We visited the Lower Shavano Campground in May and were met with cool temperatures overnight (20-30°f) and highs in the 70's. Them camp sites were large and well thought out with easy access to cut your own firewood and clean restrooms. Live water ran behind our campsite and was easily accessible to collect for filtering. There is a large trail head with access to summit Mt Shavano or stay in the lowlands. A relatively easy Jeep trail will get you up to the higher Shavano campground which was still closed in May due to snow.
