THE EXPERIENCE OF BLOOD ROCK
EXPERIENCE THE FULL BREADTH OF ALABAMA’S LARGEST STATE PARK
• From ridge-top views to valley floors
• Enjoy gentle roadway sections, closed to cars
• Persevere through challenging climbs that are not on the map
• Explore backcountry sections of the park few people will ever see
• Run trails unknown to the public
• See secluded pools and waterfalls virtually unknown and unseen
THE CLIMB TO SUMMIT LAKE
This spring-fed quarry lake sits on the mountain crest, your reward for conquering the legendary Crack-in-the-Wall climb. The aid station here offers stunning lake views and the fuel you need to continue your journey.
THE JOURNEY THROUGH THE BELCHER TRACT - THE LAKES
Summit Lake is the highest lake in the tract. Next is Demopolis Lake, then Belcher Lake. Each offers its own unique beauty. These pristine mountain waters provide natural waypoints and unforgettable photo opportunities.
UNPARALLELED SUPPORT AND SOUTHERN HOSPITALITY AT IT BEST
• Aid stations every 5-7 miles with everything you need
• Hot soup, cold drinks (bring your own cup)
• Hot food all night
• Breakfast in the “wee hours”
• This is just part of what makes Blood Rock special
