If you are planning a trip to North Cascades National Park with kids, you are probably wondering what exactly there is to do in the park for families.

- Pro Tip: Pack a trail lunch! There are wooden benches along the paved lake deck, making it one of the most scenic picnic spots along Highway 20.

Located right behind the North Cascades Visitor Center in Newhalem, the River Loop Trail is a great option for families looking for a gentle, low-stress hike through mossy old-growth forest.

From the top, you get sweeping aerial views of the bright turquoise water framing surrounding mountain peaks.

Essential Packing Tips for Hiking North Cascades With Kids
- Bring Layers: Mountain temperatures can change quickly. Even on warm summer days, high-elevation trailheads can feel chilly. Pack light windbreakers or fleece jackets!
- Proper Footwear: While Rainy Lake is stroller-friendly, trails like Thunder Knob and Blue Lake can have uneven paths with rocks or tree roots. Sturdy sneakers or kid-friendly hiking shoes are a must – my kids love these Merrell Trailblazers!
- Bug Spray & Sunscreen: Alpine lakes and forests bring mosquitoes, especially in July and early August. Keep bug spray readily accessible.
- Leave No Trace: Help keep North Cascades pristine by teaching kids to stay on marked trails, pack out all trash and snack wrappers, and leave wildflowers for everyone to enjoy.
