We went camping this last weekend (the first weekend in May) and had a blast at Beaver's Bend park.
Almost everything about the park was perfect... It was a gorgeous area, cheap to stay overnight in their (not so) primitive camping area, lots of wildlife and hiking trails. The only problem was that almost EVERY campsite was taken. We had to drive around several times to find one on a friday afternoon, and the attendant at the front desk had no idea how full the park was (?). My advice would be to get to the park early on a Friday if you're staying over the weekend, or else go on a weekday when it'll be empty.
Other than that it's a beautiful park for a weekend getaway. Also beware of the warning siren that goes off when the dam is opening - it's very loud and unpredictable, and sometimes goes off in the middle of the night. It's not so bad if you know to expect it. read more
