Round Mountain is a road hike of about 2 miles one-way and 1000 feet of gain. It's close to Lookout Mountain-W7O/CE-039 so you might consider doing both of those peaks.Note that there are FIVE Round Mountains in Oregon, with one in CE near Lakeview. This is the Round Mountain east of Prineville.
Ochocco Mountains High Point could be considered a drive-up summit...for some vehicles. Although most of the way is paved, your low clearance passenger vehicle will have problems with the road in places where you can't turn around. A quarter mile of walking to the summit is recommended - it's a neat spot.
About 30 miles east of Prineville on Highway 26, turn north on Forest Road 27. This may be described as Grant Springs Road, or Summit Road, depending on your resource. This is near milepost 49.
One of our favorite summits in France, you can visit the winery and then hike up the road to the chapel and play radio! You can even stay overnight in accommodations at the winery. The hike is all of 1km with about 90m of rise. At the chapel there's a bench and some shade - a perfect spot to activate after wine!
It's perhaps easiest to find the summit by finding the winery: Chemin Notre Dame des Anges, 84570 Mormoiron. That's about an hour east of Avigion.
La Forêt is a forested one-point summit near La Motte-Servolex, France. Heading east on A43, just before the tunnel, exit at Lac d'Aiguebelette, pass through the toll plaza, take the first exit from the roundabout and then the next right. After you pass under the A43 and after about 400m, take a sharp left onto Route du Terreau and wind up the hills towards Ayn on D36E. Pass through Ayn and continue on D37 to Route du Montigon. A GPS will be quite useful in getting to the trailhead.

I've been up on Whale Head a few times and it looks like it's time to write up a trip report! This has been a "near drive-up" summit, however with the growth of slide alder into the road you may park and walk earlier that the gate.

Here's a nice 3 mile snowshoe or cross-country ski in the winter. OR...you may be able to drive within about a half mile in the summer. For a good ski experience, you might want to have at least 3 to 5 feet of snow on the ground - see the depth measure in the first photo below.
