your heart rate up, Laser Bounce is a reliable go-to.

12. Roll Into Fun at United Skates of America

If you’re looking for a throwback activity that still hits today, United Skates of America in Seaford is the move. This classic roller rink blends retro vibes with modern fun, offering themed skate nights, live DJs, and a solid mix of music that keeps the energy high. I went for 80s Night and ended up staying way longer than expected—there’s something about skating in a circle that never gets old.

The rink is open year-round and caters to all skill levels, with skate rentals available on-site. They also have an arcade and snack bar, which makes it easy to take breaks and hang out between laps.
