One of the two days I spent at Eilat was hiking at Timna and I do not regret it one bit. We woke up at 4:30am (a must if you want to avoid summer heat) and took a bus to Timna. There is a 10-20 minute walk into the park (don't let others scare you about this walk. We had many people tell us we are crazy for doing this) and then the real hiking begins. You can walk down the main road, but it's boring, so we hiked all the way to the very top of Mount Timna. It was scary at parts, but the adrenaline kept us going. If you are not in good shape, this one's not for you. If you are, then the hike is amazingly rewarding.
