We went to the Bentson Rio Grande StatePark in Mission for an exploratory visit and were very impressed with the services offered. For $5 per Person …or FREE if you have the TEXAS STATEPARK PASS you have access to the park with a lot of hiking trails and bird watching blinds. You can also take a Tram to the trail heads so minimize excessive walking on the hot street OR you can rent bicycles for $5 and tricycles for $8.
We took a short walk in checked out the GreenJay Blind where we saw a few of them drinking and feeding. The next time we visit I would like to rent bikes, no need to bring ours and risk theft.
