The question “Where do the Cascade Mountains start and end?” isn’t new to those fascinated by this major mountain range. The Cascade Mountains, also known as the Cascade Range or Cascades, start at Lassen Peak in Northern California and end at Fraser River in British Columbia, Canada.

The Cascades is part of the Pacific mountain system of western North America. It spans over 700 miles through the states of Washington, Oregon, and the southern part of British Columbia in Canada.

This mountain range is a dynamic ecosystem offering impressive landscapes and various recreational opportunities.

Whether planning a day trip to soak in the sights or looking to embark on a week-long expedition, this guide has insider tips to ensure your journey is as seamless as it is breathtaking.

Let’s guide you to:

• The starting points of journeying the Cascades
• The most accessible national parks and campsites
• The must-see trails that promise an immersive experience
• Understand why renting an RV is the perfect way to experience the Cascades

The Cascade Range, known for its geological diversity, starts its northward journey in Northern California at Lassen Peak (also known as Mount Lassen), which is the southernmost volcano in the chain.

It then carves through the landscape, crossing Washington and Oregon states until reaching the northern point in British Columbia’s Fraser Valley.

Within the Cascade Range, there are volcanoes, both active and dormant. Key among them are:

• Mount St. Helens, known for its 1980 eruption
• Mount Rainier, the tallest at over 14,000 feet

These volcanoes are part of the Pacific Ring of Fire and indicate ongoing geological activity in the Cascade Range.

But the Cascades are not just volcanoes. As one travels north past the Columbia River, there are non-volcanic mountains often referred to as North Cascades. These include:

• Mount Stuart is the second highest non-volcanic mountain in the state of Washington, after Bonanza Peak. It’s part of the Stuart Range.
• Mount Shuksan is known for its dramatic ridges and glaciated peaks, it is one of the most photographed mountains in the world.
• Eldorado Peak is known for its knife-edge ridge, offering a challenging climb and stunning views.

With the transition from volcanic to non-volcanic peaks, there is a varied landscape of jagged ridges, alpine meadows, and ancient forests. This makes the range an excellent patch of natural history.

Historical Fact: American explorers Meriwether Lewis and William Clark passed through the Cascade Range in 1806 during their expedition to the northwest. They journeyed through the deep Columbia River Gorge on the border of Washington and Oregon.

There are several starting points when you want to embark on a journey through the Cascades. And each of these points offers a unique window into the mountain range’s beauty.

Here are a few starting points:

• Columbia River George is perfect if you’re going towards the southern routes. Here, the river carves a natural boundary between Oregon and Washington, providing an entryway into the heart of the Cascades with views of waterfalls and the towering Mount Hood in the distance.
• The Fraser Valley in British Columbia is excellent for those starting from the north. It is a gateway to alpine adventures. Here, the farmlands and valley set a backdrop of rising peaks and rugged landscapes ahead.
• North Cascades Highway (Highway 20), which passes through the Washington section of the range, is perfect if you want to see mountain views, lakes, and forest canopy.
• Interstate 5 is a great starting point if you want to go through the range in a more direct approach. While it lacks the charm of scenic routes, it compensates with efficiency and accessibility by linking major urban centers like Seattle and Portland to the mountain wilderness.

The Cascade Mountains offer national parks and trails for outdoor activities. Key examples are the North Cascades and Mount Rainier National Parks.

North Cascades National Park is perfect for solitude-seekers and offers a variety of experiences. It is also less crowded and has trails such as:

• The family-friendly Trail of the Cedars and Diablo Lake paths
• The demanding Cascade Pass and Desolation Peak treks

Mount Rainier National Park, anchoring Mount Rainier, also presents its own set of trails through ancient forests such as:

• The Nisqually Vista trail gives a gentle, family-friendly loop to enjoy the mountain’s beauty.
• The Wonderland Trail surrounds the entire base of Rainier, offering a multi-day journey through diverse ecosystems—perfect for seasoned backpackers.

We also have the Pacific Crest Trail which cuts through the Cascades. It offers a linear pathway through varying landscapes.

Adventure Tip: For a shorter trip, consider the Sunrise area of Mount Rainier, where trails of all difficulties offer breathtaking views of the peak and the surrounding valleys.

Traveling through the Cascades doesn’t mean you have to leave the comforts of home behind. With Recreational Vehicles (RVs) and equipped campsites, you can bring your home with you.

The Cascade Range has RV-friendly spots where you can park and enjoy the surroundings. For example:

• The Alpine RV Park and Campground offer full hookups, Wi-Fi, and classic campfire rings for that authentic camping experience.
• The Big Fir Campground and RV Park, where the towering firs offer a protective canopy, is perfect if you want a humbling connection to nature. It has amenities such as pull-thru sites, electric hook-ups, sewer and water connections, Wi-FI, and picnic tables.

You can rent an RV and journey through the Cascades. Remember to consider the logistics of permits and reservations because national parks and campgrounds can fill up quickly during peak season.

