Encountered a few snakes starting my hike, unfortunately I wasn't able to finish because of the baby rattlesnake that was in my path. 

This time of the year the trail is hefty with snakes. 

I completed the walk before during winter and encountered none around that time. 

It's a cool viewpoint forsure, just be safe out there folks.

Gorgeous day in eastern Washington to enjoy this small but serene hike overlooking Columbia River. Small parking lot houses about 4-5 cars and there were only two other cars when we arrived today at noon. Twin sister rocks are visible right in the parking lot.  Short ascent to the summit and wild balsamroot flowers are blooming everywhere along the trail. Basalt formations, blue skies, sunshine, that perfect cool breeze and views of Columbia River made this very enjoyable picturesque hike. Check it out if you are in the area!! 

A very nice drive and short trip from the Tri Cities.  Came across a few hikers including a family with small children.  Weather was nice and a breeze was coming into the gap.  Bring water, hat, and binos. Lots of fun. Take along a trash bag, some folks leave their trash behind and there is no trash can.

Trip Report for Twin Sister Rock and Wallula Gap 4/28/2023

First time to this part of the state and choose to combine two short-mileage hikes.

Started at Twin Sister Rocks arriving about 9:30am on a Saturday morning and only one other car in lot.  The lot is directly on Highway 12 with only space for about 8 or so vehicles.  The ascent is mostly straight-up with several spur-trails that we stayed away from, per the instructions on WTA page.  The trail is in good condition and winds its way up to the twin rocks for barely a half-mile.  There is a section of scree close to the top so be careful.  The views of the Wallula Gap behind you and Columbia River in front are beautiful!

However, be aware - this is rattlesnake country and on the return we crossed a section of rock that apparently startled the reptile who rattled and coiled then slipped across our path only a very few inches away from our feet.  We were safe but it got our adrenaline up to say the least.

Somehow I convinced hubs (despite his phobia of snakes) to drive about another mile up the road to then hike Wallula Gap.  (Not a lot but a few more spots to park here).  We choose the middle path that we think was the East Loop path.   (No signage at all). We went to the barbed wire fence and although no signage did not feel comfortable crawling under barbed wire, so we veered right and up to what may have been the South Loop.  It sort-off just ends at the peak overlooking the Columbia and even can see Twin Sister Rocks we had just finished.  We returned the same way and barely clocked 3 miles round-trip for the whole thing.  It’s a bit of elevation, but sweeping views with balsamroot in bloom right now and views of the windmill farms as well.

These are really nice hikes with lovely views of the basalt rocky cliffs and grassy fields, but rattlesnake territory put us on edge after the sighting. Also hardly any people hiking these. Only saw 2 others parties  

No restrooms at either location/parking lots - plan ahead.

This is an excellent leg stretcher on a road trip. My partner and our dog stopped here on our way to Walla Walla, after stopping in Kennewick for a round of disc golf. It's a very quick detour along 730 and is so worth it. The trail is short (but decently steep) and has incredible views over the river and into some excellent shrub steppe. There were even a few early season flowers blooming.

We visited on a sunny Saturday afternoon and there was only one other family out enjoying the trail. Just be prepared for some strong winds and ticks if you visit in the spring!
