The road to the trailhead is definitely crazy - our 4x4 Pathfinder took it like a champ! But, you definitely need a 4x4 vehicle to get through.
We pulled into the lot at 5am on Wednesday and there were only a few cars at the top parking lot.

This was my first 14er and it was the hardest hike I’ve ever done in my life! Definitely worth it! We had our 7 year old with us... and it was pretty difficult for him. We all summited Grays and enjoyed the breathtaking views. We didn’t summit Torrey’s. One was enough for us.
We took a lot of breaks with our son - it took us about 6/7 hours to reach the summit. We made it back down to the parking lot in about 2 hours.
