Second Life has a number of parks with detailed scenery. But not many offer mountain trails. Fewer offer caverns to walk in. One offers both: Mount Campion Park. Standing over 300 meters tall, this is one of the tallest places on the Second Life mainland and offers a lot to see from winding caverns and tunnels to trails that go around and up and down the mountainside to detailed scenery. And if you want to stay a while, you can rent a cabin. Yours truly stopped by and had a look around.