The benefits of renting an RV for a journey through the Cascades include:

• Flexibility: An RV rental gives you the freedom to tailor your travel plans. You can decide your own stops and breaks, and even change your route on the go.
• Ease of use: With an RV, you have the space to carry all your essentials, from outdoor gear to your beloved pets. It also allows for spontaneous stops whenever you come across an interesting sight or need a break.
• Home-like comfort: RVs bring the comforts of home to your journey. They come equipped with beds for a good night’s sleep and a kitchen for home-cooked meals.
• Cost-effective: Compared to the combined costs of hotels, dining out, and air travel, RV rentals can be a more budget-friendly option for long trips.
• Trial run: Renting an RV can be a great way to test if the RV lifestyle suits you before you decide to buy one.
• Eco-friendly: By reducing the need for hotel stays and dining out, RVs can help lower your travel’s environmental impact.

Choose your route wisely to get the most out of the drive when planning your trip. Here is a guide to help you navigate:

Scenic Byways and Highways

• Cascade Loop Scenic Highway: This is a favorite for many, encompassing views of both the western and eastern sides of the range. It offers a diverse array of landscapes, from lush evergreen forests to arid desert-like valleys.
• Mountains to Sound Greenway (I-90): Providing a direct route through the Cascades, it connects Seattle with the eastern parts of Washington and includes the stunning Snoqualmie Pass.
• Route 12 (White Pass Scenic Byway): This lesser-known route crosses the southern part of the Cascades and offers breathtaking views and fewer crowds.

Road Conditions and Seasonal Closures

The Cascades are known for heavy snowfall and unpleasant weather which results in seasonal closures. This is common on the higher passes like North Cascades Highway (Highway 20) which typically closes in winter.

Check the current road conditions before departure, especially during seasons when weather can be unpredictable.

Also, tire chains or all-wheel drive may be required during winter months.

Did You Know? Crater Lake, known for its deep blue color and clear water, is the most famous among the many lakes within the Cascades.

Alternative Transportation

Local shuttle services like the Cascade Shuttle offer convenient access to popular trailheads for those without a vehicle or who prefer not to drive. This allows hikers to traverse the mountains without needing a personal vehicle.

Some national parks and tourist areas may have their own shuttle services during peak seasons. This reduces the need for finding parking spots. Also, limiting the number of vehicles in the park helps to reduce traffic, noise, and emissions which aids in conservation efforts.

Transportation Tips

• Start early to avoid afternoon clouds or storms that can obscure the mountains.
• Fill up your gas because gas stations can be few and far between, especially on the more remote routes.
• Carry emergency supplies, such as extra water, food, and a first-aid kit when going into less populated areas. These can be a savior in case you’re stranded.
• Always let someone know your planned route and expected return, especially if you’re heading into the backcountry.

When exploring the Cascade Range, it’s important to remember the principles of Leave No Trace. This helps preserve its natural beauty for future generations.

The seven Leave No Trace Principles include:

1. Plan ahead and prepare: Before you set out, know the regulations and special concerns for the area you’ll visit. Prepare for extreme weather, hazards, and emergencies.
2. Travel and camp on durable surfaces: Stick to established trails and campsites. Walk single file in the middle of the trail to avoid widening it.
3. Dispose of waste properly: Pack it in, pack it out. Inspect your campsite for trash or spilled food. Pack out all trash, leftover food, and litter.
4. Leave what you find: Preserve the past and the environment. Examine but do not touch cultural or historic structures and artifacts. Leave rocks, plants, and other natural objects as you find them.
5. Minimize campfire impacts: Use a stove for cooking and enjoy a candle lantern for light. Use established fire rings, pans, or mound fires where fires are permitted.
6. Respect wildlife: Observe wildlife from a distance. Do not follow or approach them. Never feed animals. Protect wildlife and your food by storing rations and trash securely.
7. Be considerate of other visitors: Respect other trail users and protect the quality of their experience. Be courteous. Yield to other users on the trail.

Safety is always more important than reaching your destination. Consider the following safety tips:

• Weather awareness: Mountain weather can be unpredictable. Check forecasts ahead of your trip and be prepared for sudden changes in weather conditions.
• Wildlife encounters: Store food in bear-proof containers when necessary, and know what to do in the unlikely event of a bear encounter. Stay calm, do not run, and slowly back away while facing the bear.
• Stay oriented: Use a map and compass or a GPS device to avoid getting lost. Remember that cell service may be unreliable or non-existent in remote areas.
• Emergency readiness: Carry a first-aid kit and know how to use it. Learn the signs of hypothermia, dehydration, and altitude sickness.
• Hiking preparedness: Wear appropriate footwear, carry sufficient water, and dress in layers to adapt to changing temperatures.
• Group dynamics: Never hike alone, and always inform someone outside your group of your travel plans.

Journeying through the Cascade Mountains should be on top of your to-do list. It will offer you a good chance to connect with nature while creating unforgettable memories with friends and family.

But you don’t have to sweat it out, especially in terms of transportation. Rent an RV for your adventure, thanks to the abundance of RV-friendly stops within the Cascade Range.

An RV adventure allows you the flexibility to create lifelong memories without compromising homely comfort.

So, whether you’re a seasoned hiker, a nature enthusiast, or someone looking for a new adventure, it’s time to explore the Cascades in an RV.
