The Land Trust is extremely pleased to be a major sponsor of the 4th Annual Waltham Riverfest, held every year over Father's Day weekend. Activities begin Friday afternoon with canoe/kayak rentals courtesy of Charles River Canoe and Kayak (CRCK). At 7 pm, for only $39, CRCK will lead a 3-hour guided history and nature paddle upstream to the flatwater Lakes District, where participants will anchor and dine on a boxed dinner under a star-lit sky, returning by 10 pm. Registration required (paddleboston.com/riverfest/riverfest.php)!Bluegrass bands play at the Cronin's Landing stage next to Margarita's, while rock bands like the Brooks Young Band and Liz Borden play on the Main Stage in Landry Park.

On Saturday, music starts early at the first Farmer's Market of the season, and paddle rentals begin at 10. Vendors sell their wares on a closed Moody Street Bridge and community groups like WLT, WATCH, and Healthy Waltham have tables at Landry Park, where music including the bluesy Peter Parcek, rocks the Main Stage. More bands, like local hero Mike Williams, jam at Cronin's Landing, while artists "paint the River" for a Silent Auction later that evening. An aerial artist, yoyo protege, and silly puppet show entertain families throughout the day. Activities wind down around 5 so everyone can review and bid on the river artwork, before partying-down to the head-lining musical acts on the Main Stage.

Sunday, we take it down a notch and focus on the family with more paddle rentals and a pet parade at 11 am in Landry Park. Bring your pooch to win prizes! At noon, the Land Trust leads a nature walk along the river, returning by 2 pm for the River Ceremony. Spoken word, a cappela groups, and world beat sounds fill Landry Park.

All weekend long, restaurants and businesses offer "wristcounts" to those wearing wristbands ($5). Stay tuned to the Riverfest website (walthamriverfest.org) for wristcount listings and performance schedules.
