North Cascades National Park

Whatcom County's violent crime rate of 364.3 per 100,000 residents is the standout concern for visitors heading to North Cascades, outweighing a nearly negligible weather hazard record that logged just one heavy-rain event and zero injuries or deaths in the tracked period. While the park's remote terrain naturally limits exposure to urban crime, trailhead parking areas and gateway towns along Highway 20 are where that county-level risk is most likely to intersect with your trip.

Keep valuables completely out of sight in your vehicle — a bag on the seat is enough to invite a smash-and-grab at a trailhead lot. Use a hardshell lockbox bolted to your truck bed or RV storage compartment for cameras, wallets, and electronics. When stopping in Marblemount or Concrete for supplies, treat your rig the same way: lock up, take your key documents with you, and park in well-lit, visible spots rather than back-lot corners.
