Legend9-14-26 Timberline East RV Campground, I do not think this is a KOA anymore. Tent site T1 & 2 was level and on grass with table and fire ring. checked in at 7pm, overcast, Molly was great at the check in, offered a 10% Veteran discount. $34 for the night. We only stayed one night. Showers and bathrooms were decent. T-Mobile was 5G 4 bars. Rained all night, you can hear the noise from the highway but you drown it out.
ScoutThis is a great location by the lake with some spots having great water views. You dont feel like sardines with all the space between sites. You can walk down to the beach as well in no time. We had a nice relaxing weekend. Will be back.
ScoutI love being close to the river and watching the birds.
GuideQuiet, clean, organized and friendly host! I ll be coming back!
TravelerThe campsite was great. There were campsites near the water and trees and then there were some on top of the hill.
TravelerPulled in looking for a good place to camp, but unfortunately had plans late at night and they shut the gate so they’re is no entering or leaving past 10:30pm - 6:00am which I think is a little stupid if I didn’t have late night plans though I totally would’ve stayed, sites looked great, and there was only one other camper when I pulled in.
TravelerHas a good view of lake on the tent side with no electric hookups, or water, although there is a small water spout that is like a hose we used to wash dishes and there’s also porta potty’s. There is about 11 sites on this side pretty cheap for what you get with them; they have a fire ring, picnic table Id give it a 10/10
ScoutIf you love being in nature this is the best place to be! It's almost completely all natural. And only $15 per night.
RangerGreat friendly hosts. Check in inside the gas station. Full hook ups and a fair price compared to most rv parks especially with good sam membership. No frills but adorably decorated. You got gas, snacks and great food and ice cream..what else could you ask for in a overnight stop. Laundry, shower house and bocce court. Bocce sets available to borrow from the gas station. Cute communal sitting areas one area with fire rings and wood available at the gas station. Yes its right off 80 and you will hear the traffic but with this incredible convenience we didn't mind. Felt safe and good vibes during our stay. Level and long gravel pull through sites and big rig friendly. Will definitely be added to our favorites list for I80 travels.
