Seattle to North Cascades National Park Day Trip Itinerary

Get ready to embark on an unforgettable day trip from Seattle, where you’ll experience the breathtaking beauty of North Cascades National Park.

This carefully curated itinerary will take you to three must-visit destinations: the awe-inspiring Diablo Lake, the Diablo Lake Overlook, and the stunning Washington Pass Overlook. But that’s not all – along the way, you’ll have the opportunity to stretch your legs at picturesque waterfalls, scenic overlooks, and the wild and scenic Skagit River.

For our family, North Cascades National Park attractions holds a special place in our hearts. We’ve explored its diverse landscapes in every season, and it remains one of our favorite destinations, drawing us back year after year.

We did this itinerary with our out-of-town visitors who were visiting North Cascades for the first time. With a group of four adults and three children ranging from 3 to 12 years old, this day trip became one of our most cherished and memorable adventures, perfectly suited for families and outdoor enthusiasts alike.

North Cascades Day trip Itinerary

Morning

1.1 Drive from Seattle to North Cascades National Park (2 – 2.5 hours)

North Cascades National Park is accessible via SR 20 and the largest unit of the North Cascades National Park Complex (other two being Ross Lake and Lake Chelan National Recreation Areas).

We begin our trip from Newhalem, which is the first town after you enter North Cascades National Park. Expect the drive to take anywhere between 2-2.5 hours if coming from Seattle. Before entering the park, you will pass Rockport and Marblemount on SR20 which are your last stops to get food, water, gas.

Coming from Seattle, you can take one of the two routes to get to State Route 20 –

Via State Route 530 – From I-5 North, take exit for SR530 from Arlington which joins SR20 at Rockport. You will pass the town of Darrington on this route where you can enjoy the views of Whitehorse Mountain peak and grab a burger and milkshake at Burger Barn.

Via State Route 20 from Burlington – From I-5 North, take exit for SR 20 from Burlington. You can pick up food on the go from one of the many restaurants in the area.

Regardless of the route you take, the drive throughout is spectacular. I would recommend starting as early as you can and avoiding any unnecessary stops as you have a long and active day ahead. We started our trip around 8:30-9am and reached Newhalem by 11am.

Afternoon

1.2 Suspension Bridge to Trail of the Cedars (1 hr)

The first stop on SR 20 is at Mile 120 – Trail of the Cedars near Newhalem, which starts with a suspension bridge and then continues for a 0.3 mile loop.

After a 2-hour long drive and the intermittent views of the beautiful Skagit river along the way, this stop will allow you to view the flowing river up close as well as take an easy walk that will serve as a good leg stretcher after all the driving.

Suspension Bridge – Located near Skagit Information Center at Newhalem, a walk over the suspension bridge provides some amazing views of the emerald-turquoise green Skagit river. Bridges are always fun, especially for kids. You can enjoy the views and turn back or continue on the Trail of Cedars.

Trail of Cedars – Upon crossing the suspension bridge, you can walk the the Trail of Cedars which is a 0.3 mile RT flat and easy trail. It is a walk in the woods with interpretive signs to educate you on the wonders of the forest. The Skagit river flows right by the trail providing flowing sounds and beautiful sights along the way.

If you are going with younger kids and don’t expect to hike a lot on your trip, then Trail of Cedars is a great option to get some light activity earlier in the day. On long driving trips, you have to let the kids loose intermittently to get their wiggles out. 

Back to the parking – You can make a quick stop at the Skagit Information Center for more information on the area through its informational boards and map displays. You will also find a a locomotive engine placed on the premises. Access to clean restrooms makes this a convenient stop.

Substitutes – Since the goal is to take a leg stretcher break, there are a couple of other scenic options around Newhalem between Mile 119 to Mile 123 on SR20 that you can consider. 

• You can stop by North Cascades Visitor Center and do the short Sterling Munro Boardwalk for views of Picket range. 
• Ladder Creek Falls and Garden with a 0.4 mile RT trail. Or save it as a stop for your return journey as these falls are lit up every night from dusk to midnight.
• Gorge Creek Falls (~240ft) and Gorge Lake Overlook Trail (0.8 miles RT). As the name suggests, the trail takes you to an overlook with views of Gorge Lake. 

