HOOD RIVER, Ore. — It was a good thing nobody warned me about all those hills and the cars zooming by.

Because if I'd known beforehand what the ride from the bike shop in Hood River to a nearby trailhead was going to be like, I might not have tried it. Especially not with my 9-year-old son, whose biking experience consisted of a loop in a mostly flat city park where cars are banned.

But we were determined to include biking on a three-day trip to enjoy outdoor adventures in Oregon, including visits to Multnomah Falls, the Mount Hood region, the Sea Lion Caves near Florence and the Oregon Dunes National Recreation Area. And despite my initial panic about the bike ride, along with another meltdown before I fell in love with dune buggies, all of our outings were terrific.

I'm a city girl but I try to appreciate the great outdoors, especially on vacation. And Oregon did not disappoint. From the Columbia River to the Pacific Coast, the scenery was astounding.

First stop for our family (two boys, me and my husband) was Multnomah Falls, which is part of the Columbia River Gorge National Scenic Area. The narrow waterfall is 620 feet high, bisected by a picture-perfect footbridge. A woodsy trail to where the falls begin is a steep mile up Larch Mountain. You'll pass lots of folks resting along the way. But the scenery is worth the exercise.

We overnighted at a hotel in Troutdale, then headed to the bike trail. If you do any recreational biking, you won't find it challenging to bike from the town center of Hood River to the Mark O. Hatfield Trailhead west, about a mile away. Within a few minutes, we were in the park on the 3.5-mile ride to the Mosier Twin Tunnels. The tunnels were closed in the 1950s but reopened in 1996 as part of the Historic Columbia River Highway State Trail.

Cars are not permitted on the trail, which is mostly paved, making it a pleasure for bikers and hikers. The road winds past fragrant evergreens, but the real payoff comes when the trail opens up to stunning views of the wide Columbia River.

It was beautiful and exhilarating. We bought fresh fruit at one of the many orchards and wineries along the way. As we rounded a bend, the snowcapped mountaintop came into view.

Nearby, Mt. Hood Adventure Park at Skibowl opens when most of the snow is gone.

My boys sampled bungee-jumping on a trampoline, zipline rides, the rock-climbing wall, go-carts, mini-golf and batting cages. We didn't have time for mountain-biking, but they did love the alpine slide, which involved taking a ski lift up a hill, and zooming down long, serpentine tracks in slippery little carts.

After a night at a hotel in Salem, we arrived the next morning at the Oregon Dunes National Recreation Area. Except for movies and TV, we'd never seen dune buggies before. I watched them race around, turn on a dime, drone and buzz, noting that they were constructed from little more than steel frames, wheels and benches with seat belts. Enormous goggles were required to protect eyes from the desert storm as they raced up and down towering dunes. They looked like roller coasters in the Sahara. I suddenly felt queasy.

I put on goggles and the seat belt, zipped my jacket up to my chin to keep out the sand, and braced myself.

Within a minute, this was more fun than an amusement park!

Last stop on our itinerary was far tamer. A colony of sea lions lives in caves by the ocean north of Florence, a few miles from the dunes.

While these sea lions don't ham it up like the critters who live on the pier in San Francisco, they are still fascinating. And the Pacific Coast setting, including the drive along Highway 101, is wild and gorgeous.

Yes, our family is more comfortable on city streets and subways than in the great outdoors. But our Oregon adventures were a blast.
