I hiked the trails at Lost Maples as a part of a hiking group.  We hiked the East and West Trails.  There are some fairly steep hills to climb, but they're not too long or difficult.  The views at the top are nice.

The signage in this park is very good.  Some areas are very scenic, but I was shocked by the lack of water in the creeks and rivers.  Many of them were bone dry.  Still, this is one of the nicer places to hike and would recommend it to others.  My understanding is that the leaves "turn" at the end of October/early November, so this would be an ideal time to go.  It should also be a lot cooler then.

We started out first thing in the morning 9am The weather was just right the trail was well marked except in certain areas in the river bed were we thought we were surely going the wrong way> Loved the several creek crossing don't recommend the norht loop it was a waste of time would of rather of took the east trail would recommend this hike to any one

Take note that when they say "steep" on the trail map, they really do mean it.  I could only do one of those steep sections (up and down the other side that is).  Another one would have had me not walking anywhere for a week.  At any rate, it's always odd standing in line at a state park (on a weekday at that) but if you go to Lost Maples around peak color time then I expect you probably know what you're in for.  Took the East Loop, with a spur of the West Loop to the spring area and back.  Great fun overall.

We started off the hike in search for isolation, and thats what we found. We started off initially towards site H, but stopped at C and G to check them out as well. Site H is definately the furthest out and the most Isolated. There is a steep incline right before you get to it that will definately make you appreciate arriving to the site. Although it is on top of a hill, there is not much of a view due to the dense foliage. We ended up setting up at site H because it was getting late. The next day we traveled up to the scenic overlooks which were great. The wind was probably 20-30mph and there was a light drizzle. It was fantastic weather in my opinion. We hiked along the creeks, off trail, which was one of the highlights of the trip. That along with the ridge over site C was the best part.

We hiked the Maple trail a while back and didn't see anyone else in the park. It was after work one evening and it was wonderful. We couldn't wait for the leaves to change to come back and hike the east trail. If you're going for a good work out, hike the entire East Trail. It's a great hike. If you're going to see the maples but don't want a strenuous hike, go about 1/2 mile up either side of the trail. The middle of the trail requires a great deal more effort and the views aren't nearly as pretty as the beginning and end. There are a few really nice views when you're up high, but they really aren't that great. We went on a Saturday when the leaves were beautiful, so there was a line 1 1/2 miles long to get into the park. It was pretty full, but everyone was really nice. I gave solitude a 3 to average out the absolute solitude of our first visit and the absolute lack of solitude from the second visit.

i must say i was a bit dissappointed.  when you look at the website it has loads and loads of pictures of glorious trees but when you're actually there...it's only a tree here and a tree there that are changing.  still very pretty - the drive was delightful. 

the hike was enjoyable enough but by the time i got down it was sooooo crowded i left.

My wife and I are new to hill country hiking. We made this video of our trip to Lost Pines. It's a bit silly (was meant for family) but gives some good shots of the scenery:

My wife and kids all hiked with me, we took our time and let the kids play and  still completed the hike in well under four hours, this area of the hill country may be the prettiest I have hiked. Clear streams, almost no one in park during the week, only a few swimmers in the creeks. We stayed in cabins just a couple of miles from park, but I can't remember their name, just look up vanderpool cabins and I am sure you can find the information.

Nice hike, was a little crowded but the park rangers told us in advance there was a boy scout troop there so we stayed back in west trail loop in camp site g.  it was really nice and only one other family was there.  Going to try to go back in the fall to see the maples.
