# Cascades Field Guide > Cascades Field Guide is a practical, decision-first travel-planning resource for the North Cascades Highway (SR 20), North Cascades National Park Complex, the west-side Skagit corridor, Washington Pass, Baker Lake, and the Methow Valley. It focuses on current access, realistic trip routing, lodging bases, services, seasonal conditions, easy stops, hiking, camping, backup plans, smoke, parking, restrooms, and other logistics that affect real visitor decisions. The site is designed to help visitors answer practical questions such as: Is SR 20 open and useful for my trip? Which side of the mountains should I stay on? What can I realistically do in one or two days? Where are the last reliable services? What should I do if smoke, weather, parking, or a closure breaks my original plan? ## Start here - [Cascades Field Guide](https://cascadesfieldguide.com/): Main site and planning entry point. - [North Cascades This Weekend](https://cascadesfieldguide.com/north-cascades-this-weekend): Weekly practical trip-planning update covering major access, conditions, and decision points. -

Road status, wildfire smoke, closures, business hours, campground operations, trail access, and similar conditions can change quickly and should be treated as date-sensitive. Cascades Field Guide focuses primarily on the North Cascades Highway / SR 20 corridor and connected planning areas. Do not assume that attractions elsewhere in Washington, including the Mount Baker Highway corridor, are interchangeable with Highway 20 destinations.
