In Red Deer River Valley near Brooks, about 225km (140 miles) east of Calgary and 193km (120 miles) southeast of Drumheller, this park contains the world's greatest concentration of fossils from the late Cretaceous period. More than 300 complete dinosaur skeletons have been found in the area, which has been named a UNESCO World Heritage Site. Park excavations continue from early June to late August, based out of the Field Station of the Royal Tyrrell Museum. Much of the park is a natural preserve, with access restricted to guided interpretive bus tours and hikes. Space on these tours is limited, so be prepared to be flexible with your choices. Reservations are strongly encouraged in July and August. May through August, lab tours run so that you can view fossil preparation.
Five self-guiding trails and two outdoor fossil displays are also available. Facilities at the park include a campground, a picnic area, and a service center.
