There's a super difficult scramble in the very beginning, but then it levels out and is not that hard, just a bunch of ups and downs. We had planned to take the blue trail there and then the violet trail back, but the violet trail turned out to be just a simple walk, so we quickly switched back to the blue. Very fun overall, and a nice challenge! It took us 3.5 hours round-trip, with about 30 min of lunch.
