Susquehanna RiverNorth Branch: Larnard Hornbrook Park to Terrytown PFBC

Twenty-one-mile North Branch Susquehanna continuation from Larnard Hornbrook Park to the Terrytown PFBC ramp. The official PFBC Section 1 guide publishes both access coordinates, supports the long distance with official river miles, and ties the whole route to the Towanda gauge for conservative same-day planning.

Distance, difficulty, rules and camping
On-water distanceAbout 21.5 miNorth Branch: Larnard Hornbrook Park to Terrytown PFBC
DifficultyeasyThis is still broad-audience flatwater in the conservative band, but the 21.5-mile length, exposed wind, and repeated quick-water zones make it a serious long-day commitment rather than a casual float.
ShuttleCar shuttleStage the take-out at Terrytown PFBC first, then drive back to Larnard Hornbrook Park. Inspect both landings before launching because mud, event traffic, flood cleanup, or local maintenance can change how straightforward the carry feels.
PermitsCheck posted rulesPFBC says unpowered boats using PFBC or Pennsylvania State Parks and Forests access areas need boat registration, a PFBC launch permit, or a DCNR State Parks launch permit. Follow current PFBC, county-park, borough, boating, and PFD rules.
CampingOptions nearbyHornbrook County Park and Riverside Acres Campground both sit on this official corridor and support legal overnight planning. Treat that as on-route camping support only and not as permission to camp on broad bars, islands, or private banks.
SeasonApr-OctPFBC says the North Branch often stays paddleable through summer low water, but broad-river wind, thunderstorms, and flooded treelines still change the feel quickly on a long day like this.

Route logistics

Access and shuttle

Launch at Larnard Hornbrook Park and take out at Terrytown PFBC for a long Section 1 Susquehanna continuation. Use the direct Towanda stage gauge, keep the easiest planning days around 2 to 4 feet there, and treat wind plus the repeated fast-water zones as real long-day factors.

This is a long mainstem day for a nominally easy river. The corridor is broad and mostly open, but the distance and weather exposure matter as much as the riffles.

Access caveats

  • PFBC Section 1 publishes both Larnard Hornbrook Park and Terrytown PFBC coordinates directly in the official access table.
  • This is a long mainstem day for a nominally easy river. The corridor is broad and mostly open, but the distance and weather exposure matter as much as the riffles.
  • Hornbrook County Park and Riverside Acres are helpful legal overnight supports, but the route still begins at Hornbrook and should finish at the Terrytown PFBC landing unless you have made a deliberate legal stop plan.
  • Stay within the named public accesses, campgrounds, and support points rather than treating islands or private banks as casual options.

Watch for

  • The mile-274 strainer area, current under bridge arches at mile 272, the Towanda bridge sequence, and the lower-section fast-water miles 267, 261, and 258 flagged by PFBC.
  • Towanda stages below about 1 foot, when shallower lower-riverbed spots can create class I to II style wave trains and expose more rocks.
  • Towanda stages above about 4 feet, when the current moves faster and small errors cost more energy late in the day; PFBC says novice paddlers should stay off above about 5 feet.
  • Headwind, thunderstorms, floating wood, fatigue, private shorelines, and drifting past the Terrytown PFBC finish after settling into the long lower-corridor rhythm.
