Things to Do in Waltham

As the sun makes its retreat into the horizon, the whales of Stellwagen Bank National Marine Sanctuary come out to play. Their elephantine fins slap the waters with such zeal that the pod seems to be putting on a performance for the catamaran of whale watchers in their midst. This end-of-day nature show experienced by passengers aboard Boston's Best Cruises’ New England Aquarium Whale Watch is hardly a rarity, as the ship’s crews guarantee sightings of these gentle giants with each excursion.

Champions of the natural beauty of Boston Harbor and the area’s rich maritime history, Boston's Best Cruises’ expert crew sets sail on cruises to suit all manner of interest. Along with their whale watches, Boston’s Best Cruises whisks passengers away on Harbor Cruises that grant unimpeded views of the Boston skyline and the King Kongs pumping fists within its skyscrapers. The Salem Ferry facilitates leisurely cruises between Boston and the historic city, and aquatic outings to the Boston Harbor Islands National Recreation Area enable activities such as sunset clambakes, hiking, and fishing.

At The Clayroom, an evening spent decorating bisque pottery pieces can spark conversation and unleash each guest's inner artist. Visitors hunker down next one of the studio’s two working fireplaces and work on their selected pottery pieces. After choosing anything from coffee mugs or butter dishes to cereal bathtubs, painters brush on various paints to create their own inimitable pieces of art. The studio kicks open its doors for birthday parties and baby showers, and hosts weekly events as Pizza Night and Wine and Cheese Night.

With three haunted houses, a spooky hayride, and a bustling carnival, Witch’s Woods is a Halloween theme park that rises from the mist for only one month a year. Ferried along by a sputtering tractor, Haunted Hayride passengers cower for 20 grueling minutes as they are assailed from all sides by zombies, werewolves, ghouls, and cows trying to nibble the hay. At the end of the ride, three paths lead to additional attractions, including Castle Morbid, in which medieval spirits chase interlopers through the halls and into the depths of the keep, where it becomes increasingly apparent that the weapons that once kept intruders out are now employed to keep them in. Nightmare Mansion is inhabited by a cursed family whose eternal life has left them as withered husks driven insane with rage at visitors who still possess the ability to die. The final path leads to the 3-D Keeper’s Crypt, where the undead shamble and scream as they pursue their prey, and where the walls themselves seem to be closing in.

A creepy carnival awaits survivors with rides, games, and more attractions. The Horror wood Chamber of Chills puts favorite Halloween and horror-movie characters on display, including such icons as Frankenstein, Freddy Krueger, and Mary Shelley’s original version of Shrek. Meanwhile, the Jack O’ Lantern Jamboree displays rows upon rows of professional carved pumpkins, eerily glowing at self-guided passersby.

Visitors to Mel's Funway Park can try their hand at two 18-hole mini-golf courses before speeding and swinging their way through the go-kart track and batting cages, which feature a replica of Fenway's Green Monster and slow- and fast-pitch machines that can reach speeds of up to 85 mph. Inside, a laser plex hosts games of laser tag, while other visitors attempt the laser maze, a web of 36 lasers that participants must avoid to keep from triggering the alarm and receive their cat-burglar certification. Funway Park has also partnered with Woodman's Restaurant to recharge empty body batteries with fare from a renowned and award-winning eatery.

Apartments, offices, restaurants, and shops occupy Kendall Square’s 10 acres, which also host a variety of seasonal events. In winter, an 8,400-square-foot ice rink welcomes skaters seven days a week, and Broad Canal is lined with farmers' market vendors slinging local produce, honey, cheese, and flowers during warmer months. Free summer concerts, cosponsored by the Berklee College of Music, take place in the square’s open-air plaza, and canoe and kayak rentals are easily available through Charles River Recreation. A dedication to green living guides all the action at Kendall Square, which is easily accessible by train, bike, Zipcar, and pogo stick.

Hidden among Strasburg's thicket of spindly trees, patchy grass, and dirt fields, castles and wooden forts stand strong while flying saucers hint of an alien invasion. This is all part of Skyline Paintball's battlefield landscape, which includes more than eight fields such as Mars Attacks and Frontier Fort. Before slinking through trenches and underground bunkers, players load up on fresh paintballs by Kee and GI Sportz, sold by Skyline onsite. Refs oversee matches to ensure everyone understands the finer techniques of pointillism and that no one uses a marker that fires faster than 280 feet per second. Players can walk on during open play each Saturday and Sunday or buy a group package for weekday melees during which up to 20 players can sling rainbows of paint throughout strategy-laden matches. For paintless competitions, Skyline also hosts laser tag sessions.