You can also spend 2-3 hours around Newhalem and cover multiple of these stops, but then you will have to shorten subsequent activities from the day, so boils down to your preference.

1.3 Diablo Lake (1-2 hours)

The second stop on our day trip is at Mile 130/131 – Diablo Lake. You will have most likely seen the jaw dropping pictures of Diablo Lake which pulled you to North Cascades National Park in the first place. The views will not disappoint.

The most accessible place to get close to Diablo Lake shores is near Colonial Creek campground / boat launch area. You will see many cars parked alongside the road so try and find a spot around that area.

The walk to the lakeshore is short and easy. And the shoreline is long enough to accommodate multiple families. There are some trees near the shore that can provide natural shade and a place to tie your hammock.

We stopped here for lunch so took a good 1-2 hour stop here. Bring prepacked food or carry your camping stove for picnic by the lake.

The water is cold even in peak summer, but kids will enjoy nevertheless. This is a great place to launch an inflatable kayak / boat / paddleboard if you are carrying one. Sit by the lake and soak in all the views. The milky green-blue colors of the lake water will stay with you for a long time.

1.4 Diablo Lake Vista Point (0.5-1 hour)

Diablo Lake Vista Point is the next stop on the route and 5 mins drive from Colonial Creek campground. This is one of the highlights of the trip and a must-visit. The overlook is large with easy accessibility, ample parking and restrooms. There are many picnic tables here and this too makes for a great lunch spot, but it can get windy!

The views of Diablo lake and its gorgeous colors will only feel enhanced from the top. The lake color can look different depending on the sun. Pictures don’t do justice to the actual views. The ones above were taken on a ‘not-so-sunny’ day and it still was breath taking.

The lake gets its jaw-dropping turquoise blue color from glacial silt that reacts with light and it is most radiant when the sun is out. The surrounding mountain peaks enrich the landscape. The interpretive boards will give you a good overview of the history and geology of this place.

Other things to do – Some other options between Mile 130 to Mile 136 on SR20 which can serve as as additional scenic stops along the way are listed below.

• Ross Lake Overlook – It is accessible off of SR20 and makes for a quick pitstop with views of Ross Lake and surrounding mountains.
• Ross Dam Trail – This is a 1.5 mile RT / 500 ft elevation gain trail that will take you to the top of Ross Dam.
• Happy Creek Trail – It is 0.3 mile to 2.6 mile easy and kid-friendly trail.

Evening

1.4 Washington Pass Overlook (2 hours)

Next we head upto Mile 171 to Washington Pass Overlook which is our last ‘big attraction’ before we turn back and start on our return journey back home. 

Drive and Amenities – From Diablo Lake Vista Point, it is 30 miles / 35 mins drive (one way) and this part of the road is closed Nov-June. As you drive, you will feel the wilderness and remoteness around you.

Different mountain peaks will show themselves at different turns in the road.  There is plenty of parking and vault toilets at the overlook entrance. There are picnic tables too.

It is important to note that you will be taking ~1.25 hrs of round trip driving for just one spot where you can expect to spend up to an hour. Some save the visit to Washington Pass Overlook as a stop on the way to Mazama on a longer trip. So another option is to spend this chunk of time on other options between Newhalem and Diablo Lake.

But if you are here with visitors, then I’d recommend making the effort to cover Washington Pass Overlook as it is a stop not worth missing.

At Washington Pass Overlook –  There is a paved 0.25 mile trail from the parking lot to the overlook that provides the most breath taking views of Liberty Bell Mountain, Early Winters Spires and Kangaroo Ridge. Nowhere else can you experience the alpine wonderland all around you with such an easy short walk.

From the spires and ridges rising all around to the winding Highway 20 below, there are no words to describe the feeling of being in this spot, it  almost feels meditative being here. Keep following the trail to enjoy these views from different vantage points. There are some stairs and steep grades on the loop back but nothing that is not manageable with kids. If you are facing mobility issues, then its best to turn back on the flat path you took on your way to the overlook.

In fall, you can see larches. During a late fall visit, we were fortunate to see a spectacular moon rise behind Kangaroo Ridge with light dust of snow on the peaks. That remains our most special and memorable visit to date.

