Susquehanna National Heritage Area (SNHA) has posted upcoming activities.

River Discovery Boat Tours aboard the historic Chief Uncas will be available this summer. Tickets for one-hour tours as well as sunset cruises may be purchased at https://susqnha.org/programs/boat-tours/.

The Pennsylvania Fish and Boat Commission's annual Fish for Free Days will be Sunday, May 26, and Thursday, July 4. On these days, residents and non-residents may legally fish without a fishing license. SNHA will allow visitors to borrow fishing poles and child-sized life jackets. The equipment must be used in Columbia River Park and returned by 5 p.m. the same day it is borrowed. To sign out gear, stop by the front desk at the Columbia Crossing River Trails Center, 41 Walnut St., Columbia. SNHA encourages everyone, particularly kids, to wear life jackets when close to the water.

Tadpole Time will be available for kids ages 2 to 5 and their caregivers on Wednesday, June 12, at 10:30 a.m. The program, focused on fireflies, will include a story and other activities. There is a fee for those who are not residents of Columbia.
