Eagles Nest Lake State park campsites are pretty wide open like the valley it is in. There is a nice cement pad with an awning and fire pit. Not much else and I wouldn't recommend it for tent campers. There were a few people braving the cool nights and crisp mornings. Water available when you drive in and that is about it. So plan on boondocking. Our site was level and drive through. The drive through sites are not huge so if you have a big rig you might want one of the back in sites. The sky was beautiful at night with the milky way visable. If it wasn't so cold I would of been taking photos. Access to the lake is a relatively short walk and may change if the lake wasn't so low.
The lake is dismally low as the boat ramps are totally not usable. I don't know when they were last usable and it looks like it has been a while. The trail leading down to the Chama river isn't open, because the starting staircase is unsafe. There are other ways according to the rangers that stopped to chat. All sites are reservation only and that is important for those that just show up. You will have to go online and reserve your spot and cell service can be spotty. The campgrounds were patrolled by rangers and they were nice to talk to. Willow Creek loop was open and the other sites are closed during the winter. Nice abundance of trees and shade. I pretty place in Northern New Mexico. Many of the sites have water and electric. There are more primitive sites available too. Camping in the winter months was nice as there weren't that many people around. The toilets are closed during the winter months and the closest facility is the visitors center.
Fenton Lake is usually busy and reserving months ahead of time is a good idea. We like spots number 1 and 17 for tent camping. Rangers patrol the campgrounds and in general people are usually well behaved. Nice hikes along the creek. Getting a fishing spot may be hard to find sometimes as the small lake is usually circled with people fishing. Fishing is usually good though as it is well stocked. Temperatures at night can get down in the low forties after being in the eighties during the day.