Other things to do in the vicinity – Rainy Lake Trail (2 miles / 70 ft elevation gain) and Cutthroat Lake Trail at Mile 167 (3.6 miles/400 ft elevation gain) are easy and kid-friendly trails in this stretch. These also make great spots to view larches turning golden in fall.

1.5 Drive Back to Seattle + Optional Stops (3 hours)

Drive back – From Washington Pass Overlook, expect 3 hours drive to Seattle if you are not taking any stops – about 2 hrs to Burlington back on SR 20 , and then ~1 hour south on I-5 to Seattle. 

Optional Stops – If you are with kids, then you maybe compelled to break up the journey a bit if kids are getting restless. Ladder Creek Falls with its night lights and/or Gorge Creek Falls along SR 20 are quick and easy options to stop at, on your way back. These stops will come after an hour’s drive from Washington Pass Overlook.

1.6 Food / Dinner

For food / dinner options along the route – 

• Concrete – There are a handful of restaurants near Concrete on Highway 20. Birdsview Diner, Miga Asian, Annie’s Pizza Station and 5b Bakery are some options to consider provided they are open on the day of, and if you reach at an earthly hour. Concrete will be 1.5 hr drive from Washington Pass Overlook and ~45 mins drive from Ladder Creek Falls / Newhalem.
• Burlington – There will be many options at Burlington, from quick service restaurants to bars to something more elegant. A google or yelp search can help you here. Burlington will be 2 hr drive from Washington Pass Overlook and 1 hr drive from Ladder Creek Falls / Newhalem.

Once you hit I-5 at Burlington, the drive to Seattle will be 1 hour or so. Expect to be exhausted by this time. Great to get kids changed as they are likely to doze off on the way back.

Tips for Visiting North Cascades National Park

Seattle to North Cascades National Park Trip Planning

• Summer day trip – There is no one way to visit national parks, so consider this itinerary a starting point for your own trip planning. We followed this itinerary when taking out-of-town visitors to North Cascades National Park in an attempt to provide a glimpse of the best this park has to offer. With a group of 4 adults and 3 kids (3,7 and 11 year old), this mix of stops and pace served us well. This will be a long but a very memorable trip, expect to be tired by end of the day. We started our day at 8:30am and were back home at 10pm.

• Fall day trip – If visiting during fall, I’d recommend doing a hike that gives you an up close look of the turning fall colors and golden larches. Rainy Lake or Maple Pass are good options.

• Winter day trip – If visiting in winter months like we did in November, then the road from Milepost 136 to 171 will be closed. So you can plan your trip considering attractions between Newhalem to Ross Lake Overlook at that time. We visited the Diablo Lake Dam, Diablo Lake Vista Point and Gorge Lake Overlook trail.

• Best time of year to visit North Cascades National Park – Summer is when the park is the most accessible for a longer day trip or a multi-day road trip. So summer is the best time for a first-time visitor. As locals, we have visited North Cascades National Park in July, early October and late November taking different stops and hikes, and this park is stunningly gorgeous in each of these months.

Parking, Food and Amenities

• Entrance Fees – There is no entrance fee for this park. But some trailheads require Northwest Forest Pass.

• Cellular network – No cellular network within the park.

• Food – There are no food options once you enter North Cascades National Park, so plan to carry food and water. Marblemount is the last stop to get food, water gas before you head into the park. Mazama is a similar town on SR 20 on the east side for replenishments.

Stay

Rockport and Marblemount on the western side of SR20 and Mazama on the eastern side of SR20 are the closest towns to find accomodation if you are planning a longer trip.

If I were planning a longer trip starting from Seattle or going west to east, I would use the above itinerary for my Day 1 in North Cascades National Park and then head to Mazama for an overnight stay.

While finding accomodation in these small towns can be hard, other options would be any lodging between Burlington to Concrete in the west and between Mazama, Winthrop and Twisp to the east.

Final Thoughts

While North Cascades National Park boasts over 500,000 acres, with 93% designated as wilderness, this itinerary is designed to provide a tantalizing glimpse into the park’s breathtaking landscapes.

It’s a kid-friendly and family-friendly introduction that will leave you in awe of the sights and colors that make this place truly extraordinary.

So pack your sense of adventure, along with plenty of food and water, and get ready to be blown away by the awe-inspiring beauty that awaits you in North Cascades National Park.
