See KJ7LSM's nice writeup of this summit. I'll only add that, in March 2025, the gate to the last leg of the road is closed (see the southernmost point of the hike,below, resulting in an 800 foot, 1.7 mile walk up the remaining gravel road. There's room for one or two vehicles at the Y in the road while still providing passage if someone with access wants to pass through the gate.

Panther Rock (drive-up)
A drive-up on quite good gravel roads (see below), with great views in all directions (fully logged following forest fire a few years ago).
I came in from the West, leaving the paved road at 44.97599, -122.50586. These subsequent gravel roads were good enough for any passenger car. Just watch for big rocks on the road. There's not much to say about this road. There were very few gates, and I didn't notice any signage near them (unlike below).
Table Rock near Silver Lake / Summer Lake
Table Rock lies between Summer Lake and Fort Rock in central Oregon. It's easily visible and obvious for miles--a large round platau surrounded by desert. Views are great, of course.
Summit 6389 (near Dog Lake)
This no-name summit just East of Dog Lake was the last of of three activations during the Annular Eclipse weekend of October 2023.
Barry Point
I decided to attempt Barry Point following the Annular Eclipse of 2023. I approached it from the South and drove clockwise to a point north of the peak where a dirt road heads South East up the hill, parking at 42.113809, -120.793403.
This last leg of the drive contained pretty deep ruts (presumably from people driving through the snow), a few mud puddles (even in October). Definitely need high-clearance and probably 4wd once you leave the gravel road and turn SE.
Dovre Peak, OR | April 2022
The Nestucca River Byway is a very secluded and off-the-beaten-path route through the North Coastal Range, between HW6 to the North and HW18/HW22 to the South. It's paved from Carlton at least as far West as the turnoff South to Willamina, but not maintained in the winter, so the sign says when approaching from the East from Carlton.
