This trail junction provides two options for exploration. The River Spur Trail contours along limestone ledges for a short distance before becoming a sandy path that ends at the Rio Grande. The river provides opportunities to view wildlife, especially birds, turtles, and fish. 
The Overlook Loop Trail climbs a limestone hill to a rocky outcrop that provides great views of the Rio Grande, the Sierra del Carmens, and the Mexican towns of Boquillas and Ojo Caliente. This hilltop is one of the best locations in the park from which to view both sunrise and sunset. As the name implies, the Loop Trail reconnects with the Nature Trail at a point previously passed on this trail.
