No showers in the bathhouse is a real gap at $145+ a night. Sites vary enough in size and shade that booking without checking individual photos first is a gamble, and mosquitoes can make summer and early fall genuinely unpleasant without serious repellent.

Visit in late fall, especially November, for the best combination of comfortable temperatures (mid-70s to low-80s by day, 60s at night), lower humidity, and excellent paddling along the Estero River. Fall brings fewer winter snowbird crowds than December through February but still offers pleasant days for hiking historic trails and kayaking. Expect moderate weekend crowds; weekdays are quieter. Summer trades comfort for afternoon thunderstorms, heat, and mosquitoes. Winter is peak season with fuller loops and more visitors from up north.
Peak season with warm weather, perfect for water activities. Book early.
