I live in Alberta, Canada and in 2020 I will be spending a couple of weeks in Oregon MTB and camping. I have reviewed a few sites. I am looking for a few recs of places to camp and ride. My thought is that I will camp in one location for a few days, ride a trail or two each day, go into town for a night, go out and make another camp for a few days and ride. You get the pattern. I read that Oakridge is a popular area. I will be by myself, with a truck and a bike.
North Umpqua Trail, great camping, multiple trail options so you can stay put for a day (or 3) and ride different sections at whatever pace suits you. Great trails, nearby hotsprings, the river. Hard to beat….buuutttt: +1 for Bend and Oakridge great riding in both places. Also look into Ashland and the McKenzie River areas. Ashland (Ashland Mountain Adventures), Bend (Cog Wild), and Oakridge (Oregon Adventures, Cog Wild) offer local shuttle services (and guiding, if you’re so inclined). Bring a growler for 180 Brewers Union in Oakridge (personally one of my favorite OR breweries), or Growler Guy fill ups in all the best mtb towns.
